Mine is a Bosch 0261230030, i might just take a punt on this been faulty and purchase one. I don't fancy sticking a multimeter in those pins to test it with the bike on!
Cheers for that, I've just ordered one. Hopefully this works and i don't have to start cutting into the wiring loom to find a break in the cable!
Bad News is that the sensor did'nt fix it. I started to carefully peel back the wires and all good up to where it goes into the main loom! Then i cut further into this and find a break on the brown/red near the head socket. I stripped the wires and made a temporary connection and the EML goes out. Time for some soldering and heat shrink, but its pretty tight around here.
