Hi all,
Our 2006 Multijet now has 168,000 miles on the clock. It has been throwing up an engine management light fault which my Multiscan (Fiat ECuscan) indicates either that there is a differential pressure signal reading high or DPF needs to be cleaned or replaced (fault 1206). The engine performance is hindered when this fault comes on although not consistently so.
I carried out a forced regeneration and this resolved the issue for two to four days. Problem returned worse than ever though today and it took three efforts to get it to go through the forced regeneration as it came up with filter clogged. Finally it did regenerate successfully, but I am assuming I will be in trouble again tomorrow!
What's interesting is that the DPF filter status on Multiscan shows up as 70% clogged which is normal. And the differential pressure reads from 105mbar to 1188mbar in normal driving. When I saw the differential pressure error, I noticed a small bore flexible pipe coming from the DPF was broken and replaced this yesterday. This may have cured the differential pressure fault but the clean or replace DPF fault returned almost immediately.
Do you reckon the DPF needs to be replaced? Would it be worth forcing multiple regenerations in sequence in the hopes of burning off more soot or do DPFS eventually need replacement? Are there aftermarket versions available?
