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.

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.

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.

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.

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).

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.

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.

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

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.

@@nickv4073 right, and if it doesn't work then the customer will expect that one hour of labor to go into the cost of the replacement unit. Plus, what if it works and fails again in 76 miles when the customer left for a family road trip. Bottom line, rarely worth the risk if a replacement module is available or unless it's your personal car and you factor in the risk of being stranded.

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

I believe the corrosion seen at 22:06 is perfectly normal and from the factory. It's the flux residue from a selective soldering process og the fibre optic component/connector. The flux residue is of a type that doesn't need cleaning (no clean flux) and is such left there. No harm in you cleaning it off though :)

I picked up a '08 335xi a few years back, one of the many small issues like your B7, was the radio wasn't working - I decided to dig into the amp as I read that water gets in. Yep, a bit more involved disassembling the Logic7 amp, but once I got in and found the green fuzz on a few IC's and components, I did pretty much the same drill, CRC and a brush - but I also got in with a jeweler's loupe and dental tools to scrape away corrosion (VERY Carefully) 3 years later it's going strong! I've also had a few where a solder joint wasn't great from new, or just cracked with heat cycles, and a quick touch with a soldering iron resolves the issue. great video!

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!

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.

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!

Enjoyed your video. I am in the electronic failure analysis business. Everything you did was mostly right. The yellow coating on the board in conformal coat and the light blue/white putty looking material is for heat transfer from a part on the printed wiring board to the case. This material gets squeezed during the original assembly process. Over time it will get hard and when you dis-assemble and then re-assemble, it will not have the same intimate contact for proper heat transfer. Using some new heat sink compound on top of the old compound is recommended or replace it all with new material. Never use a wire brush on any surface of the printed wiring board. If the soft bristle toothbrush is not aggressive enough, use one slightly stiffer. Best over all method I use is a mixture of DI water and IPA in an ultrasonic cleaner. Sometimes the area of ionic contamination is under a part and you will never reach it with any brushes.

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.
