My 2006 A6 has been at the Audi dealer for a week now. Oil pressure light came on not long after an oil change. Car runs great and they have been at a loss. This morning they are checking the oil filter. One of the master mechanics has seen occasions where the oil filter will "suck up" a bit and trigger the oil pressure light.
