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.

when i go into measuring blocks,how will i know which injectors not running as it should,thanks. how will i know which injectors ok?

 

[Uwe@Ross-Tech]

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.
