Hi all, having trouble with a Octy 2 2.0 16VALVE TDI which has developed a diesel knock when reved there are no faults logged and the fuel has been checked for contamination all checks are ok. The only possible error i have is read block 13 this measurement has been taken at 90 degrees C.

Display group 13

Measured values

-0.09 mg/H

-1.29 mg/H

0.31 mg/H

0.16 mg/H

The vehicle runs on all 4 cylinders and does not seem to be missfireing.

Sorry the engine type is a 2.0 16 Valve TDI.

Diesel Knock?

What sort of revs?

It could be the DMF failing, or a duffed injector or a number of things.

I'm afraid I've no idea what that channel is so can't help there.
