Hello together. I have the following problem with my V50, Bj 2005, 1.8. At Volvo, they found that the control unit is probably broken, which is located in the steering wheel.This is responsible for all functions that are on the steering wheel. My question is whether I could also install a used control unit? If so, does it still have to be coded? Are there professionals here who can answer this question?Or sufferers who already had the same problem. At Volvo, they want to have the 600 Euro for it. The exchange is no problem for me. Please let me know who can say something about it.
