Just had low oil pressure warning light come on so parked car up straightaway. Quick scan with Carista came up with fault code P15ce. Car has plenty of oil and had consumption fix 6k ago.

Anyone know what this could be?

Waiting for AA for recovery.

Finally got home, car is starting and running fine and no sign of warning light!


Hopefully it is just a faulty sensor?

Warm it up until normal temperature, see if the warning comes on when the oil is hot and therefore thinner.

Is the coolant level OK and clean looking coolant?

Will try in the morning and check coolant? What could it be?

If it comes up with low oil pressure when the oil is thin it might be a genuine oil pressure problem caused by wear in a bearing. Changing the oil may help.

If there is oil in the coolant there may be coolant in the oil, this swells the oil filter and stops the oil flowing, making the oil pressure drop.

Oil was changed about 3k back using Millers Cfs fully synthetic. Would the bearings have not been replaced when I had the oil consumption fix approx 7k back.

Will have to check coolant in the daytime.

Thanks for the advice.

Coolant is fine.

Have decided to not move/start car. Will get Audi to pick up car and check it out. If they start it and break it not my problem.

Still going to cost me knowing Audi!
