Hello dear forum! I have a specific problem and a general question about it. In short, in my XC70 II from 2008 with D5 engine according to current (admittedly vague) diagnosis, three ECUs were broken at once. Namely, the instrument cluster (DIM), the infotainment (ICM) and the central ECU (CEM). Can be even more but this can only be tested after these three have been exchanged. Computing should be seen with workshop costs of 3000-500€ symptoms as follows a us: During the ride the infotainment goes out and the instrument cluster reports errors like parking aid defective, brakes defective, airbags defective, ABS defective and more. Short time also total failures of the AI. Meanwhile everything works again completely normal and without messages. Reading the error codes results in 3 DinA4 pages with over 70 (mostly) communication errors. Guessless as I am, I would now like to exchange the ECUs for used ones and let them learn from Volvo n. Here are my questions: Is this possible and if so with which ECUs? and is there someone with similar history and a possible other diagnosis? Thank you for your help and opinions! If you need more infos just ask…
