Who's going to pay for this? 

Dan you are awesome my friend. You make that shirt look good :)

It’s not just how good he is at finding faults, it’s also how good he is at explaining the journey and how things are supposed to work. I think the manufacturer should pay as they were the ones at fault, I wish you luck with that one!

In our family run automotive business in the UK, when we have come across this type of issue, we charge the supplier who in turn claim it back from the manufacturer. Great work showing the "behind the scenes" of vehicle repairs.

This guy is just amazing, the level of knowledge and the way he can express how things works etc... mind blowing

Your videos have incalculable value. Im not a mechanic but Im addicted to your videos

You didn't buy from the manufacturer, you got it from your supplier. The supplier, if any good, should pay, and he then should get the refund from whomever supplied him...

U know what dan! You should approach a production company and get your own tv show, your presentation and everything is just mind blowing, never underate yourself!

Used to repair computers 30 years ago and one of my favourite tricks was to spray components with freezer spray to cool individual components when dealing with flakey faults. Found so many dry joints and heat sensitive components. Those were the days!

Another amazing adventure.........no more Netflix for me! I will just binge all day with Dan. When I was a kid the best mechanic I knew used to taste the fluids that were leaking underneath the oilpan to make his diag. He would be turning in his grave if he could see this. Pure genius combined with dogged determination. And add to that, the skill and patience to communicate the whole thing to the great unwashed.......Well done Professor Dan. Thank you!

I’ve been in the trade for 30yrs Dan and I’ve seen lots of aftermarket electrical components that are simply sub standard,my thoughts when it comes to electrical parts is always where possible use genuine and in my opinion the after market part manufacturer should pay out for the loss of time spent on diagnosing this vehicle 👍🏻

Manufacturer should pay. Parts store should pay you and then get their money from parts manufacturer

The manufacture of the sensor, nice work Dan, Louis

Love your videos. I have been a mobile mechanic for 12 years and found that aftermarket parts can be a real problem like the one in this video. I believe that the supplier is responsible for selling parts that work and they should be held liable for selling "no good" parts. It is up to them if they want to solve the problem with the manufacturer. Too many times the blame game is played between the supplier and manufacturer, then they want to point at the mechanic to avoid accountability. Over time I have found that certain parts should always be replaced with O.E. from the dealer, no blame game and no problems down the road from the customer. Yes it costs more and can take time to get if not on the shelf but the car owner will not be back in two weeks because of a failed part. The customer does not care who is at fault, and the mechanic is the only one they are paying in the end. In the interest of the customer it is best to go with O.E. in many but not all cases. Keep up the great work.

Got me there.. 2 same brand sensors defect... Really thought someone put the bearing in backwards..

I love the little iron fillings card , it's cool how it shows the magnets on the bearing , a picture is worth a thousand words

Gosh! Sticky situation. Getting 2 bad products is going to leave a bad feeling. Again, your tenacity to not give up has me amazed. Wish I could find someone like you where I live.

Great video, Dan!!!! The MANUFACTURER should have to pay for your labor AND recall all of the bad sensors. Their bad parts are a waste of a lot of people’s time and money. Excellent work!!!!!!👍👍👍👍

Just be glad it was an easy accessible sensor and not a 2 or 3 hour starter or other buried device.

I’ve been lead up the garden path by faulty new parts before and it’s a proper wind up. Watching your videos I’ve noticed that you have access to such good diag and the wiring diagrams are brilliant! This is one of the things we struggle with on electrical faults, taking readings with no information on what the readings should actually be.

