ok i have a jetta gli 1.8t with 66000 miles on it. and last week, my oil pressure light came on while driving, so i killed the engine and checked my oil real fast. seemed fine with what i could on the side of the road so i got home and changed out all my oil and filter. drove again and it came back on once the engine heated up and i was above 1500 RPMs. if i say under 1500, it does not come on. so this week, i dropped the oil pan and cleaned out some orange plastic pieces from what i assume is part of the dipstick. put it back together, and still came back on. i use mobil one full syn extended performance since i first bought the car and i am the only owner. any thoughts on what it is and please dont say the oil pump....make it something easier please hahaha

One troubling possibility is the dreaded 1.8T sludge problem. I had a similar issue recently and took my car to a sharp local mechanic. As I recall, he replaced the (internal) oil pickup screen, put several changes of oil through the engine and put me on a short oil change interval for a couple of changes.

As I understand the legend, heat soakback from turbo "cokes" ( i.e. cooks ) the oil which encourages sludge-goo to build up in the engine. The sludge starts blocking oil passages (like the pickup screen). Frequent oil changes are supposed to help. Running the engine hard (high turbo temps) and the suddenly shutting the car off (without spending some time at idle to let the turbo cool) is supposed to hurt. Consider the story hearsay as I am not a mechanic myself.

I will say, the good ones are worth what they charge. The hard part is finding a good one.

Don't ever overlook the possibility of a bad sensor. They rarely go bad but sometimes do. Is there oil in the rubber sleeve that goes over your low pressure sensor? Put a mech. oil pressure gauge on there and see what pressure you have. (un thread sensor and thread in mech. gauge in that port. If you don't have one, autozone, napa or whatever local parts store has them cheap with rubber line and fitting. Or have your local repair facility do an oil pressure check for you.
