I have swapped my BT rev counter for ST rev counter as I am now running coil packs on my P8.
Strange problem, it still reads 1/2 what it should be, but when I turn the engine off with the keys the engine does not stop, but the rev counter appears to work ok!
I can take the keys out and it still runs! I can not drive it like this as the steering lock would come on!

If I take the multi connector out of the light cluster the engine stops.

Isoun there a wire I need to disconnect from the rev cter or multi plug?

Any ideas?
