car 2001 A4 1.8T (AWM) Tip
The CEL comes on rarly only when the car is sill cool, and you give enough gas to try to merge.
The person that had the car before me had K&N air filter, which I replaced with OEM Audi filter.
The car's requested/actual boost get close to 2200 mbar from block 115 so I am guessing that it's chipped... ?
From Block 30 I get x11 and x10 where x varies from 0 to 1 at idle and full temp, so my guess would be that oxugen sensors might be faulty.
But on the other hand the MAF readings are a bit low too (I think)
So I am having a hard time deciding if the MAF is DEAD or the O2 sensors..
Any help will be greatly appreciated !!!

I am going to make an attempt at cleaning it, soking it in 99% alcohol.
I already tried spraying it with circuit cleaner but no change.
