I have a new A3, 3 weeks old and it's back in the garage. When car is stationary on take off, either using home assist or handbrake sticks badly and really slow to release, so much so that it cuts out: am now holding the car with foot brake. Service garage was shown issue on day of car drop off but cannot replicate the issue, diagnostics isn't showing up anything and they want to give me back the car. I don't know what my options are, I don't trust the car now. I had an A3 before with no reliability issues. The Audi service garage can't find the problem - anyone else having similar issues ? Could do with some advice
