60,000km / 4 year servicing (B2) is coming up soon and I'm shopping around but so far I've been told that an engine fuel filter replacement won't be due until 250,000km by one mechanic and another mechanic told me that the engine fuel filter was internal, so doesn't require to be replaced.... MB official site lists the engine fuel filter replacement every 4 years / 75,000km or as required. So when is it really due? My car doesn't seem to have any issues, so I'm happy to skip this replacement at this time if that's what other owners do.

Is your engine diesel? If gasoline, it's 100,000 miles/160,000 km but it lasts for lifetime. This means replacing when it causes trouble.
