firstly let me take this time as a newbie to Pistonheads to say a big hello to all you guys/gals out there and why didnt i discover this site years ago?

anyway yet another DPF post on the Beemer section
my 07 plate e92 3.30d threw up the light 2 weeks ago,its been on the drive unit last Thursday when my local mechanic who ive known and trust for the last 25 years said "leave it with me"
i have already tried a force regen and jpl fliud too with both not working, my mechanic called me and said he had put the car into regen mode and take it for a blast on the m56, he said it literally kept getting to 98% then saying abort regen

it threw up a code and he googled this to which he said basically its blocked up big time

hes sent off for another chemical that hes used before and will get back to me

i guess im asking is there a point when a DPF is beyond repair/regen?

i could be asking a silly question as with all cars its different for everybody

ive spoke to a guy on the net who said and aftermarket DPF is not worth touching and a OEM Beemer one is £1200 supplied and fitted

now im a plumber so not skint but a £1200 garage bill isn't what i need right now

can anybody assist or give their opinion please

cheers

Hello Ashton welcome......I cant help with a cheap option but I would add once you get it fixed id sell it ,because I reckon the next thing to go will be the turbo and its downhill all the way..........and re 2007. that year the N47 engine was introduced( but I think 57 plate onwards unless some were put in earlier)
if thats yours then the Timing Chain could be next

Good luck buddy

crikey its all domm and gloom with beemers
i just sold an E90 with a knackered head gasket for next to nothing
i only paid £6200 so i think as far as the miles go i could probably get close to my money back

ill see what mechanic says re:DPF and possibly look at getting rid and doing what every single person i know has said "

"buy a honda"

ive had 31 beemers since 1987 when i passed test, and to be honest only 1 didn't let me down, a 3 year old E46 that i bought off a doctor and did 80 thousand miles in and only paid 10k for it and it had nothing but services and tyres in 9 years

still open for comments if anybody wants to help further

I have more helpful advice. You can have your existing Dpf cleaned by Dpf clean team (removed and sent away). This is if a forced regen doesn't work- Caution: do not allow anyone to try a forced regen in the workshop.
When the Dpf is clear the cause of the blockage needs fixing-normally due to glow plugs not working or thermostats faulty.

This, had one done last month on a mates X5.

Town driving will always kill them. Mine has 148k on it, but i spend my life at 80mph on the motorway. ( It will probably fekk up now)

Re the last post I allways thought all my motorway stuff would keep it all clean (about 15k a year motorway) ,thing is I realised that since new in 2 and a half years my 330d has never really gone over 2000 revs 2000 revs is 90mph. Did some research and come up with Italian Tuneups now when im on a motorway for about 3 miles I will go up and down the paddles going from 3k to 4500 RPM and back to 3 and up giving it a real clear out and I have to say since doing that for the last month the engine seems so much freer not sure if its a placebo but it seems as though its been released somehow

maybe im sounding a bit crazy but the more advice i get the more i get a little itchy
people are saying fix it then sell it?

i always stayed away from really high millage beemers after i had an e39 with 147k that i was literally throwing cash at##mines only done 71k
which in my opinion for a 6 pot engine isnt that high
im fully prepared to spend money on any car i have just not huge garage bills 6 times a year

will the turbo now blow?

timing chain?

where should i go from here once repaired

i found a guy on Facebook in Macclesfield who is a DPF specialist and he said a good aftermarket new dpf supplied and fitted is about £700 and an OEM one supplied and fitted would bve about £1200

Some people to the taxi driver route and have the insides of the dpf gutted and welded back in.

Combined with a quality remap gives some people a trouble free solution.

The current MOT test has a visual inspection to see if the dpf is still present, it doesn't test of it is functional or just a shell.

As for the whole buy a honda thing, they have dpf issues too. Every diesel does.

So far with mine, my solution is a blast every ten days of about 30 miles at 70mph, 4th gear, 3000 revs. So far so good.

Last 3 BMW's

335d 160k original DPF, new owner town driving, light came on within a month

330d 187k original DPF , new owner now on 210k same DPF

Current 2012 X5 148k on original. Long runs i put it in sport which seems to do the regen easier.

I do have the Carly thingummywhatsit to check it too.

How blocked is the mechanic saying it is ?
I had faulty pressure sensors on an 07 335d which kept resulting in a dpf warning.
Might be worth getting these checked first.

One thing to note is that DPF filters are consumables. If you do town driving your filter will fill up with sut more frequently and therefore require more regenerations to burn off this sut. Eventually it will wear out and need replacing.

I agree. A good remap will also be smoke free on stock hardware.

my mechanic got a chemical (not too sure what its called) he poured it directly into the dpf and took it about 40 miles,he said there was a ton of black soot coming out of the back and a big gulp when he thought the car was dying

eventually it started a force regen and eventually it cleared

he had to reset a load of codes afterward but got it sorted in the end

its quicker now than when i bought it a few months ago (goes like stink)

all in all it cost me about 3 hours of his time plus the chamical and cost me £90

fingers crossed now

i may still sell it,not too sure if i can doing with agro every few months that bmws tend to always deliver

Well done ...my thoughts re selling were based on what may this bunged up DPF have set up re problems in the future
