I can’t justify the cost without a definite fix. It’s just one of those annoying issues.
I should add that I had the issue looked at when in warranty and they couldn’t find a fix
The £195 was just a diagnostic fee (Eastbourne Audi) if work was required it would incur further costs. As you say, normally happens after the car has been standing for a few days, but not always.
Did you ever find a fix for this as I have the same problem from new? (69 plate)
Audi say there is no update listed for my car, but if I did want to bring it in there would be a £195 diagnostic charge with no guarantee of a fix.
