I think it always helps. Reason being: the car is compltely visible inside and out. Sometimes videos helps in explaining better about the car rather than just pictures.
I have always heard that transmission problem is a common issue in Audi S5. Is it really true? I have driven my friend’s audi S5 and I kinda feel the same issue. The transmission jerks badly.
Dude its kinda serious. May be the brake pads are spoiled. If that is the case, it’s really dangerous to drive. Please go back to the service center and get the job done.
