    I had my car (2007 Audi A6 2.0tdi BRE) scanned using an official VCDS system and in particular the measuring blocks for the fuel injectors and the results were as follows.

    Group 13 Idle stabalization (Injector Quantity Deviation)
    -3.01 mg/str cyl 1
    2.99 mg/str cyl 2
    2.99 mg/str cyl 3
    -3.01 mg/str cyl 4

    The car went belly up a few weeks ago and was diagnosed by Audi as Diesel leeking into the engine oil via the injector seal. This then took the turbo seals out so I have replaced the injector seals and fitted a new turbo but now the car is running extremely rough at tick over and need to know if these values point to injector trouble.

    these readings are just on the edge of the parameters which suggests injectors
    i have had thse figures before but after a good dose of redex diesel they seem to equalize
    its worth a try

    Interesting, I have been told by some people that they should infact all be aroung 0.00 if running normal (at idle) and that the figures I have posted mean that injectors 2 & 3 are not working and that injectors 1 & 4 are working extra hard to compensate. It's all a bit confusing, still might be worth a good shot of Redex though, cheers
