Yes, they did have that bulletin & they replaced the following: Hose Assembly, Shield & Pump. This was after they found water intrusion in the air pump. Last week when I went, they said there was nothing wrong with the parts they installed, and they said "the vehicle ran a self test, and has passed last 4 tests, no problem found at the current time". So I just can't understand why I'm still having this problem!!!!!!!!!! Should I try to bring it to a different dealership?
