SOURCE: oil pressure warning light on my audi a4 2005

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?

Is a pressure converting element on the block. Can be leak or shot. Or wire harnes problem worst case. If leak you see dripping oil mostly. Had that 2 times on a car.

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 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.

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!!!!!

Check the oil pressure wire attached to the gauge usually in the engine compartment. Dirt can interfere with the signal causing a short which will give you the symptoms you describe. Hope this helps

Replaced oil sensor light still comes on

MAY---May-be you really have low oil pressure.. The way this sensor works is when you turn off the engine it closes to ground.. and when you start the engine.. the oil pressure opens it and the light goes out.. SO.. if the wire going to it is grounded out somewhere between the sensor and the dash board the light will stay on.. 3 choices.. 1. bad sensor (even though you replaced it) 2. wire is shorted to ground.. remove wire from sensor while engine is running.. light should go out. 3. you actually have really low oil presure. next.. after you have exuasted #1-2. you can remove sensor and install a real oil pressure guage and see what the pressure really is.. If you have very low or no oil pressure..1. Check oil level.(probably should have done this first) 2.pull oil pan and replace oil pump.. while you are there check a main bearing and a rod bearing for wear.. worn out bearings will cause low oil pressure. If you have good oil pressure install the pressure guage permanetly and forget about light.

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.

The oil light comes on at times and goes off as the rpms go up. What can be done about the light?

Maybe your engine is idling too slowly, If the revs are below say 700rpm the low pressure warning light could come on especially when the engine is hot.. If the idle speed is ok try a heavier grade of oil in the engine. Next try a new oil pressure sensor. It's got to be one of these things. Check the engine running temperature . An over-hot engine will cause the oil light to come on too.

Oil light

Sounds like a sensor. you may have hit a good bump or something knocking the sensor for oil level or pressure loose, it may also just be dirty so you first have to locate it and i'll admit on a Audi I ahve no idea where it would be, But it seems like just a sensor

Oil light comes on

Hi, this is an oil pump issue. i recommend replacing this device and the oil screen as well.

The oil pump is a device that distributes the oil throughout the engine. at high rpm's the demand on this device increases dramatically and, if it is malfunctioning in any way, this high demand can not be met and the needed lubrication will be shorted, therefore, tripping the oil light. Most damaged oil pumps can produce enough pressure during low idles but, when the rpm's are increased, the malfunctioning pump will fail to meet expectations. this will cause low pressure and inadequate oil flow. this can also damage the block in time if not corrected.

I would do a quick oil level check to make sure of proper oil level. if the oil level is proper, you will need to replace the oil pump asap. if the oil level is low(1-2qts low), just add to full mark and, run a test drive. if the light illuminates once more, this will confirm oil pump failure and it will need to be replaced.

Remember to replace the oil screen as well.

Please rate and god bless:)

You're low on oil - the Audi dipstick isn't the most accurate thing out there. Add a quart and see what happens.
