@daklakdigital3691 Год назад

IF ANYONE KNOWS HOW replacement part dealers screw the repair industry it is Louis as he has not only battled Apple and it's amoral business practices but he has spent time and money travelling the country publicising the cause. I am lucky, live next to China where it is possible to buy even copy bare PCBs from after market shops. But there again, I never buy anything Apple. Thank you Louis.

@somewhatofaprofessional7940 Год назад

BMW dealer tech here! Love you Louis and figured I'd comment that it pains me every single time I have to replace a control unit whenever something like water damage occurs. If it's customer pay and I don't have to turn it back in for warranty, I'll take everything apart just to look at the cause of failure. Unfortunately, with "warranty", all of these kinds of items (and every other item, for that matter) need to be turned back into the parts dept to potentially be sent back to the manufacturer for "inspection" so disassembly would void any of that and then result in my getting back flagged for my time or I'd do it with every one of the items. Unfortunately for me, I have to go through this on a daily basis. I genuinely feel terrible when I have to quote a replacement control unit + programming when I know that it MIGHT not be necessary. Those trunk lid control units have always been manufacturered like garbage with little to no protection built-in if something goes wrong. I've literally seen one fail and just catch fire. Literal flames coming from the center connector due to over current on a non-protected portion of the PCB. Absolute garbage.

@xpusostomos Год назад

Of course, the "maximum amount of money" they can get, isn't the retail price of replacing it all.. it's what a rational consumer will pay.

Of course they try to get as much money as they can. So do independent repair shops. That is business. They have a set cost for parts and labor... And they are in business for profit. If you can do the repair yourself, thats great. You will save a lot of money.

@gordonwelcher9598 Год назад

Sometimes the corrosion eats through the copper traces on the circuit board. A shop that repairs cell phones and motherboards by microsoldering can repair this. The NorthridgeFix channel has videos showing how this is done. They also repair keyfobs.

@admranger Год назад

My first job out of college in 1985 was at an electronics firm. I learned everything about soldering and cleaning/coating/assembling circuit boards. You did everything very well! BTW: the coating was called "conformal coating" where I worked. At a different company, we put the liquid coating material in a vacuum chamber to suck any entrapped gasses out for coated circuit boards going into space. Fun times.

@dylan-nguyen Год назад

Was about to make a comment about the conformal coating too Only thing is I would’ve used more solder to make a shiny joint and use some flux

@davidewhite69 Год назад

In the 80s I did the NASA 'high reliability soldering; course and the 'multi-layer printed circuit and flexible circuit board repair' course and yes it is definitely known as 'conformal coating'. we used to use a vacuum chamber as well, it worked better on acrylic coating than epoxy. we did that because the equipment I was working on were parts of the F/A-18 Hornet fighter

@villagelightsmith4375 Год назад

I recently talked with a marine electronics shop about their corrosion prevention for ordinary connections. (Saltwater is the worst.) I had dropped my cel phone in my sailboat's bilge ... They said their anti-corrosion potion is dielectric grease; for the rest of us; pure lanolin, straight off the sheep. Keep a meadow-maggot around the shop and you'll have a forever supply of the stuff. It's great to hear about the "conformal coating." Why didn't Chrysler use this stuff on their '76 Dodge POS's? for no money at all, they could have saved their marque from a bad rep that follows them to this day! Oh yes ... the cell phone in the saltwater? You should'a heard it screaming as it died! Sad. Run your car into the salty surf and AFAIK, it's DEAD! Burn or crush it quickly, so nobody gets stuck with any parts off the thing.

@bbb462cid Год назад

There's multiple types of conformal coat. They are not only not necessarily compatible (unless proven otherwise) but in some systems, the type of material is pohibited, Silicon for example. Even on Class 3 (mission critical/lifesaving equipment) PCB assemblies, brushed on conformal coats can be used, so long as the design supports it. Re-work and repair also may (or may not) support brushed on coating. Conformal coating for a PCB can be removed with your fingernail. Not so great for a car.

@murrys5444 Год назад

One addition I would add to your supplies are thermal pads. One of those modules had two pads on them. Those are to conduct heat from the chip into the case and dissipate it. It's a passive cooling system. Often they have a small amount of adhesive on them, and that electronic cleaner can remove it. You can buy sheets of thermal pad for not a lot (10-15 bucks), and then cut to size and replace. The main thing is to match the thickness of the existing pad. Too thin and it might not make good contact with the metal casing, too thick and it won't conduct as much heat (and could put stress on the chip and/or board).

@hunterpinnell6254 Год назад

Alex, an interesting side note on the fuel pump control module that you clean up and reinstalled. Those are known to suffer from heat cycle failure and become very intermittent in operation. I have a 2011 Alpina B7 just like the one you are working on and I chased this problem for the better part of a year. My car would be running 100% perfectly and out of the clear blue simply die. I replaced both high pressure fuel pumps, I replaced the fuel pump inside the tank under the back seat and the whole time it was this dang module in the back. When it would get hot (ambient temperature above 90 degrees) it would simply stop sending the correct pulses. Let it cool down and it would work again. My point is, even though you have cleaned it up and made it work again, I'd replace it with a brand new one and not have to worry about it again. I found a brand new one for 60 bucks and no longer have any issues. I am following this video series very closely given that I have the exact same car. Its 11 years old and running spectacularly. Keep up the great content.

