Engine oil warning light

Question edited for clarity.
Question moved to model category.

Let's assume you mean engine oil. You also need to change the oil filter as well. You will need a jack, axle stands, an oil catch pan and a container to store the old oil until you can take it to your Community Recycling Centre, a set of wrenches and an oil filter wrench. As Larry states, it is much better to go to Jiffy Lube, with no fuss, no mess, in and out in 15 minutes.

NEED CODE FAULTS AND THE ECUS THAT THEY COME ON!!

Time to have a mechanic diagnose it...judging by your description...do you race the vehicle??? is it well Maintained??? Did you buy it new??? have you had the timing belt, and tensioners replaced??? If the timing belt gave way, and there were no funny noises, that means your car has a "non interference" engine, which is a very good thing...find a mechanic that you, or some of your friends trust, and let him/her take a look at it...you might need to leave it for a while...good luck...

The warning light is for oil pressure.

First check the dipstick, make sure there's enough oil in the engine.
If so, then there may be a problem with the oil filter, when was it last changed.
It could be the sender, is the connection good and clean.
Finally the oil pump filter may be blocked, or possibly the oil pump has failed.

You're going to need to visually inspect for leaks and if no external leaks are evident I suspect your head gaskets are leaking again - check oil for coolant in oil - it will look milky

I would suggest that you scan the computer for fault codes. There are different sensors that control ignition and fuel and any one of these sensors can cause the car to stall and refuse to start. The crankshaft positioning sensor could be the cause if it has failed completely. The check engine light may be burned out , therefore no warning lights.

It sounds as if you seized the motor due to lack of oil ( very easy to prevent too bad you never checked the oil level )

Absolutely - the 1.8T engine is known for sludging issues. If they diagnosed oil sludge then your engine is covered no matter the mileage. The oil sludge builds up in the 1.8T no matter how well cared for it is, and the sludge can block the oil pickup screen on the oil pump (it's an extremely fine mesh), causing oil starvation and taking out the engine in the process.

Go to www.audiforums.com and do a search there for "oil sludge" and the information will come up. You can learn all about it there. But if your engine has the sludging, and you have receipts proving the oil was changed at the proper intervals, you will get a new engine free of charge - one of the members there is an Audi technician and I remember him posting that he'd changed out a 180k mile engine under warranty due to sludge.

Sounds like carbon build-up in the cylinders. Take it and have it put on a machine called a "Motor-Vac"

have you tried cleaning out the throttle body as i had a similar problem and this worked
