I've got an A4 B5 1.8T 2000. When the engine is cold, the oil level is right at the maximum level, but after a couple of hours of driving, the oil level dips below the minimum mark and the low oil warning light comes on. I've been doing Auto RX sludge treatment for a year now (I drive the car very little). Any insights?

So it is leaking, or it comes up after it cools down?

Park on Even ground

Run the car up to Temp

Shut the car off and wait about 5 minutes for things to settle

Check Oil Level


You might be seeing a light for Oil Pressure, not Oil Level.
