I took delivery of a 35 TFSI black edition at the weekend. I was out this afternoon and parked on a gravel car park. Came back and started the engine to be greeted with a tyre pressure warning. I had a quick look at the tyres and all looked ok so reset the values and drove home cautiously. I've just checked them and they are all set differently. 1 was 41.5, and lowest was 38. I'll change them to 39 at the front and 36 at the back as per the recommendation in the door. This is my first Audi so wanted to know if the pressure indicator is a bit sensitive or is it pretty reliable? I have a bit of tyre pressure OCD so hopefully it's pretty stable.
