Recently had my cooling fan go into overdrive every time I turned on my car. Wasn't sure why, but I knew I had to drive to work. Also noticed my climate control would push cool air, but not any hot air. In fact it pushed cool air even when it was set to heat. After a few days I got an engine temp hot warning (yellow: drive slowly to your BMW service station), then a red engine temp warning (engine hot, pull over when safe), and finally a red warning reading "engine overheating, pull over and stop immediately or engine will be damaged".
Had a mechanic friend plug in his snap-on tools diagnostic computer and it pulled up two errors:
2E82 electric water pump, switch off
2E81 Electric water pump, speed difference
He said although he's done a little work on BMW's he won't be able to help due to it being from Germany (I thought all were made in Germany but apparently some are made in the States? I know this one shipped from Germany because I wanted some additional optional upgrades and had to wait 6 months for it to be built and sent over). His shop also deals primarily with domestics and they don't have manuals for BMW's.
He suggested I have another friend who's a mechanic work on it, and he may know some people that can work on it.
Question: Are there really going to be differences in parts between american and german made BMW's? What part number is the water pump if that's the problem and I need to replace it?
Also, he said it might just be the fuse having blown. Is that possible? I have about 90k kilometers on this vehicle.
Thanks for all your help!
