DPF Cleaning fluid

[paneuro]

Hi, I have a warning on my dash that the DPF unit needs attention. I assume this means it requires regeneration. Any pointers on best type of additive fluid to use for this and what is the most successful procedure,  Thanks Paneuro.

Someone with the software can trigger a Regen if your isn't doing it it's self. For the regen cycle to trigger you need at least a half hour forty minutes with revs at 2500 or above you also need all the Glo plugs working as BMW use them to boost cylinder temps. 

Now the actual DPF, depending on DPF age and the type of journeys undertaken we are back to Software to measure the ASH content % as this is the bit that tells the car to show the warning and eventually go into limp mode.

Solutions (1) take it for a good trash (Italian Tune Up) see if that works (2) Software there are several Diagnostic systems now capable but as I have INPA/ISTA that is my weapon of choice (3) Last is the Garage many will recommend NEW DPF ££ some will recommend DPF cleaning ££ (friend of our sons had this done seems to work)

Both the last options will need software capable of resetting all the DPF adaptions to factory settings

motorway for 30 mins, 3rd gear... get the revs up and sit there with the revs up higher 3k or so. This will regen and blow out all crud.

When driving as normal, get the revs up, use up the gears before changing, dont change gears too early. Not only good for the DPF but good for your flywheel if its a manual.

Diesels need to be driven hard sometimes.
