Sludge could be causing the light to come on. most likely the sensor came on because you went a certain mileage without changing your oil.

My 2006 2.0 tdi passat keeps going in limp mode and saying emissions workshop. Can anybody help


hi mate, my 55 plate passat did the same before major problems happened. first turbo went then the oil pressure light came on and the car went into limp mode. before its too late for you and a costly bill can you do the following.
check if your car has a recall for the injector problems which vw are replacing under warenty.
second thing the guy who repaired my turbo told me that these cares have a major fault which caused the turbo to go. the fault is the oil pump failure you must adress this issue as you can get a lot of info on the discussion forms.
my car started with the same problem as you have described the pd engines have a design fault with the oil pump and shaft. this is common causing your turbo to go then the car will start showing oil pressure low please stop engine. educate your self via the forms and act quickly befor you end up with massive bills.
i hope this has helped. trust me vw know about this design fault.you need to change your chain driven oil pump to the new gear driven system which vw have modified. all vag cars have the same problems be it audi skoda vw . my car had the same problem as you have said .started off with emissions then turbo failed thats when i started to investigate this problem . the pd engines was designed by some rookie at vw.

Oil level and oil temperature are normal. Oil


Same here....I soon had the same problem after changing the oil..Found out after many tests and research that auto parts stores cross reference a lot of audi oil filters to the vw counterparts..Which do fit audi,but are shorter and lack the oil capacity to feed the engine.Then the pressure light pops on!!!! make sure the larger/longer oe type is installed.If your not sure buy it from audi its not much more than the napa brand.

I have a 98 audi a4 1.8 t was told its has low and high pressure regulators and the low pressure isnt working right


Need to know what sort of pressure was being discussed, and what the symptoms are.
There is no low pressure regulator I know of in the fuel, oil, or anything else, except perhaps if it has turbo charging.
So unless you can be more specific, I don't think they were telling you correctly.

Oil pressure gauge reads low all the time, oil level is good and oil is clean. pressure warning light does not come on when engine running, appears to working normally. Engine running normally A4 1800...


Jim, you are going to have to look at the oil pressure sensor. It may be bad or it may just have a loose wire or bad wire. This sensor picks up the oil pressure and activates your light.

Audi:oil light came on, car won't start now...oil is showing full???


Check oil pressure sensor, if it is not working it will put your car in "Limp Mode" to protect the motor. If the sensor is working check the oil pump, it could have failed.

Can 2001 a4 quattro low oil light be reset


No, it goes out when the oil level is read to be correct. If you have the right amount of oil in the car, your pressure sensor is bad or you have oil sludge blocking the pickup tube at the oil pump. Run some Seafoam in the oil for 100 miles and then change the oil and filter (or if the pressure light stays on, add half a can of Seafoam and idle it for 20 minutes before changing the oil). Repeat 2-3 times and see if it goes away. If not, change the pressure sensor (on the oil cooler - the aluminum block the filter screws onto). If this still isn't a fix, you need a desludging kit from www.ecstuning.com. If THAT doesn't fix it, drop the oil pan and change the pickup tube and filter screen, clean out the pan, and repeat the Seafoam treatment.

OIL SENSOR LIGHT ON 2001 Audi 2.8liter


It could simply be maybe the person changing your oil never reset the light? or you have a oil pressure sensor leaking or not working.
most of the time its someone never reset the oil change light. even before it goes on it goes by mileage, so maybe it didnt go off yet cause you cnahged it a tad early.so noone even tried to reset it.

I guess you could have an oil pressure problem, but thats going the extreme route.. but if nothing else shows that could be a problem.

2002 audi a4 oil light issue


There are potentially two different problems here.
1. A fault with the actual oil pressure.
2. An electrical fault with the switching circuit.

If you are confident the problem is not with the oil pressure, disconnect the wiring from the switch for a period of time. If the light still comes on periodically the fault must be with the wiring circuit shorting to earth. There will be no fire hazard to this approach as the voltage will drop over dash lamp.

However if the problem is with the oil supply system, the danger with this approach is you are potentially unaware of a serious problem

Such as the oil filter collapsed or the oil pressure release spring could be jammed open/closed which would cause the engine to not have the correct operating pressure.
