So far, so good. Got another hour long run tonight, and that'll be the 300th mile without a light.
First DPF fault code still appears after ever reset, though. |

I spoke too soon.
Within 10 minutes of the run, the DPF warning appeared. Now showing 480A and 481A on the fault codes. I'll reset again, and then I think it's time to try the method I reposted above. Interestingly enough, the backpressure fault hasn't reappeared... just the 2 DPF codes. |

All of it. I used a 100ml shot of JLM DPF Cleaner the day before I cleared the codes, so... 27th Feb.
I'm now down to just under half a tank of fuel with it in. |

Hopefully this'll be the final update from me regarding my DPF :-)
So, in short, I'm now very confident that the issue is now fixed, and the DPF is as 'clean' as it needs to be to perform active regeneration when needed. Firstly, here's what I've learned:
Here's what I did, this morning.
I drove for another 30 miles, and 480A did not appear. Fuel consumption has gone from an average of 35-40mpg (displayed on iDrive) to 54mpg. I think it's over... Last edited by ca2del; 03-03-2012 at 04:29 AM.. |

I just tried this too Dean as i had the 080A code still (assume its the same as had 081A when my dash light came on) i tried the reset code thing about 20 bloody times, car would seem to push on and then mpg dropped to 30 for 2 seconds then back to 50+
Couldnt get it to bugger off, untill i got on the motorway again at 80mpg in 6th. 40miles of this and then a drive home and it has not come back on my code reader (please note my DPF light hasnt come on since i put the dpf cleaner in, i was just curious as to if i still had the remaining code left that you had) Didnt see my mpg drop from 50 at all though apart from gradients so not sure if it was doing a regen or if it even needs to do one My DPF cleaner was 400ml so queit a few ml more then the one you used, so im hoping it has done the trick? So far so good.. |

That's good news.
I was wondering what 480A was all about, and when the light reappeared after 300+ miles, it was obvious it still wasn't doing active regen. 480A is still not present, so I think we're all good for now. For what it's worth, the car felt very different when I drove it this evening. Very eager to rev, and almost fun again :-) |

The first time I got the codes read/ reset at a local garage. It cost £35, and they provided the code and description. After that, I bought a K+DCAN cable and software from eBay ( check my K+DCAN thread for details ), and that allowed me to read / clear whenever I wanted. Dean |

My experience of the dpf 400ml cleaner,
I have recently replaced both stats and occasionally notice the dpf regen on my car despite mainly doing local journeys. As a precautionary measure i added this to my tank yesterday before heading off on a 100 mile journey. Immediately upon hitting the motorway in cruise control, i noticed he mpg needle swing from 50mpg to 20mpg, it stayed like this for a couple of miles before hitting 50mpg again, didnt notice anything else throughout the motorway run. All my journey the car showed min 46mpg and one point hit 50.4mpg (i have never seen these figures) Upon exiting the motorway and driving through the local roads the car felt much more responsive and eager to rev as well as free flowing. Today i drove local and car feels much better than before and deffo more responsive and improved mpg. Looks like the dpf cleaner has done its work even though no light or codes were present. Thanks for reading |

Just out of interest would you guys reccomend to use forte dpf cleaner when you have dpf issues? or could you use it as preventative measure?
The reason why I ask is my car is coming up to 101k miles and frequently do short journeys and thinking of using it as a maintenece I have read on some models there is a indicator within the idrive for the particulate filter, as mine does not have this, when you connect it up to laptop/software/cable. does it show how long you have got to go on the dpf? |

335d DPF light on
On my 335d the DPF light came one a week ago. I have been doing shorter runs of late.
Anyway I read the advice on this and other forums and I took the car for a motorway spin today, about 70mph throughout and kept the engine coolant temp above 75 degrees all the way (drove in 4th mostly) for about 90 mins, I was pushing the car at every opportunity to keep the temp up, it was about 80 degrees on avg. I didn't notice the car performance change at all so I was dubious that a regen had occurred. After stopping and starting on the way home the light came on after a few miles, as it does every time I drive it now. Was this the wrong approach to encourage a regen? Should I be doing steady motorway driving? AND do I need to get the cable and clear the error before I take it for a driver to encourage a regen? thanks. |

Once the 1st stage (480a code) is present, the car *will not attempt to regenerate*. The 2nd stage (481a code + iDrive warning about DPF) requests a trip to the dealer. Once this is in place, it reappears after 10 minutes of the engine being started. Thankfully, I have not experienced the 3rd stage, which I suspect would be a bigger flashier warning, and 'limp mode'. As you have the 480a and 481a codes present (indicated by the DPF warning on dash), then you only have a few choices to make, imo: 1) take it to a garage and leave it with them until it's fixed. 2) go to a garage and ask them to read / clear the codes while you drive at 40mph-ish for 30mins 3) buy a K+DCAN cable and have a friend read / clear the codes while you drive at 40mph-ish for 30 mins I chose 3), because I didn't have any luck with 2), and I couldn't afford 1).

Well I cant afford option 1 either so I will attempt option 3.
SO I get a cable, hook up to a laptop, and drive while someone else watches, and clears the errors you mentioned, any further info on this procedure? thanks, |

As you did the motorway trip and it reached a high enough temp for a regen to take place the thermostats aren't really the problem here.
I do short trips too, usually once every tank or 2 I take it on a longer journey or m-way and within 10 mins it holds onto a gear, rpm stays around 2k in D mode, it's that at 70mph anyway. The temps go from 84 to about 92c and the mpg goes from 50 to 30. It doesn't sound like this happened for you. I would leave it in D when trying to force a regen. In 4th its over revving on the motorway and using incredibly light loading which isn't going to generate enough heat. Only option left is dpf cleaner. Out of interest have these short trips been daily and for how long / how many tanks? |

I replaced my EGR thermostat ( here's my thread ) but only because the OBC hidden menu was showing my temps at 59'C during average runs. Replacing this 'stat gave temps of around 78 - 80'C, which was fine for the regen. I also used a DPF additive, but it didn't work on it's own. I needed to use the cable to clear the error codes during a run. I had to clear them about 6 or 7 times before they stopped reappearing, and an active regen kicked in (you can tell, if you're looking for it). |

HOW DID YOU actually Clear the codes? Did you use a OBD or the sort? |