I have learned lots from you posting. Thanks for sharing and teaching others. I have a 2004 GMC Canyon, automatic transmission, 3.5 litre 5 cyl.The LTFT is +12 to 13 %. I decided to use my new scanner tool to show me live data while I was driving my truck, to see if I could spot any strange or concerning anomalies. Nothing showed up if I was just idling in the truck. I did find something strange while I was out driving on the road test. I set the scan tool to show me only 4 statistics: STFT, LTFT, O2 sensor #1, and O2 sensor #2. So on the drive, the readings of the 4 statistics would fluctuate up and down as a person would expect. Then suddenly while driving at about 90 km/hr, and 1750 RPM according to my dashboard readings, the scan tool all of a sudden showed that the engine was locked at readings of STFT 0.0%, LTFT 1.6%, Sensor #1 at 0.005 Volts, and Sensor #2 at 0.40 Volts. It was my understanding that the O2 sensor # 1 would always fluctuate up and down from zero to 1 volt while driving, if working properly?The scan tool showed these frozen/stuck engine readings at 90 km/hr, and did the same thing at 110km/hr. The fuel trims and the O2 sensors were frozen in the readings, for about 5 seconds to 10 seconds, without changing. Sometimes the voltage of the O2 sensor #1 would very minimally change to 0.015 v, and O2 sensor #2 to 0.050 Volt. I have been experiencing a lack of power and hesitation, at these exact speeds, in the weeks prior, so the scanner findings make sense, I guess. What do you think about this? Any of your experience and knowledge would be appreciated for sure! I’m guessing if it is possible that the lock up mode of the automatic transmission has something to do with it? To me it does not seem logical that while driving and the transmission enters into lock up, that it would ever cause an O2 sensor reading to freeze and the Short Term Fuel Trim to freeze accordingly? When I am at idle, the O2 sensor #1 seems to work properly…it fluctuates from say .850 and all the way down to .015 as a rough explanation. Is there anything that would cause both O2 sensors to die at same time? Oh, I forgot to mention the odometer is at 418, 500 Kms. Well, I want to thank you for all of your intelligent videos and your clear concise way of speaking. Gotto love your personality as well! Blair.

Changed hundreds of sensors over the years and I came up with a good few manufacturers that I always stuck to, plus they supply to genuine parts also. They are blue print, denso, Bosch, NGK/NTK/ apec for abs sensors never had a single failure from these manufacturers. Brilliant teaching Dan, just what we need, I've been in trade 6 years, haven't failed to fix something aslong as the tools were present. Makes a massive difference. I'm also self taught and use the training platform electude years ago, really good. Keep up the good work.👍

everyday i learn from diadnosdan even who will pay for this and that ... thanks alot wish you the best

I've been in the business 30 years. I'm having this happening more and more often. I fight with my supplier, even switched suppliers but all they will do is give me another sensor or credit for the bad one. As for recouping my lost time both my supplier and the manufacturer say too bad. Even when I buy an OEM part, and have a problem its the same answer. You're 100% right. The customer shouldn't have to pay for that but also the repair shop should not have to pay for that either. I don't know what the solution is. Worst part of it now is I start loosing confidence in the new parts and second guessing myself when diagnosing a problem.

top quality diagnosing .. the supplier is probably only responsible to exchange the faulty sensor . What a bummer .. you explained the / your faulting methods so well even 76 year old dummy like me got it .. Thanks again for fixing it again .

I too have been burned by “aftermarket” parts. At times they just are not worth the effort and time. As always good job diagnosing and presenting your material to your viewers.

Great Video Dan, funny how we brought out a video on ABS/WSS the same day :) Similar thing happened to me a good while a go with a LHF WSS on an Toyota Auris. New faulty wheel speed sensor lost me a lot of time and a bit of head scratching before rectifying the fault, I tend to check for good sensors then interchange them if possible with the faulty one on the vehicle, even if the wiring is longer on one to another it can be routed direct for a fast test. If quick and easy to remove I always go there first after that experience. Good info and I enjoyed watching it, keep up the good work.

I wish we had mechanics like you in workshops in Germany. Your are really good!

Love your videos, you are the type of guru that every shop needs, but no one have, with todays advanced cars, diagnosing and changing parts dosent do it, a deeper understanding of how sensors and electronic works and how cars comunicate is priceless

Eat the additional hours, it's part of the game. Great video Dan

Where were you my European friend when I was learning this stuff Wayback when? !! I absolutely love your videos and tutorials!

Wow Dan, that was a fantastic animation, explanation and editing of the video so that I could understand the sensor and the fix. I'm not in the business of auto repair but in all fairness the manufacture should pay for the lost hours. However, I know that could be hard, and how much more time are you willing to spend trying to get recovered hours? At the very least the manufacture needs to know they are producing faulty parts so (hopefully) they will correct the situation. Great video!

hi from ireland,the factory that made it should pay for your time,and keep up the good work

I did come across incorrectly fitted bearings, but never two new - good/bad parts for the same vehicle. As to your question, I believe that the best way would to charge the supplier, than the supplier recovers the funds from the manufacturer and everyone is happy. But in the real live we need to be flexible and in case you can't charge the supplier, than the supplier should make it up to you at the next parts purchase. Excellent video Dan, not only you are showing how to diagnose vehicles, you are also giving great tips how to retain the customers. You got yourself a new subscriber

It s awesome Dan, happy that you are compensated for faulty part. You have unleashed the real scenarios often encounter in the Automotive repair services. Even though I am not a professional I am somehow educated by your awesome video.

before ordering ,sometimes I would swap the good one (left) to the bad (right).

