After many years of 156 ownership I've now moved onto a 159 2.4JTDm and so far its doing ok. I read a lot on here about DPF's, regens etc but having never come across these before I'm a little unclear about the regeneration process. I don't have a handbook with the car so when I read 'the car did a regen' how does this happen? I connected the car to FES last night and its showing the DPF is 62% clogged, that sounds a lot to me, is it? Can I force a regen with FES (looks like I can but don't want to without advice) or some other way. The car is sluggish below 2000 rpm just like my old 156 JTDm 16v was when I first got it which I sorted with a EGR blanking plate but I don't want to do this on the 159 as the continual illumination of the engine management light bugged me more and more over time. In the short term I plan on taking the EGR off and cleaning it but at the moment cant afford a remap, EGR & DPF delete so looking at inexpensive options to start with. In summary after all that rambling:
- Is a 62% clogged DPF a problem?
- How do I know when the car is doing a regen? Shall I force one, if so how?
- Is the sluggishness likely to be EGR or a combination of DPF and EGR (New EGR fitted in Oct 2011 with 86k on the clock, now on 111k).
What do you think??
