PARDON THE AUDIO, LOWER VOLUME !!!! Took video with my cell phone when testing TCU. It’s either this video or nothing 🙂 Would not reopen TCU after sealing it.
The main power regulating chip number is 4267G. SOP package. This is very common problem with W220 S-class cars. Leaves block the drain by windshield and water enters into computer box and enters computers. Also, transmission fluid can also enter TCU damaging it. In my case car will not crank over. Main ME computer was also bad. Opened it and cleaned very well and it started to work, thank God. Very problematic to replace it as it’s married to the car. After ME-computer started to work Star Diagnostic showed that drive authorization is a go but car still would not crank over. There was no communication with TCU with Star Diagnostic, no indication of which gear the car in on instrument cluster. So ME computer would not know which gear transmission is in and position of starter lock out switch inside transmission conductor plate. I tried two other computers from ML430 and 2002 S500. Both showed on Star Diagnostic as “Unknown Unit”, car still would not crank but on cluster display came up showing which gear the car is in. So I attempted to repair original TCU, part number 0225455132. While checking voltages there was 5 volts on small power regulator on the right. But on main power regulator 4267G had pin1-12 volts in(correct), pin2-10.8 out(correct), pin3-0.8 out(should be 4.9 volts), pin4 ground(correct), pin5-0(should be around 3volts), pin6-ground(correct), pin7-0.8(should be 4.9volts). So no power would go to processor and other chips. Replaced power regulator with spare that came out of 97 Mercedes C280 TCU with damaged board. All readings came up correctly and voltages were detected on all chips. Plug it to the car, still no start before TCU had all codes erased with Star Diagnostic. Star had ALL codes possible stored into TCU, I had to scroll down the page. After all erased car started right up!
These TCUs are available from junk yards and not that expensive. I actually ordered one from junk yard but it didn’t come in yet and I already repaired mine in the mean time. That power regulator should not cost a lot and maybe this info helps someone. I could not find ANY info on repairing this TCU except for cleaning it with contact cleaner as either water or transmission fluid enters TCU and damages it.
I’m sure I can find and replace chips in these TCUs but probably cannot test them completely as they are different for different cars. If someone is interested you can mail me your bad unit and I can try to repair it. if it works we can work out the price for repair. Some TCUs are hard to find and Mercedes will charge small fortune for one brand new. Visit my site at www.RestoreYourMercedes.com and email me with inquiries. I do not check YouTube videos much.
