Hi all picked my big bumper 16valver tonight. She needs a few things doing buit what do u expect on a 110 thousand mile mk2 she s just had the head gasket done and top end rebuild. Hpow ever when the car starts up and is running both the water and oil light come on on the dash board?? I ve been advised that its either a sensor or two and the sytem needs flushing any ideas ?? THANKS
