Why is the oil pressure light on in my Audi A3?

I recently noticed that the oil pressure light on my Audi A3 has been coming on intermittently while driving. What could be causing this and how can I fix it?

The most common cause for an oil pressure light coming on is low levels of oil. Check your oil level and top off if necessary. If the light continues to come on, it could indicate a leak or other issue that should be checked by a mechanic.

Another possible cause could be a faulty oil pressure sensor. This is a relatively easy and inexpensive fix, but should still be checked by a professional.
