2003 B6 Avant 2.0 FSI engine problems

[mikeallington]

Hi,

The engine on my Avant 2.0 FSI has started running a bit rough on tick over and does not always like to start first time.
The car runs much better at speed once the revs are up above 2000RPM.
I have borrowed a friends Ross Tech diagnostic tool and it reads the following faults:

16698 - Misfire(s) detected single (unspecified) cylinder
P0314 -001 - Intermittent
16712 - Knock Sensor 1 (G61)
P0328 -001- Signal too high - intermittent
17441 - Sensor for NOx (G295)
P1033 - 002 - Signal too low
17912 - Intake air system
P1504 - 008 - Leak detected

Any ideas or help would be greatly appreciated!

I have the same car, but not the same faults...

Have you checked through the Ross-Tech website? Unfortunately only one fault code is listed in the Wiki section...

16698 - Misfire(s) detected single (unspecified) cylinder
P0314 -001 - Intermittent

16712 - Knock Sensor 1 (G61)
P0328 -001- Signal too high - intermittent
16712/P0328/000808 - Ross-Tech Wiki


17441 - Sensor for NOx (G295)
P1033 - 002 - Signal too low

17912 - Intake air system
P1504 - 008 - Leak detected

Hi,

Thanks for the link to the Ross-Tech site, very useful!
I have got a little further with the fault but still not cured it.
I cleared the fault and not all of them have come back.
The car still rocks on idle but i think this is to do with the engine mounts?
It was suggested if the engine mounts are no good this could affect the knock sensor?
The engine mounts are defo suspoect because the engine does rock around a bit and you can feel movement through the gear stick.
Any thought??

Thanks, Mike
