I took My A-4 (2006, 145k miles) in for a routine oil change. After I got it back the Oil Pressure Light and warning sound kept coming on consistently. The sensor was replaced but still comes on.
Can't get the oil pressure indicator to go off or stop sounding.
Tried new sensor and upping the oil viscosity. After that it didn't come on as
much but it seems to at low speeds or intermittently. This was from 2
different mechanics.
