Hi, i have the same fault, the dealer has tried numerous times to fix itI had the MAP sensor changed the other day. Unfortunately that did not help. The check engine light came on after a short drive with the same error code, P2172. The light came on when I put the gear leaver in "P", which to me is a bit strange. That has been the case on the last two occassions when the check engine light has come on. How can that be?
I appreciate your response and consideration to me as a customer. I live in Sweden and I am in touch with a local Alfa Romeo workshop about this matter. They have been taking good care of me, although the case is not solved yet. There is also an ongoing case with FCA technical support. But thanks again for your concern.
My car has the same fault, my dealer has tried numerous times to fix it, but none has worked, last time they tried updates, did you get your car fixed & how was it resolved?
