    You can't do a dribble test with a scan-tool.

    What you may want to look at are the measuring blocks (I think 013 and 014) which show the balance between injectors at idle.

    Just go to Group 013 and tell us what you have there.

    Post your ECU's part number too.

    ECU: 038 906 019 FP
    0 281 010 729



    These are what i got (cyl 1) -0.75 (cyl 2) -0.42 (cyl 3) 0.66 (cyl 4) 0.52

    These figure obviously increase/decrease slightly (taken on idle)

    Nothing wrong with those values -- i.e. they don't point at a problem with any particular injector. In fact, they're quite good. Spec is between -2.8 and +2.8.
