Fuel injection time deviation... What does it mean???

[Derek99B]

From my VCDS

CXEB 150120 Miles engine cold to 70DegC tickover around 10 minutes.

IDE12085 Fuel injection time deviation: cylinder 1 12 us
IDE12086 Fuel injection time deviation: cylinder 2 -75 us
IDE12087 Fuel injection time deviation: cylinder 3 32 us
IDE12088 Fuel injection time deviation: cylinder 4 32 us

Have I got a problem???
Is injector 2 faulty???
Is this the reason foir excessive soot on the DPF ???
Thanks in anticipation.

It’s pretty normal that some of them are positive and some negative. The overall sum of them is close to zero and they should all converge to zero with more rpm.

For comparison, see mine in VW T6 Custom PID codes for DPF

I don’t know if your values are exceptional though.

Hi
Thanks. I'll check it at 70mph later today.

No need to take risks for this - parked and engine running, just flooring the pedal for couple of secs is fine. The range of my graph was just 6 seconds!
