Im new to all this, but other are helping me with my problems so i shall try.

possible reasons (i think)
1- BSI unit fault
2- Instrument panel fault
3- crankcase/flywheel sensor

and all associated fuses and wiring connected to all/ether of the above.

Unfortunately i have no idea how to test which is to blame. hopefully someone will be along soon to help.
