Hi,
I have been having some problems with my C4 VTS HDI, i have been trying everything to sort it out. it began with a gradual loss of power, running rough, surging and running bumpy on pull off, no errors reported in lexia. Checked all vacuum circuit and everything is ok, replaced turbo copy sensor (just incase) to no avail. I then thought EGR? So i brought a blanking plate from ebay fitted it and hey presto she was back to life. But i was then told by a few mechanics that this is required to regenerate the dpf. Is this true? So i kept an eye on the soot load on the dpf via lexia, and it has gradually increased over 400 miles from 28% to 85%. The ecu should signal a regeneration at 80% according to the lexia. So i have now removed the blanking plate, to which the car is a dog again. i had no error messages or anything to suggest a problem but lexia reported soot load of 85%, didnt want to risk it.
Can anyone clarify if the egr is required for regeneration of the dpf in my car? it has the siemens sid803 ecu, 2.0hdi 136hp 16valve engine. DW10BTED4.
Many thanks
Richard
