1998 A4 2.8 V6
Bought car used with 94,000 miles. Haven't even driven 2500 miles. Had to replace Throttle Body and still wouldn't run. Towed to another shop to replace transmission. Now oil light comes on only at high speeds on the highway. Just replaced oil pressure switch. Light still comes on. Oil pressure test done. PSI was 18. Mechanic said it may need an Oil Temperature Switch. Transmission mechanic thought that oil pump could be going out. Any ideas, I need advice quick? Thanks, Maryann

I have had the same oil/sludge problems reported here. I changed the oil and used synthetic oil and it was good for about 8K miles. It started again, I had about 5K since the last oil change. Just changed the oil again hoping it would solve the problem.

10 miles after the oil change, the car died. Appears to be the timing belt as the engine turns over but the valves aren't moving (I should be able to see movement in the cam through the oil filler cap, right?). The car made no noise at all when this happened, it just quit. I'm hoping that's a good sign that there isn't any engine damage.

Can anyone tell me how I can check the valves train without tearing the engine down?

Could this be related to the oil problem like the valve train seizing causing timing belt failure?(belt was replace 30K miles ago)

Also, does the oil pickup replacement cure the oul sludge problem?

I bought a used VW Passat 1.8 T 3 yrs back. The dealer scheduled a checkup with vw dealers, They checked and ok the car. Now since then 32 time the MIL light has turened on, showing the 4th engine is misfiring and a coil need to be replaced. Did that, then the emchanic told me that the oil which the precision tunes were putting in is wrong and it has triggered the RED OIL PRESSURE ENGINE LIGHT and STOP sign coming on all of a sudden while driving. Though no engine sounds, so got the oil changed, clean the whole system as it was coagualting in there. 2 days later, light comes on again, was told the sensor need to be changed as these sensors are bad in VW & AUDI both. Changed the sensor today and not even driving for a min, and the light came on again, with STOP sign on, and blinking oil sign..... Does anyone know whats going on? Haveto take the car back to the shop in an hour.


Just got recall today for that check dealer

If you're having this problem, don't disconnect the guage and think it's okay. You need to have the oil pan pulled and the sludge cleaned from the pan and the oil pickup screen.

I actually replaced the oil pump an pickup screen. Cost me $800 including labor but finally, after struggling with the for most of a year and doing major engine damage, it's right.

This is definite problem, I am in the process of replacing the oil pickup tube on a 2001 Volkswagen Passat 1.8T with ~150,000 miles. The oil light came on periodically and with heat and time it came on more and more frequently, the old sensor fell apart taking it off and I assumed that it was the problem. Wrong, I replaced the oil pressure sensor and immediately the light was back on. The next step was screw in a mechanical guage in place of the oil pressure sensor. I found about 15lbs of pressure @ idle or 750rpms and then as the engine speed was increased the pressure went down and was about 12lbs at 2000rpm. This is where the oil sensor must have at least 20+ pounds for the oil light to stay off. I tried engine flushes but that only made things worse. I even tried BG which is used by VW to try and clean the engine up when the sluge becomes an issue. When I finally got to this pain of oil pan off, I found the strainer soooo! clogged you could hardly blow thru it. Yes, it is a very small screen and if caught early the parts to do it yourself should not be in excess of $100 using factory parts.

I have just repaired a 97 18T passat engine with the same problem. Theturbo engine has a ridiculously small oil pump inlet screen, 1 inch in diameter. Any sign of any sludge or rubbish in the sump is sucked up and blocks the screen. Only need small amount to block screen, starve the pump and bring on the light. VW knows about the problem because they sell an upgraded pump inlet screen assembly for $700. I fixed the problem by cutting off the screen and welding a larger screen onto the pipe with a much larger inlet area. A small amount of sludge is now not going to affect the function of the pump. Problem has now gone away.
What size screen did you weld onto the tube and where did you get the screen?

You are all going about it the wrong way! i purchased a 2002 gls 1.8T recently with 70,000 miles on it ! i replaced the water pump and belt tensioner and also the clutch fan assembly through germanautoparts.com ! Then after driving it for just 5 miles the stop low oil pressure light came on! i got it home, and took the pan off which is a real ball ache because a lot of the front end has to come off! The solution to this problem is not to replace the sensors but the oil pickup instead! it has an extremely small filter on the pick up and clogs very easily! i took mine out and welded on a larger one roughly 3 inches in diameter from a gmc truck and put it back in and its been a dream ever since! whilst your there clean out the gunk in the engine and the pan and then flush the engine with the old filter still on then fill it with synthetic and put a new filter on! Run it on your drive/garage for about 20 minutes at various rpms and see what happens! once satisfied rebuild the front bumper etc and done!

Hi Jason, do you have any step by step instructions for remove the oil pan on passat 2000 1.8T, I have the same problem, thinking of dropping the oil pan myself and weld a bigger screen on to the pump.
Thanks

I urgently advice you take it into an Audi dealer to check the oil pressure. It happened to me, I was told its ok, but it was not .
It has now cost me 3000 to repair the engine damage caused by engine oil starvation.......... but the car was full of oil.... the sludge blocking the pick up strainer prevented oil from getting to the engine.

I bought a 2004 Audi a4 1.8 turbo on Sat, Test drove it, inspected whole of car, nothing obviously wrong, Full main dealer Service History. Car had even just had a basic service inc oil filter and renewal of oil (fully synthetic) 3 days before. Then ion way home while driving oil light started flashing, thought I'd stop at next garage and get some more oil, then engine started to sound a bit roar and a l tittle rattly So pulled the car over asap on hard shoulder, Whilst pulling over i noticed car wouldn't go above 3,500 RPM no matter what and when pressing accelerator harder some smoke cam out of exhaust? AA picked me up and said it was possibly oil pump, residue and then the turbo? Oil was in the pipe leading to the turbo?

Why don't Audi just admit failure here, and help us as it was my first Audi, and already i feel like never buying one again. Any clues as to what really has happened here sounds just like the above.

Anyone had any luck going to Audi? Awaiting repair bill!:(

2010-03-07 21:29 - Just resolved this problem with a SIMPLE FIX. Yes, coking in the oil pickup strainer screen was the problem, starving the oil pump and engine of oil.

Yes, I was getting the STOP light, and low oil pressure, and it was REAL. I could not go over 50 mph form more then 15 min without this occurring.

I bought a replacement pickup tube/screen and went to pull the pan and replace it I discovered that VW had built the car around the stinking oil pan. So my next solution was to get a self tapping oil drain plug (or rubber nipple one would work also), then drill a hole directly under the strainer screen the pre tap size of the drain plug I purchased. This provided me direct access to the pickup screen. So then I cleaned out the screen, with Gumout, a brush and air gun then rinsed the oil pan out with Gumout. Plug up the hole with the new oil plug, refill the oil. Whammo problem fixed. I have put just over 2000 high speed 75 mph+ highway miles on the car with no incidents. I hope this helps someone.

WTF! I have bad luck with cars and I thought this 04 VW Passat was one of the best cars I've ever purchased. Woe to me! I've had it less than a year and already had a few issues costing me a grand. NOW THIS OIL PRESSURE CRAP! When is enough enough?
Ill call the dealer and see what they say about a recall and repairs. Anyone wanna buy a VW Passat?
