Hi all. Forgive me if this has been covered before. I have a 2010 1.5 dci. A few years ago i had a dpf clean (apparently 2 as it was so bad) costing £800+. Since then i have the two traction control lights on. There isn't any engine management lights and the car drives good. A few days ago it started to feel sluggish and after some searching i am lead to believe it could be a blockage in the small pipe (picture added). Aswell as needing a regen or possibly a dpf clean as i don't do a lot of motorway driving.
I don't hhave the money to take it to the garage so i want to attempt this myself (i'm not a novice, and have rebuilt and maintained many cars over the years)
My question is does anyone have any pictures of where the pipe is situated or any other tips.
Many thanks Sean

Yep thats the pipe it's at the back of the engine. It will need a good clean once you get it off. As it's blocked.

Thanks for the reply. With the help of a friend i did manage to locate said pipe and thoroughly cleaned it as it was completely blocked. After reinstalling i took it for a test drive. All the lights have now gone out but i got round the corner and lost all power. It idles but won't rev at all. I am at a complete loss as to what it could be.

Welcome to this forum.

Have you checked for error codes?

Issue resolved. After a few hours of scratching our heads, checking, checking and checking again that everything was in place and no wires etc had been disturbed we disconnected the maf sensor connection and it seemed to work properly.
Upon further inspection we found a piece of the filter had been sucked in which was blocking air.

Was yours loosing power when accelerating? At a total loss with my 2016 qq… this pipe was blocked had it changed but no difference atall really not sure what todo next as it’s not safe to drive …

Up until the blockage with the air filter it was running ok. It was more of an annoyance with the lights being on but i did feel a small loss of power the day before i sorted the pipe out. Maybe yours has a dpf blockage aswell. If you are capable i would do it yourself as the prices are ridiculous. I paid the best part of £1000 because it needed doing twice as it was "the worst they had seen"

My dpf is completely clear, garage even done a regen just incase but now I’ve had a computer plugged in when the car has jerked it came up a problem with the crank shaft position sensor as soon as it drove normal (lasts seconds) the code was clearing its self.. I’ve ordered a new sensor but can’t for the life of me find online where it is actually located on my car
