Why is my Audi A6's oil pressure warning light on?

I just noticed that the oil pressure warning light on my Audi A6 is on. What could be causing this and what should I do about it?

The most common reason for this warning light to come on is low oil pressure. Check your oil levels and top up if necessary. If the light does not go off, it could indicate a more serious issue and you should take your car to a mechanic for further diagnosis.

Another possible cause for the oil pressure warning light to come on is a faulty oil pressure sensor. This is a relatively simple and inexpensive repair, but should still be taken care of as soon as possible to avoid any potential damage to your engine.
