Ive bitten the bullet and booked myself into a garage (Colin Woods, BMW Specialist) to see what they think the issue is and quoted me as being able to sort the regen and take away the light taking no longer then 2 hours max and costing circa £100 I can live with that! Especially when my local dealer charges £120 an hour... Plus vat!! Fingers crossed! |

Well its been a couple of days now so i thought id post where i am currently!
I spoke to a few garages about different techniques of clearing a DPF. One bmw specialist told me they didnt want to force a regen as itll run whilst the car was stationary as i posted in a video in here. They said they either replace the filter or put some cleaner in the tank and charge me 2hours labour for the honour. A well trusted friend who has a garage also told me the same! So i bit the bullet and purchased the forte dpt cleaner, with baited breath i poured it in! I then headed to my nearest motorway 30miles away. The light came on as i expected, but before joinig the motorway i pulles into the services and cleared the codes (i did this with the engine running for the first time... Wether this helped i dont know?)i then did around 40miles at a constant 80leptons and guess what.... The light has not returned! Only a smell of eggy crap and the dpf cleaner! So hoping thia has cleared it out! Ive since done an extra 70miles with no light so 110 all in! So ive paid ten pounds for bmw specialist to read and clear several codes and 15 pounds for the dpf xleaner and fingers crossed all is well! Also just to add im seeing 83/84 on my temp now in 6th as opposed to the 78 i reached in 4th |

i don't the hard facts but when dpf warning light comes on the ecu stops all normal regens
theres something about a hard motorway run 80+, which causes enough heat in the dpf to cause a burn off & clear the dpf. as i've said this is imo but its what i've used to clear my dpf warning light |

Finger crossed mate.
The eggy smell is coming from the catalytic converter likely due to the DPF treatment and it isn't burning it off completely. Sounds all good so far but occasionally keep giving your engine a boot through the gears to clear it all out and that smell should disappear and then hopefully everything will be OK. |

Bought some JLM DPF Cleaner today, in the hope it might magically fix everything
So far I've done 70mi @ 80mph with that in the tank (I think it went in the tank, but the nozzle didn't quite fit ) The light appeared after the first 10mi, but that was expected. I'm hoping it's begun cleaning the DPF in some way, even if it wouldn't do a full/normal regen. I'll be able to clear the codes and check temps and pressures later this week, but I'll need to keep using the car as my daily drive until then. Anyone know what backpressure I should be seeing in DIS as standard? I'm thinking it may actually be a broken sensor rather than simply a clogged filter alone. Dean |

just bought some granville DPF cleaner also at 15quid
just as a maintenance/percautionary measure,so il give it a go and keep all up to date, car running perfect and havnt seen dpf light yet and im hopeing to keep it that way, with this additive and odd blast when car warms up,as i only do 6-7mile runs usually and odd 30-40 mile run, bmw09 320d e90 lci how often would this car regenerate?

99% of dpf cleaners all manufactures etc
say 'PREVENTS DPF BLOCKING' so i would of thought it would be good maintenace wise as car has 101,000 miles does these cars have DPF fluid does this have to be changed?

If you have that many miles on an lci, I assume it's done lots of long quite long journeys? Your DPF should be quite clean then
They are Sealed units I think. Guess the question about DPF cleaner, is what else is is doing to your entire system? As a one-off clean it is I am sure fine..but more often?

So, cable arrived. Only took a day! It took almost as long for me to work out how to use the f'ing software on Windows 7.
Anyway, Codes read @ 9pm: A6D1 / 21 480A / 71 481A / 71 41F2 / 04 D813 / 21 Drove 40mi, 80mph - light on dash did not appear. Codes read @ 9:50pm: 480A / 41 So, now I do a bit of googling work out what they meant / mean. Dean |

Great, so.. removing the completely irrelevant error about the Cabin electric fan, and Cabin auxiliary coolant pump
A6D1 / 21 41F2 / 04 I'm left with: 480A / 71 - DPF 481A / 71 - DPF D813 / 21 - Any ideas what D813 means? And what does the number after the code mean? It was labelled "Kind of error", although it's referred to Logistic Counter elsewhere... Dean |

Just picked this up at the 5er forum...

I expect running at low RPM may hinder the cars ability to sense the high backpressure, meaning it will initiate a self-regen. Might be an option for those who don't want to buy an additive? |
