Injectors....

Hello.

I've got a 2014 Superb 2.0 TDI which has a hesitation about 1500-2000rpm and also a strong smell of exhaust in the cabin.

I borrowed VCDS and from what I understand it uses UDS so I can't measure the injectors individually so had a look at he Advanced Measuring Blocks section.

These are the only injector measurements I could find (couldn't get the photo to upload)

Injector 1 rail pressure calibration point 1 -7.20

Point 2. -4.10

Point 3 -6.40

Injector 2 rail pressure calibration point 1. 4.65

Point 2 5.70

Pont 3. 4.55

Injector 3 rail pressure calibration point 1 2.85

Point 2. -1.75

Point 3 -0.30

Injector 4 rail pressure calibration point 1. -20.95

Point 2 5.30

Point 3 -8.55

Can anyone make sense of these readings? There is clearly a difference in the readings but am I looking at injector 1 and 4 being faulty or 2 and 3?

Any help is appreciated.
