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.

How do know if you have m54 or m56?
Steve G December 28, 2015
It doesnt matter,you just need to know if its a 2.5l or a 3.0l
Seneca D December 28, 2015
Im not sure but M54 is the engine type of production range for BMW X3 and X5 (mine is 2004 X5 3.0i). You need to call the dealership with your Vin number or search Google for your car model and year made.
Patrick N December 29, 2015
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!

open the hood, look at the engine covers with the white stripes running from you to the windshield. if the oil filler cap is between the stripes you have a M54. The m56 is off to the left in front of the white striped cover.
