reason I said don`t drive it it happened to me the 1st day I drove the x of the lot ,oil indicator light came on and the engine stalled and threw a code saying camshaft sensor fault, took it an indy that only works on bmws ,checked the oil right away and did an oil filter change immediately ,the oil filter was plugged solid with thick oil and he said that was the problem and if I kept driving it the engine would of starved with oil not flowing and it would have been a disaster. all good now though no more oil light comming on. so don`t ignore this light.
