    After reading something about plenum chambers and stuff on the post regarding smelly aircon & steamy windows, I had a touch of the fear.

    My last car was prone to plenum chambers flooding (horrific stories regarding drowned ECU's etc) so I thought that it would've been a thing of the past since moving onto the A4. Is it a general maintenance thing on these cars to clean out the plenums every now and then - especially in Autumn with all the dead leaves etc that can clog up and cause things to drown?
