Great product for a great price
I bought this MAF after hearing from my local mechanic that the repair would cost over $650.... If you are debating whether or not to do this repair yourself, do it yourself. It is so simple, there are videos everywhere, and this product works great. My service engine light turned off itself after a few hours of driving too. Great product and I highly recommend it.

BEST ANSWER: Hello! Patrick is correct you can always call BMW with the VIN number and they can tell you. Also you should be able to look on the engine block itself and there will be a tag that shows the engine ID. Thank you and have a great day!
