Chris this advice was spot on....
Checked the bulb first .... Not the fault but when I took the sender unit out of my tank ... Bingo the wire had been disconected from the solder tag.
Fired up a soldering Iron and sloved the issue... Saved me a few hundred quid... for about 1 hours simple DIY.
Once again thank you...
So if you get a 8000 rpm fault code check the sender unit out inside the tank...
