2003 passat 1.8t oil light popped on. I was having repairs done from an accident that wasn't my fault so I assumed that it was from that. Insurance company shop mechanic told me it was a sludging problem very popular with this vehicle type. I went ahaead and performed a flush and changed the filter and oil (Valvoline MAX LIFE SAE5w-30 synthetic). Car ran fine yesterday. Today on my way to work anytime I pushed it above 2000 RPMs the car would make a howling noise and have little pick up. Do I need to perform a more serious flush? I have BG Quick Clean 109 but was hesitant to use it and used a more generic brand. Please help.

Re: 2003 passat oil pressure/sludging
Vw group all say engine should be flushed at every service but owners are normally cheapskates(like me) and dont get it done(i do my own oil changes )your running problem has nothing to do with oil/filter/flush.get a computer diagnostic asap its easier than guessing...

Oh no sorry to hear that. You did the right thing by stopping. If you have the 1.8 turbo engine this happens too often. The oil pressure sending unit could be the problem, but most likely it is the oil pump. This engine has sludge buildup problem & VW is aware of it, so there is hope. VW issued this update awhile back....
Passat owners. 1998 through 2004:
VW has just made a warranty extension covering certain oil sludge repairs on
It is now covered for 8 years unlimited mileage and will reimburse for
repairs made because of this problem. See your local dealer or contact VOA for
This light is an indicator that you have oil sludge in your engine and you should stop driving your vehicle and get it checked out right away. By continuing to drive the vehicle can cause further damage to your vehicle.
when did you have the oil changed last??? if the oil is sludge you will have to remove the oil pan, cleanthe screen pickup. i would also recommend removing the valve cover and cleaning the top end, then run a high detergent oil
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.
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!
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.
