2002 A4 quattro: converters..approx 30 seconds..oil level..oil changed

This answer was rated:

I own an Audi 2002 A4 quattro 3.0 that has recently had both the catalyatic converters replaced. However, the check oil sensor has recently intermediately come on for approx 30 seconds and then goes off. I checked the oil level and it is fine (in fact, when the sensor came on, I had the oil changed).

Is this a sensor issue or could it be something else (re: oil pump)?

Hello and thank you for choosing Just Answer.


Usually it's the sensor that starts acting up. However I would not risk it, have an actual oil pressure test done to make sure there is enough pressure.

Could it be caused by the replacement of the cats (pinched wire,etc)?

No, catalytic converters are not in the area.

What is the longevity of an oil pump? The car has 115,000 miles? Is it a costly repair to replace?

There is no real time line for the oil pump. Typically they give out when the car is over 100000, but it doesn't have to and it can go out earlier.


As for the repair cost it is about 3.5 hours to replace it. That is about $350 for the labor cost.

It is a shame that many cars don't have an oil pressure gauge. This makes it hard to tell if there is a real issue.

Thats true, I believe they don't put oil gauges and fuel gauges into car is because of the leak possibility.

It's considered a safety hazard.

If the sensor is bad, how long of a job to replace it?

Not even an hour it's a very easy job to do. .8 hours to replace.
