What do these codes mean?

[t0m]

Can't find the Knock Control Regulation Limit one on ross tech site. Someone please help...

2 Faults Found:
17733 - Knock-Control: Cylinder 1: Regulation Limit Exceeded
P1325 - 35-10 - - - Intermittent
16716 - Knock Sensor 2 (G66): Signal too Low
P0332 - 35-10 - - - Intermittent

Every site where I've found that 1st code just tells me what it is I want to know causes/fix if possible thanks.

As both are intermittent codes, clear them and see if they return. For more information on the 16716 code, see the Ross-Tech Wiki:

Cheers Bruce. I cleared them at the weekend and will be scanning the car again in the next couple of evenings when I have time.

The 16716 code keeps coming back for about 2 months even when I clear it, but the top one is new.

Any other symptoms? Did this start showing after you had the engine tuned/mapped? It could be an issue that you need to take up with your tuner....

The car was mapped by AmD Essex back in February. Straight to a stage 2 code from OEM map.

These codes have appeared since June I think. The car feels a bit rough? Car starts fine, no dash warning lights. Just these faults when I scan it. But the Knock Sensor 1 intermittent code doesn't come back straight away. It could take a few drives or a week for it to re-appear.

The fact that it feels a bit rough may be telling. The knock sensor may be legitimately sensing a knock. You might want to start looking at the fuel trims and such to see if they are pushing toward an out of spec condition that might be leading to the knock problem.

Ahh I see. Thanks for that mate, I'll have a read!
Hope it's not too serious
