DPF problem - won't regen

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,

I have a 2012 Qashqai+2 1.4 Diesel .

MY DPF was well and truly blocked (causing the Engine Management light to come on).

So I bought a new DPF and had my local garage (whom I have used for years) fit it.

It was fine for about a month and then the light came on again.  The 
garage looked at it and sure enough the code was DPF.  He tried to 
initiate a regen via his computer and it went 3/4 of the way through and
 then stopped with Regen Failed.  So he manually cleaned out the DPF, 
refitted it and it was fine for about another month until the light came
 on again.

I might add that when this happens the car is a struggle to drive - It 
is lacking power and it can just about hold 60mph but feels like it's 
"Pulling back".

My mechanic is at a loss as to what is causing this (and what caused a brand new DPF to block after a month).

Does anyone have any ideas at all please ?

Thank you in advance for any help.
