Hi all, hope you can help. I have a 2012 A7 sline Quattro, bit of a high Mile’r at 80000. It doesn’t seem to like cold starts and makes a sounds lie the bottom is going to drop out when you take off, take of also drags a bit, it’s like a hissing tapitty type sound!! Does anyone know a fix?

It drives fine when warm, which takes an age.

Hello Peter,

As much as you have provided information on the issue, it would be very difficult to diagnose the problem without assessing the car. 

With regard to ‘... warm, which takes an age’ - this would suggest thermostat problems, and would entail renewing it.

Kind regards,

Gareth.
