My local mechanic had me buy one of these thinking that the airbag light I had on was due to the passenger side occupancy mat malfunction. I ordered this from the UK, paid $50USD + $15USD shipping for it. Turned out it was actually the airbag on the driver's side that needed replacing. So now I have this brand new emulator that's still sealed in the package and is not worth trying to return to the UK.
Works with E81, E82, E87, E88, E90, E91, E92, E93, E63, E64, E65, E66, X3-E83, X5-E53, X5-E70, X5-E83, X6-E71, Z4-E85, Z4-E86, Z4-E89
This is the exact item:
