thanks Mark for this but I'm guessing my Vaporizer is working ok because whilst the van is running a forced Regen there is some major heat coming from under the van and some odd smells coming from the tailpipe indicating soot being burned off, just not enough , the van is a 2014 and I've used it for courier work for the last 12 months with a lot of short journeys, I've bought a can of cleaner that you spray into where the temp sensor goes and will give that a go later fingers crossedmetalworker0 wrote:I've also read up a bit more on these ...there is a vaporiser - basically an electrically switched nozzle that squirts diesel into the dpf during regeneration ..this nozzle can get carbonised up inside (heat and diesel = carbon) ..with no way of unblocking it. the software cant even tell when this has happened ..just tells you dpf is blocked ..not the cause ...so your regeneration may be happening ...but with this part blocked, no fuel is getting to it, to actually carry out the task.
So worth checking first - how you actually check i don't know ..as i read that often you cant remove this device as it is tight, too tight for an open ended spanner- because of age and rust and you may have to cut the pipe leading into it in order to put a socket on it to remove it ...so to check it, often means to destroy and replace it. unless you can find ring spanner with a slot in it
so there you go, me trying to learn about this new technology - and hopefully explain how it works ..even though i don't have it on my own vehicle.
hope I'm helping people though !
A new nozzle/ vaporiser may not cure the problem as it could of been happening for a long time ..until the DPF became completely clogged and now maybe the only cure is to take the DPF off ..and doing what it says in the video above I linked to
all the best.mark
