    comin home from work today, noticed a loud tap at low revs when setting off, been to garage and they say my dog bone mount has had it. could this cause the following fault ode to be thrown P0328, as I have have checked wiring to the sensors and swapped the knock sensors around, as well as retorquing both. any ideas would be appreciated, thanks. also checked the voltages on vagcom and cylinder 1 and 2 seem high compared to 3 and 4. had injectors ultrasoniced, new plugs, only thing I haven't had is new coilpacks. I have no noticeable misfire at all neither

    replace the wiring with screened cable right back to the ECU. Seen this a few times

    just looked on net now and apparently the thin black wire in the casing should go to the plug somehow, is this correct as I noticed mine was halfway up the loom

    There are 3 wires and a screen from memory but the sensor only requires 2 wires...
