Morning both-

Thanks for the update on what you have done Nat. Was the gear wheel part stripped?

Yes- one of the teeth had broken off- its the classic problem with resetting the odometer while moving I think- this was a blight of the previous owner though. I tried one of the £10 kits off ebay but the gear was too small (diameter, the teeth count was correct). Had to buy one from Germany for £25!!

I have even found that the tightness of the 2 screws on the stepping motor can be problematic

I wouldn't even know where to begin with this!!

power is still getting to the speedo so that only leaves the signal

Agreed. I have redone the connection to the diff sensor in the past and have checked it recently using an Arduino while driving the car so I know that it is fine.
The symptom of me smacking the dashboard which causes it to come back to life suggets that it is something in the cluster / board itself regarding the signal - but it is hard to isolate when the problem is intermittent- I've tried my best to check as many of the blue plastic traces as possible for continuity and all seem fine! Losing my mind!
