My 1997 328ic has had water in the secondary air pump for the past year. I get water draining out the snorkel into the front engine compartment. When i replaced the seconary air pump my mech scolded me for driving underwater but...i hadn't! Now I suspect it is condensation from the AC as I dont see anything dripping on the pavement with the AC on. New mechanic tried to "blow it out" but its been cold and I haven't had the AC on - Anyone with similar problem?????
