These articles discuss the Mass Air Flow sensors in the mk3, mk4, and mk5 VW TDI.

The mk4 MAF is problematic, so there is also a separate writeup on how to test and replace it.

Thanks for that!
I remember someone mentioning that they used to be $300, I guess they dropped the price to about $100ish dollars.

A direct link to vendors? Everyone should do that.

 

[chittychittybangbang]

Yeah, it makes the writeup that much more effective. A part number and clickable link.

 

[diesel guy]

Do that to every writeup.

 

[chittychittybangbang]

Sure, find the link and send it to me

Ther are so many writeups in the FAQ (1000 answered questions) that it takes a while to do them all.

I can appreciate your sources on this work.

Even though you did not ask to reference my work, I do not mind. The more TDI owners that can be helped, the better.

Come visit me over at Fred's place. www.tdiclub.com

The pic has a watermark with "bam bam dip" on it. Your writeup and others were very helpful in making it.

I hope that this site's FAQ is easy to navigate, it is designed so that every writeup can be accessed from the FAQ menu (1000 answered questions) within 3-4 clicks. Lots of how tos and other helpful info there.
