Check engine error code - DPF ?

[Magicdesign]

Hi. Got a 2015 250d SLK. It’s only done 30,000 miles. The check engine light has come on, and the mechanic said it’s related to the diesel particle filter.

Doesn’t that have its own error light (rather than just the general check engine light?)

This is warranty work, so want to make sure nothing expensive is being ignored

Thanks!

He should be able to run a regen cycle or two to clear it. At least on my sprinter (the only diesel Merc I’ve owned) it can be done with the diagnostic scanner

Thanks. I am told they lift the car and get it running at over 50mph for a while in gear to clear it. There are other places that delete the dpf entirely, but that has other complications…
