I have an ABT air filter installed in my A4 which is nearing its 30k service. My question is: should I have the dealer clean the filter or should I do it myself (put the stock filter back when I take it in for service)? Also, what's the best way to clean it? I believe the 30k service involves replacement of the filter (correct me if I'm wrong).<br>TIA

I don't know if your dealer is like mine, but I'd rather do it myself..just make sure they don't take it out and toss it! I have the RamAir filter from Wetterauer, which is also about to get cleaned tomorrow. Don't know if the Abt is like the Ram, but I got a bottle of cleaning solution and a bottle of "filter impregnating" fluid to return its filtering characteristics after the cleaning. Maybe contact the Abt dealer.<p>Rich<br>'98 2.8Q sport<br>

If anything they might throw it away by accident.<br>Mention to the service advisor that you have an<br>aftermarket air filter and you will probably be safe.<p>Steve S.<br>97 2.8QM<br>

God I love Australia. Sure we pay through the nose for a lot of things, but at least my dealer cleans my K&N filter for me...but then he installed it for me!!!! :-) <p>Graham
