There are a few nigs I have... one thing that I had to get used to was the steering on the vehicle, I find it simply too light. Coming from a power assisted steering to power steering you can really tell the difference.
The other is the electric parking brake, I was told that if the parking brake is on by driving off it will automatically come off by itself however it doesnt do that sometimes and I find I have to put the car into neutral again and then disengage the parking brake first.
Lastly, why the hell have Audi decided to go with a mechanical key in this day and age? I know theres an option to get keyless entry but I mean surely they could have made the electric key stock. Dont they do this on their A4's and up?
