Hello forum,
Lately my car has started weirdly shaking/rattling(When idiling) until motor gets warm(Around 80+ degrees). Used my friends VCDS, and got these results with the scanner.
Can someone smarter confirm my suspicion?
This picture was taken, when motor was warm.

Looks like injector 2 is worn and about out of the range so the ECU is compensating. If you mouse hover on the value VCDS will tell you the range.

Go to ENGINE > Measuring Blocks. go to block 005 and evaluate the IQ. It should be around 2.5-4.0 If it's too low it will cause the engine to shudder at idle.
