Hey all,

I've been running round for a few days now with the 'Borrowed' MAF.  big improvement- back up to 51-54 mpg now, seems like the old ( 1 month old!) one was faulty when the revs rose over 1500. must have definately been over fuelling higher up the rev range!

Funny though,  the VAG technician that downloaded the car said they was no faults whatsoever with the old maf, and that was what his computer said-  just go's to show that they are infallable!

Regards and thanks for your help

John

The MAF has to fail in a big way to throw up a fault code. There is a test you can do but it involves taking the car are out for a run with VAGCOM connected.

what do you need to test the MAF yourself i'm guessing a laptop running the VAGCOM software, and some sort of cable, what cable do you need and how expensive are they?

looks like they are readily available on ebay:-

@ under £15 i'm tempted to get one just to see what mines doing and have a snoop around, plus it will come in handy if i attempt the cruise mod down the line.

do yo need a licensed version to test the MAF?
