Hi, I have recently bought A6 Avant 2.0 tdi SE Multitronic, 2013, 68,000 miles. It's a very nice car - quiet and smooth in comparison to my previous manual 2007 model - the auto transmission taking a bit of getting used to.
I have noticed that under moderate / hard acceleration there is an audible whirring sound (but not loud at all) coming (it sounds like) from driver side air vent. Sounds like a fan with something lightly catching in it. I can't replicate it when car is at standstill and rev the engine - it only occurs under acceleration. AC is off. Is this sound normal - I was not aware of it in my previous A6? Is it something I should worry about?
I have also noticed that when I turn my engine off I can hear the fan winding down and stopping afterwards - again I was not aware of this in previous A6 ...
Anyone any ideas - should I be concerned about either of these things?
Thanks.
