Question about Volkswagen Cars & Trucks
Sometimes when driving the car keeps cutting out, it seems to happen when I press on the accelerator? and the oil light came on there a few mins ago too but the oil is at a good level as I just checked it?
Is the level too high-keeep withn up n low---too much pressure can strain rods n pistons-------may hav a failn fuel pump-du pressure test---also a worn torque converter in trans is factor----did u change plug wires and test ignition coil for resistence-----vacuum leaks in engine also--inspect hoses or listen for noises

Was the vehicle running when u checked the level?

This is not a known solution, but in general these cars suffer from voltage and current drops on electrical connections due to corrosion on contact surfaces. I cannot remember the number of times I have read about electrical problems on these cars, and the problem was usually solved by cleaning the electrical contacts or replacing a relay going bad (BTW, this car does use a lot of relays however I doubt there is one in the fuel gauge circuit).
Also, I have a spare gauge cluster for the 944 and when I look at it, there are some resistors on the "printed circuit" piece. If one of those were to lose tolerance, or burn open, it would no doubt have an effect on the accuracy of the circuit. I would check out that circuitry and test the resistor values as a last resort -- it is not likely the gauge itself if it is working at all. However, before doing that I would clean the electrical contacts thoroughly. I have not tried to gain access to the wiring harnesses for the gauge cluster while it is in the car, but I doubt it is possible. So, if you have exhausted all other ideas go to the Clark's Garage site for instructions on how to remove the dash, and just follow the portion that applies to removing the gauge cluster. Go to the local electronics hobbyist store, or online, and obtain a good contact cleaner and clean all of the electrical contacts while also looking for loose or broken wires. NOTE: Be careful and gentle dealing with the plastic connectors on these cars as they tend to be brittle and little tabs break off easily if man-handled. Go slow, be in the right frame of mind and use good lighting so that you can see what you are doing.

I had a similar problem with my 1986 300e , which got progressively worse until the car was no longer driveable, I changed out the fuel pump relay and the problem went away.

I had the same problem with my 2000 Sonata a couple of years ago. It was the crank sensor and once replaced, it solved the problem.

Its exactly the abs module! and its keeping the ecu from communicating with the rest of the car, when you remove the module your tac will come back alive and the oil light will turn off. There is way to trick the ecu to thinking the abs module is working but it involves taking out the module, it is fairly simple. My email address is firstname.lastname@example.org, email me, and I will give you pictures and instructions on what to do. Its really easy, your abs and break light will go off along with the beeping!

SOURCE: OIL PRESSUE LOW
At some point, your engine is registering low oil pressure and warning you the oil pressure is insufficient to lubricate the engine properly.
How does the engine know this? What causes it? Excellent questions. The engine 'knows' this because there is one or more sensors that read the oil pressure all the time. The sensors report to the computer which reports to you. They could be faulty. On the other hand, there could be times when oil pressure IS low. Your oil pump may be mal-functioning. Normally, I would expect the oil pump to either do its job properly or NOT do it properly but not act intermittently. It may warrant being checked by a professional. Another reason for this condition could be the oil itself, though you report you just had it changed. Presumably, whom ever did the change put in the proper oil grade, service and weight, recommended by GM.
Another thought, is this warning seen by you immediately after you start the car? If yes, it is normal for oil to take a second or two to build the proper pressure, particularly in cold weather. Where I am at, it is cold. Oil doesn't like to move when it is cold (like me) so it takes a bit of time to get up pressure (like me).
If this continues, you may want to have this problem looked at by a professional, as I said.
