Hello municipality, I drive my dick since January this year, GP4, BJ 2015 and am so far more than satisfied. The following happened today: After a longer ride yesterday I parked the car, this morning at the start I immediately notice that the control panel of the climate does not glow and does not react, in addition, the volume of the radio can no longer be controlled by the buttons on the steering wheel, the Sign Assist is also failed…. the VAG World car warranty, but wanted to ask once in the round whether it could possibly be a little something that I could fix myself without a workshop stay. I need the car daily ….. Has anyone had this too and what was it? I am grateful for every tip.
