2012 land rover defender (diesel particulate filter)

Wife had a Grand Vitara with the same problem and sold it because it became such a pain. We had to drive at a steady 58 mph until the light went out. Problem here was that we only have 2 roads which were long enough to do that on, both are an hours drive away, so it was a real pain in the posterior. You must keep the steady speed or it stops regenerating, so if you had to slow down for a roundabout or something, you were wasting your time. Once it went into Shut down Mode, before we went on the run, and I had driven 50 miles before it regenerated, was half way to Dublin. NO more particulate filters here.

:wacky:

You certainly don't need to hold it to 56mph. You could just have noted the revs at 56 and driven it in second, third or fourth gear.

Newer vehicles have second or third generation units that are more easily and reliably regenerated. Most are now fitted with an extra injector in the system to heat the exhaust gas up to the necessary threshold while earlier designs used a program that altered the timing of injection so that the heat was purely generated within the combustion chambers.
They still need a good run now and again mind you and diesel engines are no longer suitable for town driving, for old people to travel a half mile to the shops every other day, or for general flat-cap ditherers.

God help the part time user of farm loader tractors fitted with these things. They are already proving to be a disaster in the industrial plant sector. Several brands of tractors fit switches to disable regeneration in sheds and other places where sparks from the high temperature process could be a fire hazard. If tractors don't come up to the critical temperature needed the driver is 'advised' to manually regenerate, where the unit sits immobile for quite a while at high revs with the extra fuel injected to artificially create the necessary gas heat and burn the soot off, again away from external combustibles.

The "smash the internals out using a loader tractor fork tine approach" worked on my Nissan Navara (as I told the quacker a while ago, so stuff putting copyright on yer dribble:rolleyes: )

There are alternatives to dpf. The new (lightweight:( ) Deutz 5 series uses a catalyst to meet emissions without a dpf making it an ideal loader tractor (but not a patch on the k series)

I suggested the bar as an possible answer several years ago actually. It came from experience with a Mercedes van that gave problems. However, I think software on vehicles might have made these methods rather more problematic on more modern models, just as they have for disabling EGR by the simple expedient of blanking the actuator vacuum or inserting a blanking plate. These methods just don't work any longer on most newer vehicles.
But I see you generally agree with the point I raised about loader tractors, and by implication things that just potter about.

Generally agree, aye, for once.

But don't think you can get complacent :p
