Hello, I bought a used 2000 v70 a year ago, and four days ago I began to have acceleration problems. The dealer at first told me it was the knock sensor and replaced it, but now they claim the entire ECM needs to be replaced. I asked them if they could find me a used ECM, as hey have found other used parts in the past, and at first they agreed, but just called me back to say that a used ECM would not work because each ECM is linked to the vehicle's VIN number, and if it doesn't match the actual VIN number of the car, it will simply not function. This sounds a little suspicious to me, though not impossible. Do any of you know if I'm being fed a line?
Thanks a lot!
