Question about 2003 Volkswagen Passat

2003 VW Passat Malfunction Indicator Lamp on

2 weeks ago my Passat, while on a road trip, lights up ''oil pressure and stop engine''. Luckily I found a reputable mechanic who knows VW pretty exclusively. This yr car has a notorious ''oil sludge'' problem apparently and it clogged the oil from the pump so I needed a new oil pump. No other damage occurred, luckily. Car returned fine. Fast forward to today and letting someone borrow car. Upon return, I notice the MIL is on. Apparently the borrower noticed it came on maybe 15 miles prior to returning car. Though it may not be related, I am concerned that more expensive repairs may be in my immediate future. Any info on whether this newest illumination is related to the oil pump fiasco?

I have a 2003 Passat GLX V6 and i havent been experiencing this issue, however from my experience with VW, the early 2000 models of the passat that have a 1.8T 4 cylinder engine have a major issue with what has been deemed "oil sludge" you have to be careful with this engine oil wise and make sure to get the oil changed every 3,500 - 4,500 miles and make sure you get the full synthetic oils for it and the proper filters :-) the turbo that is on this model heats up the oil to extreme temperatures and if not serviced regularly you will have problems.... i hope this helps! i would have someone check it again for this issue... hopefully you get to it before it becomes costly!

You should perform an oil pressure test and see if the engine is producing oil pressure within specification. If it is, the lifters may quiet down over time.

Need to change the oil pressure sqitch on a vw passat


Hi before you do an oil change try seafoam in the engine oil. this can sometimes fix the problems you are having, I used seafoam in engine oil and fuel and breather line and ran engine for 100 miles, but don't run hard, and its cleaned all the sump and oil veins in the engine, as checked with a scope looking though the oil sump plug. it did a really good job, my engine is a bit older than yours 1994. oil sensor is at the bottom of the engine on the sump. pressure sensor is above the oil filter it has a single wire conection

2003 VW Passat "Oil Press, Turn Off Engine" and "STOP" Light


I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.

Oil pressure stop motor


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.
