My ECU part number in my E55 pulls up an SL55 ECU HELP!
So i am parting out my car. I bought it used and starting to find some interesting things. Like the ECU is from an SL55. Are they all backwards compatible? Will it fit an CLS55? I have no idea and can't seem to find any information on this. Part number is A1131530591. Please advise!