@MrFlyNikolai Год назад

Do you remember what codes you were getting? I have a 2010 750Li & I'm having fuel system problems. First I use to get a lean code on Bank 2, then that stooped. Fuel trims still high in the low 20s Car idles rough & now it will randomly shut off. Codes I get when it shut offs...low pressure in the system & in the high pressure system, electric fuel pump speed too high And I'm guessing that causes the fuel injection to cut off. It's driving me nuts now, I ran a fuel pressure test in ISTA...and it checked out fine So idk if it's a vacuum leak that's causing all this, or some fuel component like that module

@straightsixracing Год назад

@alskooper3319 Год назад

I had a customer install his own battery. He connected the battery backwards. The battery post was completely melted off, metal spatter everywhere. I figured the car would need every single electronic module. Much to my surprise, the only module that fried was the fuel pump/srs module. I have seen those modules go bad on their own as well.

@svnbit8408 Год назад

@@MrFlyNikolai I didn't get codes when my hpfp failed. I've heard of particles contaminating the fuel system when this happens so just be vigilant about continuing to drive it, mine was intermittent at first it was only freaking out at startup where I assume it lost pressure in system but not enough to throw a code if it even would.

I've had great experience soaking the boards in a Tupperware filled with 90% rubbing alcohol. I put the container on my subwoofer at home and either play some music or watch a movie. The vibrations act as an ultrasonic cleaner and the alcohol dissolved the corrosion. I did this on a water damaged iPhone and MacBook and it worked both times. I soaked overnight and rinsed with some new rubbing alcohol. Brought back all my electronics. The issue with just spraying is, the corrosion can exist underneath the chips/capacitors that you can't get to with a brush. When it soaks and vibrates it gets everywhere.

I just used this technique to fix the remote radar receiver head of my 10+ year old Escort Passport 9500ci radar detector. After years of trouble free service it gave me a “check receiver” error. Since I mounted it behind my bumper when i installed it, I wasn’t looking forward to taking it back off. After seeing this video I decided to get after it. Removed the receiver head, saw the wiring was in perfect shape, so took the head apart. No apparent moisture got in, but there it was, corrosion between a couple of components on the board. Cleaned it off, put it back together, reinstalled everything and BOOM, it works perfect once again! Never thought it would be that easy, thanks for the great videos Alex!

Awesome job Alex! This should give a lot of us driveway mechanics some courage to face the daunting spectre of modern modules. Shared!

@MM_in_Havasu Год назад

Great video, Alex! Repaired our 2011 Ford Fiesta end of last summer after the ABS pump went bad and Ford service charged us $205 to tell us this, had previously replaced the master cylinder and bled the system to get all air out, including an ABS bleed cycle done with my Autel scanner. The resultant difference of opinion with the service writer and managers caused things to go downhill fast, at which point took the car home and fixed it myself. Bad ABS pump itself has the exact same symptoms as a bad master cylinder, made it difficult to diagnose the problem correctly. I bought a used ABS pump & module assembly off of ebay for $85.00 for the car(new cost over $800 from Ford, but had been discontinued), swapped my electronic module onto the new used unit and bled the system again with pressure bleeder and ABS pump cycling, works like a champ!

Yes!! Happy for this video. I am planning on purchasing a b7 and after two years of research and reading this video is the icing on the cake. Plus I love anything 7- Series related.

Amazing video, and well done, Alex. Learning so much from this channel, after your MB series... Thanks for the channel- from a guy in Army Medicine

@MrGattor33 Год назад

Great video Alex. Just want to say that you can a few extra dollars and use isopropyl alcohol for the chemical cleaner instead of the contact cleaner; does the exact same thing but costs just a couple dollars at your local dollar store 💁🏼‍♂️ Just some food for thought!

I pretty much started doing my own repairs on cars at age 15-16 buying used cars to get myself around to and from high school and jobs etc... Had a head gasket blow and got a quote from a shop my eyes fell out of my head. I took a look at a repair manual and said this is just a big 3D jigsaw puzzle, and went to work. Now I had to get a few things done by a shop like milling the head flat where it had warped a bit. I rebuilt my whole engine basically it was great.

@George-zq2sk Год назад

Alex truly impressive repairs on this! Love the content!

@mjra5121 Год назад

Great job. I'm always taking different electronics modules that don't work apart to see if they are repairable before replacing them. Contact cleaner is an awesome product to keep in the toolbox!

@richardthomas9263 Год назад

Super Impressed, I can work on classic cars blind folded but all the electronics in the new cars have caused me to quit doing most repairs besides regular maintenance. The tips you showed isn't just for automobiles, many things are so dependent on sensors and modules. Take a modern washing machine, very prone to problems with the circuits due to water damage and given some of your tips many could be saved instead of replaced. Keep doing what you do, your presentation was excellent.

