Anyone have any idea why I'm getting this one fault. I turn off the check engine light and it takes about 3 days to return.

could be your post cat O2 sensor or your MAF.

Is there a post for cleaning the MAF?

Default you can check the tech section or B5 FAQ. Really you need to get MAF

cleaner from your local auto parts store and then take the MAF out to clean it. If you have a K&N air filter I would remove it and go back to stock paper filter.

Default i thought the post-cat O2 had no effect on fueling?

so wouldn't it be pre-cat O2 & MAF are probable causes?

or a boost leak after the turbo?

Default A bad pre-cat O2 will typically make the car run lean. I think the post-cat

measures the efficiency of the cat. I could also be completely wrong.
