I am on a 2014 BMW 530D now, today I wanna demonstrate how to regenerate DPF with Autel MaxiCOM MK808 diagnostic tool for this vehicle.
Connect MK808 with BMW OBD2 port, press
Service >> DPF SCR aftertreatment >> BMW >> Automatic selection >> Read >> OK >> Yes
Hot functions >> Diesel particulate filter: request regeneration >> Continue
Note: owner-perceived problems such as lack of power or delayed engine response may be caused by a clogged Diesel Particulate Filter(DPF).
It is recommended to perform a regeneration run.
Evaluation of the fault memory completed.
Service function is automatically continued.
An attempt is made to regenerate the particulate filter in the test steps below.
Therefore, regeneration is requested in the Digital Diesel Electronics(DDE) control unit.
The tank must contain a minimum of 10L fuel for the steps below.
The particulate filter can be regenerated only by driving the vehicle.
Time required: about 45 min
Driving profile: drive with moderation.
Press “F1” to request regeneration.
In the next step, regeneration is requested by setting a certain value in the Digital Diesel Electronics(DDE) control unit.
Regeneration was successfully requested in the Digital Diesel Electronics(DDE) control unit.
Turn the ignition off, press “Continue”.
Continue this procedure when the next message appears.
It will now take about 30s until the Service function can be continued.
For your information
If the DPF is heavily blocked with soot, it is possible that the regeneration may be blocked again or not enabled after a brief driving.
In this case, it is necessary to regenerate the DPF by driving on a motorway/trunk road for about 30 min at a speed as constant as possible.
Then repeat the service function DPF regeneration.
The current regeneration status is shown in the step below.
The statuses below can be observed with this display:
– Regeneration enabled or disabled.
– Regeneration active or inactive.
Current regeneration status:
– Regeneration enabled.
– Regeneration was active.
Note: this status is cyclically monitored.
Press “Continue” to exit the display.
Here we go to see the DPF soot mass value in live data, they are continuously reducing during the period of driving.
