2007 A6 2.0TDI Injector VCDS values

[steve.b83]

Hi all,
My 2007 A6 Avant 2.0TDI has had a misfire for a while (more noticeable when accelerating, settles down when at a steady speed), my garage thought it was an injector on its way out but wasn't 100% as they didn't test it, they just wanted to replace all the injectors.

I have checked the injector values on VCDS but need some advice as to what the values say

Inj. 1 Inj. 2 Inj. 3 Inj. 4
IDLE = -0.59 -0.56 0.85 0.33
1500RPM = -0.68 -0.52 0.42 0.78
2000RPM = -0.78 -0.45 0.38 0.82

If anyone could shed any light on these values I would appreciate it.
Steve

Number 3 is suspicious but diagnosing faulty PD injectors is fraught, it is not as if they are cheap or easy to replace.
