diesel particulate filter, error p2463 and 246c

Hello,

I have a 60 plate, 2L diesel Mondeo, and the engine malfunction light has come on.

I bought a cheap blue tooth device from ebay and I am using the free torque app to "talk" to it.

It says the errors are DPF related: P2463 and P246C.

I have cleared the errors using torque and torque says there are no stored errors but the engine light remains on! Something is not quite right there!

From reading the internet the car cannot clean (regenerate) the filter when the light is on. So can I do anything more or is it time to go to a garage? Can it go anywhere or is a diesel specialist best (I went to one when my injector was leaking, would they do DPF work?)

Some web sites claim using fuel additives can prevent or cure this, but other web sites say that they are snake oil and that they get burnt long before they get to the DPF. I have not used any additives. Should I start using injector cleaners and DPF cleaners occasionally or are they a waste of time?

I do not do short journeys, nor stop start journeys through town centres, so I did not expect to be susceptible to these problems. I can't remember the mileage, its over 70k but, I think, below 80k

Thanks, Stephen.

I believe that mileage is when the dpf should be replaced, and if it is like the focus (probably ) there are various other things to do as well.

If you can find a *good* diesel specialist, make him your friend. Send him a card at Xmas. Remember the names of his children.

OTOH, independent garages generally struggle with modern diesel faults, and dealers are no better, just more expensive.

Snake oil.

A friend with same car had same problem. In his case it was the flexible hoses that go from the DPF to the sensor. The hoses had perished so giving wrong reading at the sensor. New hoses solved his problem so may be worth checking on yours.

Very *very* true! Increasingly, not just true of diesels.

I consult mine in the boozer, and make sure I always buy the beer!

Definitely check the various pressure sensors and thermocouple wiring for anything obvious, but that code is definite "DPF full of ash" code. So it'll be new filter or DPF-off and remap time.

Well the engine has since died (see other thread) but as an update which may help someone else in the future:

Whereas my elm device and the torque app found two fault codes, the garage found (I think) four of them. One was from the pressure sensor, but they checked that and it was fine. They used the computer to force the car to regenerate. I took it for a long motorway drive (2 hours, I think 100 miles) and it has been ok (dpf-wise) since. So it's all a bit of a mystery what caused it. I think the problem was compounded that once the engine light was on, the car would not regenerate, which just added to any soot.
