Hey I'm looking for at bit of help I've had my oil pressure light coming on during engine start and then goes out after a couple of seconds, that's the last you see of it until you restart the engine. I was told that the oil pressure switch was broken, i changed the switch a couple of days ago and found that the pressure light behaves differently now. It comes on only when i go over 2000 revs and goes out when i go below 2000 revs. For a test i decided to put in the old pressure switch back in to see what happens and found that it behaved the same as the new pressure switch going on over 2000 revs. oh my engine is a 1.9 TD T Reg Can any one help me please has any one experienced this before thanks.
