W212 250CDI maintenance

[Output Flange]

Evening chaps.

My ‘13 plate E250CDI is just about to tick over 70k miles.

It has been maintained by Mercedes dealers so far, according to the service indicator.

Outside of the set schedule, what should I be looking at for routine maintenance at this age/mileage?

I don’t mean consumables like bushes, just anything model-specific that I should bear in mind.

Thanks

At that age/mileage I'd do the gbox fluid & filter.

On my Merc's I do it at 5yrs or 50,000 miles.
