It is E38 engine: 2000 740i.
1. Fuse is Good - Today, Dec 8, 2012, I check the fuse that is still good with 12.15 volts on the voltmeter.
2. Would you please point me to where is about the relay switch (in the fuse box in the engine compartment) and the 2nd Air Pump?
3. I look around the oil cover and could not find any hose is broken or disconnected.
Any help is greatly appreciated.
