Where is the oil pressure sensor located? The oil sensor light came up on my friends 05 A4. Thanks!

Does the oil need to be drained before replacing it? Thanks for the info BTW

yes, it sits up in the pan, it is a level/condition sensor. The oil gets the sensor gummed up and dirty over time, especially with oil that doesn't get changed when it is supposed to.
