Hi all,
Can anyone tell me where the G450 "Exhaust Pressure Sensor 1" is on a 2008 Passat TDi?

I have found the one near the firewall and accessible from the top of the engine bay, but I have also heard some suggestion there is one lower down (and requires the car to be raised and stone guards removed to access).

Since the error code I am trying to remedy makes the point of "Exhaust Pressure Sensor 1" it leads me to believe there may be a second and I want to be sure I change the correct one.

Thanks!
