Hi, we bought our first audi last week, an a4, b5 1.8. It has 115k on the clock and is a 98 reg car, has full service history and cam belt done at 96k, generally not too bad other than the exterior door trim needing replacing and the usual volume **** fault on the stereo.

However we have a problem that may be quite bad. My misses rand me this morning, it was raining so put the blowers on hot to de mist the windscreen, there was a burning smell and the screen misted up more rather than cleared.

Now i cant say in all honesty it is a burning smell but it is quite un pleasant, but it does stop smelling, its only for a few seconds after switching the fans to hot (there is no smell on cold). I have done some research and apparently a worn out cabin filter will smell like sweaty socks, i cant say that thats the smell either, i did check the filter though and it was put in upside down and well covered in crap, i bought another and replaced it but the smell is still there, like i say only for a few seconds after turning it to hot.

Any ideas?

Thanks in advance.

 

You probably have mold in the vents and ducts from the old filter. My old car had something similar and I bought and aerosol spray to get rid of it. You pull the trigger and put it in a car with the windows up and the climate control on recirculate and it fogs your whole car with a mist of alcohol.
