I needto find out whats going on with the car as you have all read by now the vacuum is reading down along with the boost pressure but the car feels ok apart from the idle problem.
How do i use vag com to take a reading what my car is doing with the maf, pressure etc and what am i looking for, i dont have a registered version of the software by the way

ah you getting close to being the link master lol
cheers rich

If you want to log boost (I assume you do after reading about N75 problems) log group "011", MAF is "003" :wink:
-
is it 115 to check boost or is that charge control. I need to check boost and vacuum
-
your limited with what you can log with the freeware version, you cant log 115, you can log intake pressure which is 011
-
AGU you can't log boost i believe due to the lack of a MAP sensor
-
Got my full version of vag com and tried to read blocks 113 but it said its a invalid block ? why would it do that

its 115 isn't it
unfortunately still no good if its an AGU as you can't log boost
also not all the blocks are used - thing to do is log one and the click through them all until you get to the one you want

i did a run on the charge pressure control and the readings are this, this was a third gear foot to the floor up to the redline

Put those figures into an excel format table. They'll be easier to read!
I think you have to compare the specified with the actual amount and yours start together and then they fall off.
From here (difference between second and 4th column):
