I'm sorry, but I can confirm the opposite. Making the swich off the page settings the items relating to the dpf disappear directly. Then the voice "replacement of engine oil" scomapre also... Trying to start up the adjustment in the way "forced" I said "this function is not supported by the ecu"
ATTENTION! I do NOT SPEAK OF A SIMPLE DPF OFF done by a software such as time or ecusafe, but it is a swich off hand-made.
In any case, the ecu even if it does not take account of the degradation of the oil caused by the regenerations and not ir? active, has 30000km. Then just take the 30000 km since the last oil change is to turn on the light in any case
