Hi all... Had my 2007 A3 Sportback about 1 month now.... But since we have had the very cold weather 9 times out of ten when i do a cold start, ie 1st thing in the morning i get a squel from the engine like a belt slipping or something it last for a few seconds untill the revs settle(excuse me im not technical) .... I have taken it back now twice to the Dealer and they say cant find anything wrong ???? Am I being fussy or is it just because how cold the weather is i am getting this problem ?? Cheers..
