Did the Dealership diagnose this car right? 

I’m definitely not a professional auto mechanic (I’m a retired aircraft mechanic/flight engineer) but I sure can tell when a knowledge person is methodically troubleshooting.

Your Great Dan,.. awesome I also fixed by doing option 3 as its more economical solution.

Great repair. I'd have gone with the customers choice

For those like me interested in the magnetic wire holder, google for "Lisle 55000 Wire Holder"

Nice scan tool 😉 as always awesome work well done. I also would go with third option due to vehicle age.

Ha ha I'm happy and customer is happy!

Dan ur diagnosis skills are amazing I would never make repairs to any module even if it was a cold solder joint because of liability ur repair to the signal ground was correct intermittent problems are difficult

@@Diagnosedan Happy until selling the car, and someone sees that patch. Then wondering how many other undocumented patches that exists. A rebuilt replacement unit is always the best. If one solder joint on the ABS PCB has come loose, how long until another one comes loose. This is a typical problem when manufacturers went from lead based solder to non-lead solder. Re-built is always the best option.

I would take option 3 and offer to pay EU100 because people like Dan should be encouraged to exist and prosper

@@catalinnicolae4443 I would take 3 but so many people believe that unless it comes from a manufacturer the job isn't done properly or has enough quality control measures.

Your welcome Steve!

😂😂😜

You'd think they would want to spend diagnostics money more than the expensive part changing wack-a-mole many places like to do.

Good job love you Dan

Maybe you diagnosed it😜

DiagnoseDan ahah no sadly not, I’m far far away in Canada 🇨🇦 lol

Makes sense!

Now that I'm going through the comments I feel like I copied yours lol

option 3 doesn't cause anything and is not irreversible. option 2 makes sense when ABS module starts acting up again. till then option 3 it is.

It may or might not, 10 years ago a friends civic just wouldnt start, he took it to diferent shops, Relays, wires, connectors, pump, filters, inyectors were replaced and notheing worked, i happened to be visiting him and he was planning on just scraping the car, i tested it a bit, some wiring diagrams from the internet and found no signal from the ecu to the pump relay, we opened the ecu and with a magnifying glass i found some sketchy solder mixed with flux, looks like an error on the factory or some refurbishing stuff (he bought it used so no idea and its a no sealed ecu, no signs of a repair), just got there with new solder and it worked, the damn car still runs perfectly

I think 99% of the workshop in world will simply change ABS UNIT alll cables and sensors. RESPECT for your patience to discover real problem and avoid overcharge customers.. By the way how you have this wiring diagrams animation with all info.,parameters,voltage values. Is a special software? A name will be useful.

Thank you very much

And Australia!

Check out Scanner Danner’s channel in the US. These two guys have the same passion.

South main auto n pine hollow diagnostics are good US channels

Dan sure knows his stuff and his diagnostic procedure is up there with the best, but you should take a look at LM auto repairs this guy really knows his stuff too...

Great! We can do that in another video!

This was my thought , as well. On someone else's car, however, it's risky unless you've done it before.

why it has inside ground?

@@johnaclark1 Yes, this it is not a job for everyone

Some people learn from the video. So, i believe it will help to diagnose and do some minor repair or modification.

damn right , have audi with faulty injection pump high pressure fuel pump that cost €9000 and the car cost €4000

Mark Phillips That the Ivan option.

We can do that in another video!

Not always an option. Some of these units have aluminium joints which won’t take solder. Had a similar issue on an e38 a while ago, the abs unit looked very much like this one so probably manufactured in the same way. I cut the top off it thinking it would be a nice easy job to solder up, it didn’t go as planned.

Dan, that would be Cool. Dry joints are a real problem in modern automotive electronics. A few cars I've owned had electronic problems of one type or another due to poor solder joints. Luckily I know how to repair them. I tend to buy big cars with lots of electronics in them, so I get to see these issues. My current Lexus had a bad reversing camera. Luckily with that a cheap Chinese camera fitted in the housing and made a good replacement with slight modification.

As my brother used to say :everyone can change new parts, but he is a mechanic how can play with old cars and parts.

Thank you very much Paul

Fair comment!!👍👍

"As it was built" with a fault!

