Injectors condition diagnose

[wpaul]

Has anyone here have had injectors
checked via vag-com? ( without dismantling anything )
Heard there's such an option and was just wondering how accurate that might be.

Yes you can check the delivery on them, it's in measuring blocks i think, it was accurate on mine.

Are you sure it was done with a vag-com ? or rather an oscilloscope ?

 

[steveb]

I did it with VCDS (VAG.com) is this the sort of report you are looking for ?
