Okay, so my mk4 gti 1.8 sits at 253K miles and runs like a dream. Good compression all round. But recently after a drive a low oil pressure light came on. Thought nothing of it, topped here up with oil, and kept driving. Then the light became sporatic. The light would only come on when the engine was as loads of over 10%. At Idle, no light. At 3k rpm cruising on the highway, no light. Any time I asked the engine for acceleration the light would come on. I dont think its the oil pick up becasue I think the damage would be much more noticeable and catastophic. I would like some feedback and help on the matter. ALSO, the light never comes on when the engine is cold. Oil cooler problems?
