Hi, I'm having oil pressure problems with my MK4 VR6. I know that this can be an issue with high mileage (144k in my case). Had an oil change to a heavier grade oil. Oil warning light still comes on at times, always when the engine is warm (after being in stop/start traffic). Had the oil sensor replaced. Love the car and it has just passed its MOT with a couple of advisories so would like to keep it going if possible. Any ideas/advice re the oil pressure would be much appreciated. Oil levels are ok too. Thanks.
