Aqua-Phobic Audi (3)

[Andy Schor]

I cleaned the HVAC drain out a few weeks ago.  That was when I first 
discovered the footwell was wet, and C.E.L. would stay on while the 
car was running.  The codes have been cleared and there is now plastic 
covering the ECU and connector.  

Sunday night I parked facing downhill, it rained hard and the floor got wet.
Last night I parked facing uphill and the floor stayed dry.  Yes it
actually 
rained heavily here in Pittsburgh two nights in a row.  Anyway, the 
recirc flap sounds like a good place to start.

Thanks,
Andy Schor
