Does anybody know the interval for Changing a fuel filter on a diesel V167 ? as recommended by Mercedes.

I'm not sure of Mercedes' official schedule, but given how dirty diesel can be it is generally in the industry every 10-15,000 miles (16-24,000 km).

Jealous here that you still have diesels!
My 164 and 166 Diesels required a fuel filter change every other service, which would be 20,000 miles.
The bigger concern was water in the fuel, which, in those models, was separated within the filter. There was no water drain, so changing the filter also removed any collected water.
