If you drive only short distances or your journeys contain frequent stopping and starting, you must initiate the regeneration process every 500-800 kilometres (300-500 miles). To do this, drive your vehicle at 80 km/h (50 mph) for 40 kilometres (25 miles) in the lowest possible gear whenever it is safe to do so.
This combined with short journeys and occasional low fuel levels would be enough to cause the problems, but the differential pressure sensor was also flatlined. The DPF stats showed: – 875km average distance between regeneration – 683km since last successful regeneration – 128km since last attempt (unsuccessful)
It's not about regen itself. As those are fine. But I'm thinking the exhaust/engine is not getting up to enough temp on my usual runs. As it's steady 80-100km/h driving for 30 min, and a pause in between, so 15 mins of engine on.
Hi, having had the same warning come on my car 2011 2.0tdci I started investigating: Happened twice on longer runs, car probably trying to regen, it looks like it might be the fuel vapouriser in the dpf, these get blocked so the dpf can't regen as its basically a glow plug that helps to burns extra fuel put into the dpf when it needs a regen.
Here’s our top five tips on keeping your DPF clean and trouble free. 1. Drive Faster. Contrary to popular belief, driving faster could actually save you money in the long run. DPF regenerations can only occur when certain conditions are met such as speed, RPM and engine temperature. Unless all the conditions are met, the DPF regeneration
My old MK4/5 ran at those figures consistently through the whole 270k that I owned it and was fine, the previous MK4 was the old post injection type DPF and ran that up to 300k and never had a forced regen in its life but constantly showed 2-5% after a regen, you won't find the distance/aborted regen for these cars as it wasn't written in to
Look at DPF differential pressures & reading 0.49kpa with engine not running. New DPF pressure sensor supplied & fitted, you guessed, no good. Pipes off pressure sensor & blown through & all clear, no good.. Starting to get a bit tedious now! Even tried regen via Snapon scantool incase the car doesnt speak Chinnese but same results.
The garage fitted the new vapouriser (I imagine by taking off the exhaust) which was 2 hours labour, and then did a static regen (0.75 hrs labour). I was concerned the car would refuse to do a static regen with soo much soot, but it was fine. On picking up the car the DPF pressure at idle was 0.0kpa and at 2,000 rpm it was 1kpa. 28% loaded.
got 269f recently, deleted popped up again, car run fine but it tried to regenerate every 10 miles (pretty annoying) forced regen wasnt able to run, so I started digging where the hell this fuse is on my mk4 120 kw (2012) - it was the F6 in the engine fuse box (20A), obviously blown, changed it, deleted dtcs and it runs sweet like a charm now. hope it helps
So the take away from my experience is that if your car is constantly trying to regen, and you have the P246B code in the PCM, and a high pressure reading in the DPF with the engine off, then it's most likely the Pressure Differential sensor. Thanks to all those here that offered help and advice.
The PCM will choose the optimum time for the regeneration of the DPF. Under normal operating conditions the regeneration process occurs when the PCM has calculated that the DPF requires regeneration and that predetermined vehicle conditions are met (for example coolant temperature, vehicle speed and engine load).

Yeah, I'm seeing 630 degrees C during a regen, what does your soot load and DPF load go down to after regen? 2014 Mondeo MK4.5 Business Estate 2.0TDCi 150PS (DW10c) with Android 'Tesla' style headunit