@@peterr1342 yes VAG life for me when the engine light goes off i start to worry

Yes and after that straight to museum

I noticed the Audi had over 270 thousand kilometers on it. Factor that in with the age of the vehicle and it is very apparent that this vehicle is nearing the end of its practical service life which makes option 3 a more logical choice in this specific case. As stated this fix will function every bit as well as repairing or replacing the control unit. It always seemed stupid to me to task the control unit to perform the duty of supplying a ground to the sensor when a piece of wire can do the same job.

Thank you very much

Some dealerships are really good!

@@Diagnosedan that's good as in any trade theres always a few bad Apples that ruin the rest

Thanks for the fantastic comment!😊👍

Ha ha ha 😂😂😜

Thanks for leaving a comment it's appreciated!

Thanks!

Same exact problem on older BMW. It was so common that we used the heat gun if the abs light came back on.the module was faulty

True! We can do that in another video!

But if there were more then other faults will appear, but there has only been one fault.

Would keep it at 3 and if more codes appear, then option 2, or frankly just trade the car.

Vielen Dank!

Then you know where the fault is and you can go for op 2. If not, you have saved a lot!

Not necessarily. 1990's gasoline Mercedes had faulty fuel pump relays manufactured by Bosch. I took them apart and resoldered them. If you bought a new Bosch fuel pump relay it would have the original built-in Bosch fault which was a badly flow-soldered relay socket.

Opción #2

3

I agree , pull an Ivan and do the reflow repair!

+1 i wouldn’t trust on this ABS unit. When you need it, it must be 100%.

@@roybm3124 The owner has been relying on it since it was new. It was soldered to begin with. Done properly, the re-flow will be better than the original, as the original has failed to begin with.

It might be difficult to remove the circuit board from the unit. The damage in the circuit may not be at a solder point. Re-flow is the most elegant repair but has its limitations and risks too.

I've experienced some ABS modules that light up the ABS bulb on the dash yet they still function normally ! Likely a cracked solder joint or something else not needing much current to set the bulb on.

Ha ha 😂 Bedankt!

I didn't' know what you said at first as my second language isn't Dutch but is Spanish. After Google translating your post I agree completely, any uncertain intermittent issues I'd gladly have Dan do the work even if it cost me some extra money for his actual labor time as I'd want to reward him for his meticulous manner of performing the job to get it done correctly😊👍 rather than spend that money using a "parts cannon"!😜

I would have chosen option 2 also.

Well maintained car!

Ha ha LoL😜

Most shops would have traded out parts till they got a hit then bill you for all of it.

😂😂👍

And (for a change) also in England !

also known as occy (octopus) strap in Australia.

Thanks i didn't know that!👍

Hi Dan, I love your channel, very good info always given. The first bad thing I heard you say was those bungee cords. They are dangerous ! One shop I worked at, Guy lost his eye to one. Just Google the stats and you'll see. Keep up the awesome videos !

@@rooster3285 Operator error, never over tension them, use the right length and make sure they are secure. I have been using them for over 30 years and never had an issue.

Yes that's true!

Was looking for this comment

We can do that in another video 😊👍

Don't screw it up than😂😂

The wires in the b6 abs controllers that require soldering are smaller gauge than human hair, so that would probably be accurate. Additionally, there is a gel substrate that is there to protect it that can only be removed using acid.

Scoobs McGee me too

I fixed 5 ATE modules by resoldering through the silicone seal, cutting open the unit is worst bit.

😂😂😜👍

no u

And that's why nobody likes you. Lols.

Got my grounds checked, and they work fine. Sub-ohm results :D Karma will strike those who dislike me eventually.

Whaaaaaaaa LMAO.... That's hilarious! I personally use Chrome but mostly just out of habit! Internet explorer use to give me constant issues and always just seemed slower then chrome to me personally, but hilarious ass comment nevertheless lol

Thanks for taking the time to leave a comment

Definitely, parallel paths are not always good. Ground loops can cause other failure. In thinking about it now, I might actually cut the wire from the abs control unit and cap it until the unit is fixed.

😂😂👍

Thanks Jim!

😜👍👍

Why exactly would you fix something not broken ?

@@iamasmurf1122 I love when people don't get jokes...

Thanks for the comment!

Its not a very expensive car at this point...

😂😂I wasn't there and don't know how they came to that conclusion but they were right!👍

@@Diagnosedan they were right from probably guessing it was faulty.

@@AndrewSparkfish Because they already had seen it many times before.

They can make the most profit with the least intellectual effort by replacing the whole unit... If the cost is prohibited then they go to standard service /marketing operating procedure and their preferred option... Trade in value applied towards a new Audi.
