1990 Audi Coupe Quattro Q&A

1990 Audi Coupe Quattro Question: where does cabin air filter located?

and how can I replace it? -
Answer 1
I see one listed (with picture) on www.rockauto.com but I do not see instructions, location or price of parts in any information I look up. I don't think it actually has one. Some cars have them behind the glove box but if there is actually one fitted in your car it may be in the engine compartment under the wiper arm panel. -
Answer 2
the first audi in usa to use a cabin filter was the 96 a4, you don't have one. -
