I've been getting these three codes when I plug in the diagnostic checker; VAF, MAF, and Fuel Air Metering. My VW is hesitating and sputters, it also likes to completely shut off every once in a while as I'm coming to a stop or stopped at a light. A year ago I put in a new MAF sensor meter and still the check engine light came on. Next I changed the oxygen sensors and just changed the MAF sensor meter again. Has anyone had this issue and know how to fix it?

Brake cleaner will RUIN a maf. They make an appropriate cleaning agent.

If you have an ohmmeter check the voltages on the maf plug and make sure the ecu is sending the right info.

I don't have an ohmmeter. What are they? What do you mean by checking the voltage and ecu sending the right info? What does ECU stand for?

how do I run a search to find out what the parameter should be? Do you mean an internet search?

Yea internet search. Best bet is to go over to the forums at www.vwvortex.com and search there. Odds to you finding an answer are pretty high

How do I measure what I am getting? Also, vwvortex doesn't have a SEARCH field. Anywhere else you know of that may have give me the answer?

awesome, thanks for all your help and explanation.
Wish I knew the numbers off the top of my head!

If the voltage turns out to be ok it may just be the maf. Where did you get your last one?

From PGautoparts online. Item # 071906461B | 0280218017. Is there really much of a difference between the Bosch MAF and and OEM MAF?
