VW polo TDI 1.6 - 2012 VW Polo 1.6 tdi rough running - ozz1e

Hi All, Mrs has a 2012 polo diesel 1.6 TDI CAYA Engine code, When its cold its ok, as it warms up it misfires until hot or i rev it over 2500 rpm, when driving it it judders, I had the cam sensor changed along with the cambelt & water pump & it seemed better until yesterday when it started again, I have had it serviced recently & no codes in error log book, I have cleaned out the dpf but still happened this morning, She now refuses to drive it & the garage says they dont know why its doing it,

Can any body help or had the same problem,

Cheers

Unfortunately,this 1.6 tdci has not got a very good track record for reliability.Most common issues are egr valves and problematic injectors.Both are expensive fixes.You may need the latest level software loaded into the engine control unit,if this has not already been done.

I have cleaned out the dpf

May I ask you have carried that out.

A DPF is automatically regenerated (cleaned) when it reaches a certain percentage of soot. The driver has no part of that decision and can neither start a regen or stop one (suppose he can by turning off the engine).
