2002 AUDI A4 OIL LIGHT COMES ON AND CHECK ENGINE LIGHT.

Hello.
A week ago the oil light on my 02 a4 quattro 1.8 came on.oil level is fine and also check engine light came on.my buddy hooked it up to the computer and i got the code ''system too lean,bank 1''.he cleared the codes and as soon as the oil light comes on again,i get same code.what could it be?not to help the situation,my ''smart'' wife forgets to do an ail change on the damn thing.hasnt gotten one in 18k miles.could that have anything to do with the light being on?

Keep in mind a year ago i had the same problem and it was one of the fuel injectors,replaced that,but since i had driven the car for 60 miles after the light came on,i also had to replace the timing chain tensioner.

The code system too lean, is caused by the bank 1 02 sensor, as far as the oil light coming on with oil ok,I would say the oil sending unit. Have those checked or replaced. Without testing this and that, it's hard to say what's causing it.

The dealer has to "reflash" your 02 sensor light. On some Audi's, the dealer has to reset the O2 code first and if it comes on again, then they will need to replace the cat convertors.

Oil level problem with 2005 Audi A6 3.0 TDI Diesel Quattro


My 2005 A4 3.0 convertible audi is not a diesel, but I had a similar experience with a low oil signal going on and after checking the oil, which was sufficient, and replacing the dipstick, the light did not come back on until a subsequent trip. The light usualIy went on when I was close to the needing an oil change. I've had the car, a used one, for about two years, and the oil light minimum signal started behaving like yours early. About a week ago the oil pressure warning light came on. I don't know if there's a relationship, but if there is be careful. Audis of our vintage have a problem with sludge build up that damages the oil pump, which is a costly item. If you drive the car with low oil pressure you may seriously/fatally damage the car. I don't know if the sludge, if that's what you have, can be cleaned out, but I'd do it if it can be. My mechanic advised me to trade the car to a dealer rather than fix it. Hope you have better luck!

2000 Audi A4 quattro with abrupt gear shifting & low oil pressure


I hope that you had the proper weight oil installed, at your oil change. If your oil is up to the proper level, and it's rattling ,this is VERY bad. White smoke usually means steam in the exhaust, and that means a blown head gasket. Check your coolant level. I wouldn't drive it anymore......until someone knowledgeable can diagnose it!!!!!

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.
