    Hey guys for a while now on vag.com my car has brought up a knock sensor code saying signal to high or something similar.

    This has been the case for the past 3 years so I dont think and hope it can not be anything serious.

    I have ordered a green plugged sensor but I also notice there is a blue plugged one as well. Does anyone have any experience with similar faults and have any info?

    I maybe should have ordered both sensors and just replaced them both?

    i'd imagine with a knock sensor fault the ecu will retard the timing a bit to keep everything safe...

    Yeah I do sometimes drive along at a steady 70 for a long time and if I put the foot down the car does not respond as well. Is like the car is then just a n/a 1.8 or something.

    Would this be the case because of a sensor fault?

    I dont ever get a check engine light.

    i replaced both of mines theres a Green sensor and a blue sensor cost £70 for both from eurocarparts. PITA to fit as there under the intake mani and the connectors are under the coolant tank!
