my warning light came on today.

checked the pressures and there isnt a problem.

cant get the light to go out.

anyone had this problem before.

Presumably you have held the dash button in for several seconds to reset it ? If you have not driven it since the light came on try driving it a few hundred metres/yards then try resetting it.

i held the button in for a while.

the light flashed off for a split second and came straight back on.

will try resetting it tomorrow morning and report back

you can't reset it with the engine running, turn the key to position 1 and then hold the button down for about 10-20 secs and it will go off, make sure you have checked the tyre pressures though.
