2002 audi a4 oil pressure light issue

could be either or both take to trans tech for test and reading of trans code

HI, you dont say what the sound is like, Have you checked the engine oil, this car as the PD engine fitted and only use good fully synthetic oils.it could have gone into limp mode for lots of reasons, go to a reputable repair centre and get the car checked out, good luck.

is this all mate.look for the oil light switch and over it is a rubber cover ,pull the cover back and you will see that it is full of oil ,clean the cover and fit a new switch,or just leave the cover off so it drip`s down engine .light will then be off

something has been left disconnected. look at the back of the head (remove the plastic cover on top of the engine, just there for looks) and make sure everything is hooked up. if not you need to return to this mechanic and have him correct the issue.

Hi there again

Sorry to hear you are still having problems.If you are going to change the pump I would certainly not recommend you do it yourself.If it is the V4 motor I am thinking of, you would need to get to it by removing the rear seat ,remove access panel , and pretty much play around in the gas for an hour or so to get it off in the first place.

What I did find was this on the net on a recall by Audi to replace 2002/03 model fuel pumps as noted below.

RE: 2002 Audi A4 Fuel Pump Change:


I just had my fuel pump changed out by the dealer. Here is what the letter said-

"Safety Recall JL 2003 year Audi A4 quattro with 1.8L Turbo or 3.0L engine and 2003 Model year Audi A6 with 3.0L engine"
The fuel pump on some affected vehicles may contain a carbon brush set that is susceptible to premature wear.

On invoice it says-

JL12 Install fuel delivery unit and sealing washer.
1 8E0-919-133-G Washer
1 8E0-906-087-P Fuel Pump

No charge for unit or install. Just call them up and give the vin number to see if your car is affected. On the other note of your code error '1&3 misfire',try and have it re-set (it might be an old error)and see if it comes back. Hope this helps ,and I will research your problem further with pleasure if need more help.

CHANGE IT

quickly i would check oil level first.then i would check for oil leaks could be leaking oil. have oil pressure tested.make sure oil pump pressure is good.

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.

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.

The car has entered into fail safe mode. It wil not allow the engine to rev high but allows you only to get to a mechanic or to get some oil into the engine. What's the level like? Is there any trace of leakeage?
