Brain Trust,
I am getting code P2251-13 - Oxygen sensor negative current control - circuit open. Bank 1 - Sensor 1.
I know it is generally on the right side of the engine(with cyl 1), but the workshop manual does not show the location for a single turbo variant...

Any help - always appreciated!

Found a diagram of where the O2 Sensor it.

Even though it says Bank 1 Sensor 1 - which would normally be on the same side as Cylinder 1...
There is only 1 set of O2 Sensors on the TD6 and it is behind the left side of the engine.

Thanks for the update. At least you're on the right track.

Just looking again at your diagram JD. I think it's a twin turbo engine, it has 2 air boxes and apparently that's the give away. Maybe that makes a difference? 🤔

Yes - I see that now... I have the single turbo variant - but I still think that there are no O2 Sensors on the right side (Passenger in most of the world)

I will keep looking though!
