Today I had cruise control retro-fitted at an Audi dealer. All seemed to go well, and I picked the car up at the end of the day so was too late to take back. Tested the cruise control out and it all seemed fine, but I noticed that the steering wheel was off-centre (slightly to the left) when driving straight whereas before it was perfectly dead ahead (and tracked straight too). It seems the car now pulls to the right when I let go of the wheel, as though the steering wheel itself wants to self-centre?? I realise the steering wheel has had to come off to fit the cruise control so assumed the wheel just needs to turning to the right "1-spline", the main concern is the car now pulling to the right; do these cars have some kind of "positive centre" steering? It is as though the steering is self-centering based on the actual steering wheel so that means the car is driving slightly to the right if that makes sense (have to hold the wheel slightly left to drive straight). Normally if the steering wheel has been put on at the wrong angle it wouldn't affect the tracking of the car, it would just be off-centre. Going to take the car back tomorrow to reset the wheel but just concerned as to why it's pulling whereas it didn't before.
