BMW Bosch AMM Up for sale is a Good working 0 280 212 010   1 718 521 9 AMM.  - This was removed from a very clean, recently crash-damaged euro model 750il.  This car was someones baby!  Nice shape air flow meter.

I will warranty it for 30 days after purchase. I bad AMM can cause a lean running condition, loopy idle, no start, runs but has no power, random stalling, excess smoke, pinging, or any other strange running conditions. This is CHEAP compared to new or rebuilt, even at wholesale prices! Genuine BOSCH used unit.  This is NOT a cheap aftermarket china made unit.  This is GERMAN!
