Hello! As you can see, I am new to the forum and only a week ago proud owner of a TT-R , year 2003, 54 TKm, outside black, inside brown, with 110 kW :-)) I have a few questions here and hope for valuable tips: 1) Idle speed fluctuated, if you stand e.g. in front of the traffic lights – does someone know the problem? What could be the cause? Perhaps the idle stability valve? 2) I would like to install an Alpine radio. In the car is a BOSE system with Canbus – what do I need for it? To be honest, I’m a little disappointed with the original BOSE sound 🙁 3) Unfortunately I’m missing the Persenning – does one have too much? What does such a part cost? Thank you in advance!!! Greeting, Audi TTR fan!
