Hi all. I'm new to this forum. (waves) I have one of the first A4 2.0 TDi S Lines (Reg Jan 2005) The Climate control is pants ! It;s OK when it's very hot or very cold outside, but the rest of the time It's noisy and blows a gale through the centre vents as soon as ambient cabil temp is reached - it seems worse when the external temp is about 14 degrees. To be fair, Audi technical are looking at it for me, but after a year haven't acheved much. Do any of you experts have any experience of this problem ?
