What? Jet wash it out? :rofl. My friend, you need to regenerate it by burning the soot particles away from the filter. Either go for a very long drive and get the exhaust hot enough to do this or get the dealer/specialist to take it out and regenerate it manually.

do you know roughly what the trigger is for regeneration, i've had my car for 3 months now and not done any long distance driving. its mainly city driving.
and with a few people complaining about the DPF issues i want to avoid it if possible :thumbsup

Beano 1962:-

If this problem continues & you end up replacing the DPF, I am looking to buy a faulty DPF for a little garage project. (just for you to keep in mind)

Also check my post history I have put plenty of info on regarding this problem. Unfortunately, DPF's are rubbish for the non motorway style driving.

Nish, the DPF light will display when regeneration is needed. I would recommend you do at least 1/2 hr long drives once a month at the minimum :thumbsup
Thanks Neal :thumbsup

might just have to do long reasonless but fun drives :hihi
will give you a shout if your free to tag along

DPF regeneration needs steady cruising at operating temperature about 30 mins over 65mph.

Hardest part about it is finding somewhere you can actually do that :D

The dealer software only prompts a regeneration the next drive cycle, somebody still needs to drive it for 30mins +

i dont think thats strictly true
my 535d was running cool
i replaced the main stat and the temp went up from 78 degreees to 88 degrees
it was no coincidence that it did a regen within 30 miles and steady driving following the replacement
the following week i replaced the EGR stat and it now runs at 91 degrees ,,,up from 88
ive been out today and it regenerated AGAIN within 15 miles max
its now done 2 regens since replacing the stats and approx 400 miles
regards

I have had mine for 6 months now and it hasn't done a regen as far as i'm aware.

does the dash light come on before it does this process?

we run our car up and down the motorways at least once a month if not more, so could it be i'm not getting a build up of soot, hence no regen??

p.s it did smell horrible once - was that it???

As I understand it, the only way to tell it's doing a regen is a drop in performance and increase in fuel consumption as the ECU retards the injection timing to increase exhaust gas temperature. It starts the regen when pressure transducers detect a pressure drop accross the DPF above a set level which indicates it's becomming blocked. If the regen fails to burn off the soot build up and a second level of blockage is reached, the DPF light comes on. Once on, the light can only be reset with specialist kit and the DPF will need to be removed and cleaned/ replaced/ swapped for a DPF replacement pipe.

Not necessarily. If it comes on intermittently, then you have partial soot blockage which can be eliminated by active regeneration. What you are referring to is the DPF on permanently and sometimes EML light on at the same time which will need attention by the dealer.

how would you know the DPF is regenertating?
i did a drive to MK today did atleast 40 mins of 70mph in 4th gear
but nothing came up to tell me its regenerating,
on the way back did the same 40 mins 70mph in 5th gear
still no message, do you think it did regenerate?

Picked up a 2005, 330d E91 on Monday. Salesman, suggested we went for a spin to check things over (as they'd sourced the car from another dealer) and I hadn't seen the actual car. 10 mins into the drive the DPF light comes on! Anyway completed paperwork and ended up driving off in the car, as I was about to do 1,000 in 3 days they hoped the unit would regen. Well this morning I sat for 3 hrs in the dealers as they tried to get the unit to regenerate, including a 60m test drive - but no luck seems the DPF is goosed and needs replacement. Thank goodness for AUC warranty, over £1000 replacement.

Car btw is a Dec 2006 with 56,000 miles on the clock.
