Default Turbo problems

My 1.6HDi seems to be suffering a bit of a glitch with its turbo. 99% of the time its fine but suddenly i lose power and the car goes into safe mode with no turbo but no engine management light. Stop car, turn off then back on and all is fine again though it seems to be doing it more recentley.

There also seems to be a lot of soot on and around the top of the turbo and im wondering if it could be connected?

Turbo is 28k miles old btw.

Soot around the top of the turbo is from the clamp that connects the particle filter to the turbo not being replaced after being removed. Tighten it up the best you can.
Get a diagnostic check done and post the codes up.

What sensors connected and which disconnected , is it going into limpmode in a similar number of miles or under load ie going up slight incline with full load at around 70/80 mph.

Yes it did actually do it on full load up hills.

Afaik all sensors are still connected. Oh and its still regening. My remapper said he might need to find another 407 same year and engine and copy its eprom or something or other in order to completely wipe regens off and ive told him about you and alering a switch at the beginning of the map but to no avail.

Disconnect the temp sensor on the Particle filter casing only.

look for the two pipes coming out of the FAP , follow the bottom one to the brown sensor and unclip it , a bit tricky with one hand , it doesn`t just pull apart you have to unclip it and pull at same time , look ar the sensor at the top left of your radiator to see what i mean its the DPF sensor .
