My A5 tdi is 4 weeks and 2k miles old. Thus far the rad' to engine pipe has fallen off, necessitating a flatbed recovery; then the particulate filter light came on - because the car isn't very good at commutes which don't get the engine up to operating temp. (I didn't see a note in the sales blurb about that..) Now the glow plug and ECU lights are on and I'm awaiting another flatbed. 'Not impressed' is the restrained sentiment. Anyone experienced similar?