Now this is what I call a mechanic. Good Job man!!!

My experience is that you will get your money back and possibly a little good will. Trouble is suppliers, trust their's more than they trust their customers. Take it on the chin and always check sensor output after changing. Dan, you are such a great teacher, the very best.

Yourchannel was referred to by Eric O at South Main Auto in New York, USA. Great diagnosis job. To answer your question, the mfg. should pay for the wasted time, but in reality I doubt you will ever see a penny out of them, based in my experiences in the electronics industry. I ran into the same problems with bad electronics parts. It got so bad at one point, I had to check every part right out of the package, and refused parts made by several "name brand" mfgr's., as they had a record of selling defective/ DOA/ out of spec. parts.

Fantastic video, as always Dan. As a shop owner and tech for 30+ years, I am SO SICK of faulty parts. It seems all parts manufacturers are going to China to save a few pennies and pocket the profits. We, the shops and, ultimately, the consumers pay. The labor lost is almost never reclaimed in my experience. I try to keep track of which brands work, and don't. I note on the invoice my supplier and brand, as well as country of origin. The parts don't always come out of the box bad, usually it's a failure shortly after install. I check with my supplier on returns. If an aftermarket part has a well under 5% return rate, it seems a safe bet. Anything over 10% return rate is a red flag. Keep up the top notch videos DD!

Great Video Dan and definitely the Manufacturer should pay for your diagnostic.

Hi Dan, replaced 6 glow plugs on my Jeep Grand Cherokee 3.0 CRD, original parts from the dealer. Two failed within one month! Replaced the CR2032 battery in the remote after 10 years of use. Within 2 months the SKIM module started to act up. Car would start but the engine would cut out after 5 seconds. Went through the entire diagnostics, turned out to be a crap battery in the remote. Funny enough it had enough power left to unlock the doors but not enough to send a proper key ID. Boeing found out a couple of years ago that there was a huge counterfeit spare part scam going on that had even reached the Airforce one. I let you guess what country these parts came from... Great show Dan, I have learned a lot. Cheers!

Damn I did not see that coming. I think OZ should pay for it its the curse of his shirt. Keep'em coming Dan you are AMAZING.

Great Video as always, I've had this problem several times, What I do before ordering a second sensor or even the first replacement sometimes is to make up a left to right bridge cable (as we know you cant get an old sensor out in one piece to swap sides with and some are shaped for its side) and check if the fault code changes sides.

Good job fix Dan , hard decision who's going to pay , but my respect for you good mechanic👍👍👍👍👍

Should be the supplier if there any good. Most of the time they will cover all or half of the cost. That's only when the parts/sensor is DOA. Great work! It's nice to see someone who cares about getting the job done right the first time without over charging for parts or labor.

cheap people pay twice as my grandma said... sometimes it is better to stick with OE parts or the verified premium brands that produce parts for the car manufacturers. Today, we have a lot of junk/counterfeited parts around from asia... you know. Btw, great job and very educative video.

For those kind of things, I need at least one beer to clear my mind.😉 Dan you really have things sorted in your head. 👍 You fixed it again and I learn something from you again.😎

You’re just amazing. You are so talented and methodical in your work. You should be teaching ( I mean you are teaching us, which is greatly appreciated).

Wow !!! You are a very genius guy... you always follow the specific way whenever you provide every single trouble shooting on cars. Sometime I do refer your you tube video in my own workshop internal training class for my staff, thanks for your well prepared video and for your systematic practices. I really love it.

Wow, who would think new parts/bad? How many other shops got stuck with these sensors? Liked!

Another scenario where "new does not mean good." Also, I would consider any effort to seek restitution from manufacturer to be not just costly but, ultimately, futile. Move on to the next battle knowing your intellect and skill prevailed once again. Excellent presentation.

The supplier should definitely pay Dan ! Well done 😀

My name is Alf from Australia. I guarantee my work. I’m a self taught (bush mechanic, self taught I started at 19 yrs and am 72 years now ). When I saw your video on wheel sensor after market unit, and you asked for other people’s opinion on who should pay for the extra time . You guarantee your work , parts’s people (if proven faulty should guarantee there product ) but as usual they will give you another one and replace it, but you will have to carry the burden of lost time.

I'm a DIY mechanic, the way I would have done this is simply move and install the wheel speed sensor from the left to the right (if it's possible). and then measure the voltage with a multi-meter when spinning the wheel. but great video though...yeah alot of aftermarket parts are crap.

