Hello! Yesterday a took for test drive 164 Q4. Could you tell me whether is it normal when the car works on idle after stopping to hear a strange sound from the differential, something like "thump-thump" ? Sound is weak for a moment and the car is moving and working properly. Could this be some verification of differential?


P.S. I post this question and hire: Alfa Romeo 164 • View topic - Question about Alfa 164 Q4

P.P.S. Sorry about my terrible english! I hope you understand what I ask
Did you ask the owner? I would say it is not normal. May not be diff. Metal sounds are hard to find sometimes. Could be a ball joint or suspension issue.
