Air mass meter for BMW M5

An error indicating that the air mass meter is faulty, which is quite common for the E39 M5, is twice as bad for a the driver of that M5.
Why? The M5 has two air intake hoses it also needs two air mass meters.

Though this is the engine of a E60, you can see how it has two airmassmeters

Often only one of the airmass meters is actually faulty though. You can save some money by just buying one air mass meter and trying out which one is really broken.

In case boths units really are faulty, the MAF Shop charges you for shipping only once – regardless of how many units you order.
