There are two different LMM (Mass Air Flow Sensor) models from Pierburg for the T4 TDI.

1. LMS 7.18221.51.0 replaces 7.18221.01.0.
2. LMS 7.18221.58.0 replaces 7.18221.08.0.

I still have the LMM with the old connector (two-row).
My original VW chassis number is 074 906 461.
What is the difference between the two models?
Which one should I order?

Best regards,

Unfortunately, the image is heavily compressed, but my Periburg exhaust system for a Golf 3 TDI 90 hp (1Z) is the top one on your list, based on the VW part numbers you mentioned.

Yep, that's him.
Can the 7.18221.08.0 be converted to a ....01.0 model, or can the connectors be rewired?
The ...08.0 costs much less.

Best regards,
