no doesnt bother me mate, low water,low oil,low brake pad,low fuel,low screenwash.

i have just traced through the curcuit diagram and your right there doesnt seem to be anything that should effect the ignition... im 99% sure that when i saw it disconected i reconnected it and the car would not start again until i disconnected it.

like i said i had a serious problem with the car initially, which was electrical and i couldnt work it out what it was so a garage sorted it and touch wood it hasent let me down since.
