2 weeks ago I bought a GP3 EZ 2011 with approx. 150k running performance. During the Dekra test it was found that the front tyres outside, and rear tyres inside were one-sided. The examiner said that the wheel bearings and upper lateral handlebars were in order. At the dealer I then had new winter tyres put on it before decrease. According to dealers they were also swollen. However, a passenger could find that about 80-100km of the car a bit z Is it possible to use an axle measurement? Or do you have any suggestions? Incidentally, the cover at the front of the ventilation nozzle probably clamps and does not open reliably. The dealer said that you only have to change 3 pieces from the “switch motor (attached)”. Does anyone know the problem? Thank you very much! Harry
