Hi, so I have had my first problem with my car after owning for 2 weeks now. Got in the car and it started ok, then I thought I would try and lock the car with the key button while the car was still running to try and warm the car up, this did not work so I turned the car off and then locked it. after about 10 minutes I returned unlocked the car and tried to start it, firstly it didn't recognisied the key saying put it near the center console where the key sign is. I tried several times and it then worked, but the car would not start the engine , I tried and tried and gave up calling audi assist. The guy came out plugged his laptop into the ecu and found several error codes which he cleared and then went about to see if there where any new downloads for the car which there wasn't . He has logged it into the system which apparently is sent back to Audi who look at it to see if this has happened before on other cars . Basically it was a software problem maybe caused by me trying to lock the doors while the car was still running. BMW have a system where the car can be warmed up before you enter the car without unlocking any doors, my mate has it on his 5 series. Great little feature to have in this cold snap we are having, shame on Audi not having this feature on the new A6. Just wondered if any one else having this problem with there car.
