As simple as a maf sensor?...

Hi all,

I've been having issues with my 2.0 tfsi. Well I've had lots of issues.. Balance shaft failure etc...

The car has been irratic revving and had irratic performance too, as well as really poor fuel consumption, I changed the clutch switch and the pcv and neither of them made a difference, checked for leaks, couldn't find anything.

Today I decided to unplug the maf sensor and low and behold it's feels so much better! No revving issues and performance has improved. Could it really be that simple?!
 
Sounds like it may well be a culprit! Do you have VCDS - what are your fuel trims?
