Hi, I'm looking for some advice. I have a 2015 a3 1.4tfsi manual. I have started to have an issue with a clunking noise coming from the rear of the vehicle when changing up gears and putting the car in to reverse, the noise becomes more noticeable when the vehicle is up to temperature. Does anyone know what this could be ? Its driving me mad as I'm sure if it could be causing any damage.
