Vacuum Leak

<< < (2/4) > >>

Dan_FR:
I think 032 are the fuel trims. Don't need the engine running just ignition on. What intake do you have and what software/map?

scopes:
Revo intake with a custom tune from a tunner over here in N.Ireland.

I will go and try the fuel trims, if i remember the last time i checked 032.. 0.8%

scopes:
032 vcds

Lambda regulation
      -0.7%                      -                2.0%
Lamda(idle)                                Lambda (partial)
self-adaptation                             self-adaptation

scopes:
Any Idea's ?

Dan_FR:
Sorry, missed this yesterday - was home time!

Trims don't indicate a leak. Certainly nothing large enough to cause your issues. It may be worth posting this on the Facebook page 'TFSI Tuning' if you have FB. Lots of clever people on there. Only thing i could suggest off hand is checking every reading with VCDS and making sure everything reads normal. The only other thing that springs to mind is the Throttlebody
