The MAF Shop has a new addition: The Pierburg air mass sensor 7.22684.07.0 which fits most Mercedes CDI engines and works even as a replacement for a few Land Rover / Range Rover air mass meters.

Pierburg Airmass meter 7.22684.07 for €74.90

The offer contains next to the sensor also an installation kit with the needed but hard to find torx bits.

By the way, I found this PDF containing some general info about the MAF itself: Pierburg PI 0024
