Well, spoke too soon I guess
At work right now, went out to my car to get some paperwork and there had been a heavy downpour about half past seven...low and behold, the area under the speaker was soaked again.
I really thought after driving through all that heavy rain earlier today and the door carpet remained bone dry, that the problem was solved. Seems not.
Found a garage on-line that services Porsche/Audi here in Little Rock, I guess I'm gonna have to take it down to them and see if they can find the cause.
Cheers, Gord.
