1992 Jetta Ecodiesel that has recently been flashing the low oil pressure light when driving, not at idle. It did this a year or so back and I replaced the sensor near the oil filter but has started again recently and somewhat randomly. I’ll have a few minutes to an hour of it not blinking then a a few days of it on frequently. Is there a chance the oil pump on these cars goes bad or most likely sludge in the pickup tube? I’d love to address this problem in a couple weeks but the buzzer is ridiculous, can the buzzer be disabled?
