Thanks... definitely worth a go!
Though I have another interesting lead - My Exhaust gas temperatures seems very strange - When the car is off, it always reads 104c, and generally stays around the 200c mark while driving which seems a bit low I think!?

Curious if this 104c when engine off is a common quirk, or a strong indication that my sensor is off.  Do these numbers seem unusual based on what you've seen from your car? (image attached)

Just checked mine, stone cold engine, engine off is 108 degrees, it will go up depending on speed and revs between 108 degrees and 300 degrees maybe a little more, I would say yours is normal, it will go up to high 500s to low 600s when regeneration takes place.

Thanks! This is a relief...I read that removing these is very challenging at best.

I'm going to have a go at replacing the pressure sensor and see how things go from there.
