Injection quantity deviation with VCDS

[SR71]

Hello Guys,

I would like to know how to recognize a bad injector with VCDS.
The car (VW Crafter 2.5 TDI) smokes at idle speed.

Hi.
The correction of your injectors is within the norm. The second injector looks worst, but it falls within the norm. The standard for different engines is -2 to +2 or -2,8 to +2.8. Big corrections at + 2.0-2.99 indicate that the injector "pours" fuel.
