Does anyone here (perchance Dr Terry?) know the load (blockage) threshold triggers for DPF warning light and then limp mode? Having an argument with someone I think has bjorked their engine.

Ran a Snap-On tool across the car, no present faults and no historical ones.
Did a DPF regen and it showed 41% soot at the beginning, I shut it down at 0%. The regen cycle on this tool didn’t “feel” good, it was a bit simple/robotic (you set it off, then it just kept going) and surprised me with no idle-down or automated cycle close. With the driver’s reports of the DPF warning light being on “for a couple of months” and a recent limp mode event, I was expecting much more soot blockage. Off for 48H, will see if anyone has thoughts on it by then.

Hi Citroenbender.
Diesel is outside my area of expertise, but try these guys. They know more about DPF stuff than anybody I know of. https://www.dpfcleaning.com.au Regards Dr Terry |

There's always the faithful Italian tuneup, I cleaned out a DPF really nicely on a Mazda CX7 with DPF dramas, thanks to the nearby mountain and my right foot.

The Doctors etc would complain about the car not running right. The service advisor would tell the customer don't worry we will do the Special Tune. I believe the route taken involved a very heavy right foot along the SE Freeway as it was known between Punt and Toorak Rds. |

Cheers all.
I did find some general information that suggested many DPF yellow (amber) lights come on around 50% soot load, but could find no threshold for limp mode - which was reported in one instance recently by the driver. When I heard the car drive off yesterday it definitely sounded less wheezy - surprising as I expected no more than a placebo effect. If the warning light reappears soon I think there are other underlying issues - the car is just a bit shy on maintenance. Diesels aren’t my thing either, the intricacies of troublesome common rail injectors terrify me. |
