well i checked da oil and the level was full and when the light came on i panicked and top it up again so was def full i drove it bout 5miles and light came on again. so i parked it outside my mates left her cool down and then drove it 30miles home and was fine. hence confused.x

could be a faulty sensor as you said, but usually if the light comes on its either low engine oil level (which its not) or low pressure in the engine - hows the car running?

normally she aint running any different. even when the oil light comes on she dont lose any power she runs the same. x

low oil pressure doesn't necessarily mean low oil!

replacing the switch will be made easier by removing the Cat/downpipe from the turbo.

but it might not be the switch, the only sure fire way would be to fit an aftermarket oil pressure gauge and see what pressure you've actually got.

check the picture, the switch is circled, the downpipe is the pipe in front of it. if you have a catalytic converter then there will be a large cast iron cannister in place of that pipe coming off the turbo in the picture, making getting at the switch (again, circled in the pic) difficult

:)

will it damage the car driving around with the light on then? oh i thought he could change it in about half an hour. he said it was straight forward and seeing he works in a jap garage down here i believed him x

it is fairly straightforward for a mechanic.

it most certainly will damage the car with light on if the sender is accurate, hence why i suggested an auxilary oil pressure gauge to confirm if the pressure is indeed low or not.
