Hi all,

MY00 turbo with quite a few mods over the years (always done properly and remapped whenever anything has been changed).
LambdaLink and KnockLink fitted many years ago and have always been fine but last week the LEDs on the LambdaLink stopped illuminating (power LED is still on though). Car is running lumpy and using tons of fuel so I suspected lambda sensor knackered.

CEL then started coming on briefly and very intermittently - stored code is 22, which I wasn't expecting.

I know code 22 is knock sensor faulty but just before I replace the sensor, given that LambdaLink is not working, should I be looking elsewhere? Could the 2 things be related or is it just coincidence?? There are no codes stored for Lambda sensor which I'm surprised at. Could it be faulty MAF sensor?

Cheers,
Steve
