What code are you getting. It may not even be MAF related.

 

The read says low voltage from MAF.

 

What is the voltage? Is the voltage low at idle or when you increase throttle? Better yet, hook up the scanner and see what you get for a volume reading. Also check the voltage coming form the hot connector wire, (forgot which wire offhand). Make sure it reads just shy of 5 volts.

You should take a reading BEFORE cleaning and AFTER so you can see a change. I have never used brake cleaner; only GUNK, carb cleaner and electronic spray cleaner. All brought the sensor back to new like readings.

 

Clean the terminals on the maf plug and the maf sensor, then buy "Stabilant 22A" from the nearest VW/Audi dealer and apply it to the terminals, this may help as it enhances the contacts in the connection. A code of this sort could be caused by corrosion or a poor connection.

 

I wouldn't use carburetor cleaner, that stuff will dissolve paint or the plastic in the film. Too harsh.

 

Well after new MAF and a code reset with my new ODB II scanner, back on the road...woot.

This weekend I will experiment with the right types of cleaner and see what happens with the old MAF.

Thanks everyone for your input.
