Well... I've done some checking... It appears that this grommet is one that they only used on the e53, and they've discontinued it. Realoem shows it being used on practically every BMW from that...

Not the expansion valve. Some of the "fancier" cars started doing variable volume type stuff so that you would have the same ammount of pumping at idle as you do on the interstate. That way the AC...

There is definitely not an electric valve. It would have to be mechanical. If it's no easier than replacing the compressor, then I'll replace the compressor. Maybe, after I get this one out, I'll...

When the car is running, you should have a minimum of 13.4V on the battery. I like 14, but it shortens the life of the battery. If you don't have more than 13V, the battery isn't charging.

My 2001 needs a head gasket, so I fixed it today by buying a 2006. The new one is a minor basket case and I got it cheap because I was the only one who could make it run and drive. It has three keys....

Right now, the leak is small. I'm going to try the Blue Devil head gasket sealer first. Uncle Tony's Garage did an episode on it. It uses waterglass to get into the leak, then solidify. The results...