Great video Dan. Reminds me of a GM car I repaired several years ago. It was an issue with a thermostatic cooling fan switch. I diagnosed the sensor as being bad, replaced it with an aftermarket sensor and still had a problem. After rechecking all the circuits (I spent hours) I decided to try another sensor. The parts house sent out the same aftermarket brand and I installed it but still no fix! My last hope was to order an OEM GM part and that fixed the problem. So I received two bad aftermarket sensors, which reminded me of what you presented in your video. As to who paid for it? Well our shop wound up "eating" the labor. I couldn't charge the customer and the parts supplier was no help. Lesson learned that sometimes using aftermarket electronic parts is not always the best option!

Had the exact same fault with a BMW. Some aftermarket electronics are shocking nowdays. I got my parts refunded and put a labour claim in to the supplier. They did pay me but not at my hourly rate. Keep up the good work Dan.

Super smart and ethical technician/mechanic!! The supplier should come good for it and the manufacturer should compensate him. Great work!!

It looks like Europe has its own brands of Doornail,Broke When Delivered and AcDead. Professor Dan fixed it again! 💪💪💪

Great video Dan, it just goes to show the pitfalls when using aftermarket sensors & parts. Personally for me, two invoices would go to out. One to the customer that sent you the car, for diagnosis and fitting of sensor and one to the part supplier for time difference fitting another sensor (wasted time). Imagine if you had a lift tied up because the part was faulty or if you had to refit the wheels and drive out to clear the ramp so you could do something else whilst waiting for the 3rd sensor, or worse, you were mobile like me and had to wait at your customers or drive out to collect the new part. Both a loss of time and money. It would be then up to your customer to claim your invoice back from their parts supplier. Nice shirt btw, although it looks a little tight lol

Hi Dan had this in the past. It should be the manufacturer that pays gor the labour. Love your channel.

You’re awesome at teaching and diagnosis!👏🏼

Lesson learned! Test the new part prior to installing, as you did when you plugged it into the left side. You have, in a matter of minutes confirmed the new part is good, (or bad) prior to installation!

My first bet was that the bearing was changed and the sensor is either always on or always off. I would not even think that it is bad out from the box. Great work mr. Dan. I really enjoy your content. Thank you for it.

Wonderful advice from a wonderful person, i always learn something new from you, god bless you

What does Keith say....NEW = Never Ever Works? He's freaking right! In this case I think that showing on video the manufacturer of the defective aftermarket sensors is payback enough so other people don't buy their junk haha

One reason to only use OE parts. I have seen too many "aftermarket" parts fail right out of the box. So If you don't want to pay dealership prices, find who the OE maker is and buy that one.

The manufacturer should have to pay for all that time. Love the channel I think what you do is great and it's great how you explain it

The supplier who can then claim from the manufacturer ,you dealt with the supplier who acts as an agent for the manufacturer great video thanks 👍👨🏻‍🏭🇬🇧

Dan love the intro it's great. I hate crappy aftermarket parts. The manufacturer should pay but that is never as easy as it should be. Eric O Had a similiar issue with starters last year.

Always a great inspiration. Thank you.

Excellent video. These ABS sensors are Hall Effect devices that give a 2 to 20mA square wave output. The ECU detects the current changes by measuring the voltage drop across a shunt resistor. If the impedance of a replacement sensor doesn't match the specification of the ECU, it won't work. In this case it was mis-matched by taking too much current. All interesting stuff. Well done.

Like how you go through each step, you should have million subscribers, my opinion. My car been in the shop for a week before they made a guess and might be fixed.

You’re a great 👍. Tech/engineer your an amazing Teacher The Supplier should pay 💰 for it ,,,, they should stand behind the product they sell I all ways try to buy oem electrical Parts Depending on price it’s happened to me before with a coil pack everything else after market is usually good enough brakes shocks etc here in North America there’s a lot of after market shit on the market 👎

2nd...😁😁 I would say if they supplied a faulty part the cost should be paid for by the supplier...it will however be pushed towards the manufacturer who will never admit fault. I had the same fault with a supplier giving me two incorrect starter motors for a mondeo stating this was the only starter listed. From the main dealer i got the correct one first time. The supplier would not pay towards my lost time haveing to fit the starter 3 times...

