Hello

Firstly thank you to the many others who have posted on this topic,it's been a great help getting to where I am so far.

Briefly, 30miles from Calais, cruise control failed, red engine light and slightly reduced power. Manual intimated could be driven, so drove to ferry, other than power loss all ok. (Perhaps not wise, but stranded in France with small kids not ideal so lesser of two evils maybe)

Post ferry, no drive, lots of black smoke from exhaust.

Under bonnet find turbo intake pipe sheared. Roadside recovery said it was common, taped it up but error P047B persisted, diagnosed failed boost pressure sensor. Recovered home, fun trip on the lorry :D

I've replaced the intake pipe and the sensor. ODB reader also showed P0471, so I did the bike wire and wd40 job, that has cleared and so has red check engine light.

Despite changing the sensor, I still have the P047B error, and also P0380 (glow plugs?)

Will start and run, but is sluggish when revved and will die at idle at times. I can run at 20mph in 2nd with full gas (did so far about 2 mins), this was accompanied by a reasonable amount of white smoke, no warning lights,just those above codes.

So that's the story.

My questions are

1) is it reasonable to assume the white smoke is dpf related, and I need to try to run her in?
2) why would the P047B not clear with a new sensor?

I'm erring towards calling a dpf cleaning specialist, but would appreciate any input.

Thanks!
