My wife's 2010 A1 1.4 TFSI (50,000mls) has recently started making a crunching noise when changing gear up from 1st to 2nd. Anyone else had this issue? I'm worried that this could be a very expensive problem. The engine also rattles for a couple of seconds when starting up from cold. It's got a full service history so oil changes have been done ok. I'm wondering whether to move it on and get her something else?
