I've got a question regarding the US version
of the 2000 M5. Are there any differences
between the US version and the european version? I'm specially interested in the
engine / engine control system and the exhaust system.
Actually, I have a Euro M5 as a test vehicle and it works with my OBD-II scan tool. It may not light the MIL like a US version will, but the architecture is there.
Also, the Euro version does have four O2 sensors. Again, I have the car to prove it.
With such low production numbers and such a high price, I think that BMW may just have the same emission system on all M5s. Just an assumption based on my auto engineering experience. Plus everything I've investigated on the Euro M5 checks out with the official US M5 serive documentation I have.
