Morning all. My 2008 1.6 diesel keeps stalling/choking with no warning lights coming up. I have had numerous DPF issues with this car, so I managed a stationary re-gen (currently living miles from any kind of straight road), which gave me a fault code F424 series which I cleared and then the DPF continued to burn. Ran well for 24 hours but back to the same again with no error codes and it now idles at 1500rpm when it has always idles below 1000.

Any suggestions? 

When did you last change the fuel filter? 

P0428 (catalyst temperature sensor high) has now come up so I think that's the problem identified and I'm going to have to limp 180 miles home today...

2.5 years ago. I have a new one sat on on my workbench at home which I was planning to do tomorrow 😕

I would get the sensor and wiring checked. Would also get the fuel filter done as well to rule it out.

Soooooo, the end of the sensor has fallen off into the DPF giving it a reading of 120% particle content, which unfortunately can't be retrieved without taking the DPF off and cleaning it out or putting a new one on, which is going to cost more than the car is worth, so it's reached 186k miles and I'll be looking for a new car before Christmas (probably a Passat).

Stick another temp sensor on it, should be cheap from a breakers yard.  It's the high temp warning that's stopping the regen, not the fact that there's a lump of sensor in there.

The DPF and cat are separate cores on these, so you couldn't retrieve the sensor tip even if you removed the DPF.  The only way would be to cut it open.  There is the possibility of the sensor tip ceating a hotspot on the DPF core that then causes it to crack, but really you have nothing to lose now so I'd risk it myself...