@ENWILSON Год назад

I think this was my favorite video so far because repairing BMW’s is a pain but the electronics are often considered replacement items. Your wife is going to love having a B7 to cruise around in when she is not hustling people at the track in the Escalade.

you should def invest in an ultrasonic cleaner, would save u so much time with stuff like this

@M1LAD81 Год назад

I've been waiting for you to post another B7 video! The units that have that gel looking coating is actually called conformal coating. It's used to provide some liquid damage protection. You can buy that stuff as a luquid in a bottle similar to nail varnish or it comes as a spray. I've seen some people use actual nail varnish, but I would avoid that as nail varnish can sometimes have some harsh chemicals in it also, if you ever needed to remove the varnish, it would be way tougher than conformal coating which with a little isopropyl alcohol or just by rubbing it, comes off. Also, you can use an ultrasonic cleaner. Recently, I revived a water damaged DJI Osmo Pocket that showed nothing on the screen when turned on, but the gimbal would move about. First I tried isopropyl alcohol and cleaned the board with a toothbrush. I tested it and found that the camera gimbal did nothing at all! Then I tried cleaning the board in a bath of isopropyl alcohol in an ultrasonic cleaner for 10 minutes. Once I dried it up, I partially reassembled it. I was so excited when it came back to life and the screen was working. The only thing that wasn't working were the onboard microphones. I think the ultrasonic waves destroyed them. Still I'm happy the camera gimbal is working and 4k video capture is great! I can do a workaround with the microphones not working. Maybe in a future video you can try something similar. It would be interesting to see the results. Thanks Alex, for another great video. Looking forward to the next one.

Regarding the ABS unit, I suspect someone inserted a pry bar in that space (for unknown own reasons) and broke the case. That would account for the damaged circuit board, too.

I’ve done a lot of repairs on avionics in the 1980s, but this is the first I heard of using deionized water. Probably a lot safer to use than the mek and Trichloroethylene we used. Great video!

Hey Alex, thank you for your excellent videos, you make it look so easy, which enabled me to make the jump. I found a 2003 SL500 at a salvage yard, with a broken rear suspension/sub frame, from the previous owner playing chicken with a curb/pavement. After 5 months, and lots of evenings in the garage, i have managed to fix everything and bring her back to life. Its been an exciting and interesting journey, but with watching a lot of your videos, i was able to get it done!

@InNout8888 Год назад

Patiently waiting for the LegitStreetCars/M539 collab…….

@webmonkees Год назад

salvage yards are also a great way to upgrade the options. Car makers love saving so _usually_ the next tier of trim/switch/dash fits in. That's why they want to have everything serial number.. you know, for safety.

VW says we engineered an $800 failure prone computer to run the windshield wipers. BMW says "Amateurs. We built one just to run the fuel system." Great job on the repairs and the video! That was awesome getting an intro from Sreten aka RU-vidr M539. As far as the "dumb" modules are concerned, the real dummy is you if BMW can get you to pay big bucks to replace a module that didn't need replacement in the first place

@MindBlowerWTF Год назад

This is a PWM controller with current monitoring etc. This makes pump work less with less fuel demand etc. and is great for diagnostics. Just You know, don't dump it into water and it will work probably for the life of the vehicle.

Really surprised that so little of the control units have the conformal coating (the yellow protecting layer) on them. Do you think the infotainment system was supposed to be customized for Alpena? Instead of swapping that first module, you could desolder and swap the connector with the broken pin (or just swap that one pin perhaps) to revive the original.

JESUS CHRIST ALONE DIED FOR YOUR SINS & WAS RESURRECTED FROM THE GRAVE! HE IS ALIVE & COMING BACK VERY VERY SOON WITH JUDGEMENT (THESE ARE END TIMES)! PREPARE YOURSELVES, TURN FROM SIN & RUN TO JESUS! HE KNOWS YOUR PAIN & TROUBLES, HE WANTS TO HEAL & RESTORE YOU! TALK TO HIM LIKE A BEST FRIEND! ASK HIM TO REVEAL HIMSELF TO YOU & HELP YOU TO BELIEVE IF YOU DOUBT! DON'T WAIT TO CRY OUT! NO ONE IS PROMISED TOMORROW! HE LONGS FOR YOU TO INVITE HIM IN, HE LOVES YOU MORE THAN ANY PERSON EVER COULD, HE CREATED YOU! Jesus answered, “I am the way and the truth and the life.

That was a TCU and it would not impact the infotainment UI. It’s strictly for telephony related features.

@myxbigxfruitxstickx Год назад

Keep in mind with those fiber optic lines that you want to make sure the tips/connectors are extra extra clean and not scratched. You can have extensive signal loss if you even have a spec of dust on the tips. Also want to make sure the cable itself isn't damaged

@myxbigxfruitxstickx Год назад

@@cheeseburgerbeefcake I think they look more like FC or ST connectors