Excellent videos. I've had this happen. It sucks but have never been able to get the lost labour covered

Dan you’re the Sherlock Holmes if Auto Diagnostics and take the time to spell it out to you viewers. For that I’m very grateful and wish you worked close by as I’d pay for your time in a heart beat. 👍🏻👍🏻👍🏻🏴󠁧󠁢󠁳󠁣󠁴󠁿👍🏻

Great channel. Glad I found it

Wow Dan I didn't realize you were a fashion model nevermind a talented tech! haha

The Manufacturer , They boxed , Shipped and Smiled when you bought it !

You would like to think the manufacturer would pay for it, but don’t hold your breath. Nice to see a professional with skills at work.

Who ever took the decision to go with an aftermarket chinesium part has to eat it, any non OEM part comes with risks, i am not saying OEM is flawless but its DOA probability is close to zero due to factory's strict quality control that's why I always advise my customers to go with OEM, it's good in the long run and will save them and me the headache

Well I would Love the challenge of the diagnosis victory and realize what a valuable lesson it was so with that said I would writeoff that brand and it's entire product line realizing their production line is manufactured with very low-quality control thus saving them millions but passing their products off as quality. Now I would appreciate my "supplier" offering retribution for falling prey to their purchasing sub-par products wasting everyone's time in the process. My supplier could have caught this if they received a substantial discount to purchase this line, otherwise, they also fell prey to their supplier's sales tactics.

excellent video Dan ! love your dedication & knowledge ! in answer to your question, i believe the manufacturer should pay, after all they are the ones who should test and quality control the product to make sure it works before it leaves the factory. the supplier simply stocks the part !

You're great. Full of knowledge hands on no how to. Thank you.

The manufacturer should be paying for it but it’s always the shop that loses out

I think these are losses we just have to take. I dont think the manufacturer will offer you any other restitution than a new part that you dont want or need. Only thing you can do is to let other people know so that they stop stocking the bad parts. I usually try to buy bosch sensors if they are available if they are not I'll try to find other OEM brands they might at least be more likely to compensate and also they are not that much more expensive these days. But also depends on what the customer is prepared to pay for.

Nice work here Dan. Ive been there before, and the supplier never pays, they just supply the new part and call an end to the issue - we always loose out on the labour. We end up charging for our diagnosing time.

I practice my English with your videos. I from Venezuela and You are amazing

I know little about auto electronics but I like the logical way you work. So I’m trying to work out what happens if the MRE shorts (which seems a very odd thing for a resistor to do, but MRE’s are completely new to me - in my experience resistors mostly go open or more commonly high value and usually from over heating or too much current) So you got a reading of 2.4V with the faulty units so the internal resistance is somewhere between 5 Ohms and say 50 Ohms assuming it draws a minimum of 50mA. So the unit must jump to that internal resistance when it reads a dead short across the MRE to give that 2.4V reading and the CAN error code. Correct? Just trying to learn. You fooled me - I thought for sure you were going to say the wheel bearing was on the wrong way around and I’m not even sure if thats possible - LOL

This happens far too often and is so frustrating! I always charge the supplier

Regarding who pays. The Customer, Any goods supplied are warrantied under replacement only, Engineers do their best, manufacturers do their best, but batch test only, Customer buys at risk. Its why we change vehicle when makers warranty ends!!!. Dan, you are brilliant and entertaining

Tricky issue! I wonder what happened with all the other wheel speed sensors of that brand, which ended up being installed in cars? Anyway, the explanation is excellent, and the logical framework of the process is genuinely instructive.

Quick addition when looking for a pulse ring on your new wheel bearing..grab some brake lathe shavings and sprinkle it on the bearing. The shavings will stick in a pattern of that of the pulse ring

Diagnose Dan can he fix it? Yes he can!

Hello,I follow you every day almost.I have just discovered your channel3 weeks ago.Please keep making these videos.I am an automotive enginner but I work at a corporation.My dream would be to be able to have a diagnose shop.I love doing the things you do.

Classy and accurate presentation. Well done.!

I give cutomers a choice OEM or aftermarket I explain the risk is on them as aftermarket won't cover my time that way they choose and are charged accordingly(either for the part or the extra time(if part NFG))

Usually in US when this thing happened the part supplier pays you back and they get the money back from the manufacturer it's that simple

Dan you and Eric O could open your own diagnostic shop. Great job Dan.

As always awesome diagnostic work. It turns out that the sensor you replaced and the one the other shop replaced were deffective. You both dianosed the problem correctly but a deffective part gave you both a head ache. At some point I thought it was the bearing that was broken. Then I thought you should have swaped the sensors, which you kind of did at the end. Congratulations on your great videos.
