Rattling/ ticking

[Brees20]

My A3 has this rattling/ ticking noise for 10-15seconds at start up, in 2 cylinder mode and at low rev acceleration. Has anyone else found this issue? My cars only covered 35,000 Miles and Audi colchester apparently haven't had anyone else complain about this issue to them before. It had the 1.5tfsi engine.

What a bizarre response from your garage. I suggest you find a garage that might be interested in investigating the fault and earning some money, preferably not an Audi dealer.
