Hi, I have an issue with the "DPF regen duration" (left DTC info at work) on this car, found split in upper DPF pressure sensor pipe so cut it back and refitted tubing. Live data when driving hard shows maximum pressure difference of 17 kPa and I checked it with a pressure gauge fitted to the upper pipe and on snap throttle I got about 1.5 psi so it looks like the cat-DPF is fairly clear, and the car drives fine.

My question is regarding the temperature sensor fitted to the cat-DPF - with the engine stone cold, IDS live data says 100 deg. C and Verus says 140 deg. C. Either way it's not at ambient temperature of around 6 deg. C. And when driving normally its behaviour is consistent at around 450 deg. C.
Driving it in 3rd gear at around 3000rpm it reached a maximum of 649 deg. C. ( using Verus ).

I am assuming that the temperature sensor should be showing ambient correctly and not the 100-140 as given above, and is the 100-140 temperature shift added to the actual reading causing the regen to be cut short due to the temperature being too high and logging the "regen duration" dtc?

Thanks, Martin.
