ln local driving my D250 initiates a regeneration approximately every 100 miles. When it happens l try not to turn off the engine until it's finished, but it's not always possible.
ln that case the vehicle will try to do another regeneration, often the next time the engine is started. |

Oh, it’s even less than mine. I tho in mines does it approximately every 250/400km, depending on diving types. Yes when I notice high idle rpm or higher than zero consumption when the gas pedal is not pressed I know it’s regenerating so I try to let it finish.

Yours sounds fine, it depends on the type of driving that you do.
When on longer journeys mine will regenerate every 3-500 miles although it's not always possible to detect when it's happening. |

Is there any lights that come on the dash when a regeneration is happening?

There's no lights on the dashboard to tell you.
The only real clues are, the idle speed is a bit higher, start/stop won't work, and the fuel consumption drops very quickly. However if you've not recently reset the average fuel consumption you won't notice the change. lf you stop the engine before the regeneration has finished, it will try again. Eventually you'll get a warning light if enough of them fail. But it's never happened with mine. |

In city driving, my D200 (3liter) regenerates every 250 km. What I find strange ist that it regenerates a lot more often when driving on highway (every 170 on average).
I looked at the live values with the GAP Tool, and the DPF inlet temperature sensor reads about 350°C when driving 130-140km/h on the highway. That is too low for passive regeneration (450°C). |
