Question about 2003 Volkswagen Passat
Just had an oil change
My 2003 1.8L Passat at 62K indicated Oil Pressure, Stop Engine. I had been low on oil for longer than I realized, though the car didn't indicate to me anything. I added a quart 5-40 synthetic as usual, and about 300 miles mid way on a road trip is when the warning lit up!
I had been to the dealer last year and there was a mention of sludge developing in these cars. They suggested I bring it in to remove sludge but life got busy, and it never happened. Evidently this model Passat is notorious for this oil sludge problem.
My Passat needed a new oil pump $800 later half way between destination and home. Luckily I was in a town with a 30 VW mechanic who was very good. The sludge (carbon deposits) had blocked pump pickup. Oil level was good. The computer didn't show anything, but the oil pressure test discovered PSI went down when RPM's went up. Not good.
This problem is very serious as it has ruined engines. I guess I was lucky in the fact that nothing else was damaged. So you may look into this build up. It sounds terribly familiar.
