Severe Service Schedule - link to premature failures?
Anyone aware of this? Cross posting in the w213, w205, and x253 forums since all models can utilize the M274 2.0L engine. I've been seeing stories of clogged oil separators , turbos going bad, and on the M270 the cam adjusters going bad. I've never been a fan of the 10k mile oil changes and service my cars at 5k. Found this while searching the WIS maintenance section regarding severe usage and the recommendation to change oil more frequently if the criteria are met (50% trips less than ~5 miles where engine doesn't have a chance to warm up). Wondering if those who have had issues fit the bill for severe usage using the 10k mile service intervals.
I have never subscribed to the 10K mile interval that's become the industry standard. I use a 5k or 6 mos. max. More frequent oil and filter changes are cheap insurance, and using a suction pump makes the task so easy. It's a shame that dealers make oil service so expensive for non-DIYers. My dealer washes my MB free; a task that takes more time and skill than changing the oil & filter on late models. A related issue that's rarely mentioned is that oil filters keep getting smaller and oil capacity larger, and we have no way of knowing if the filter is maxed out. There are engine sensors now for everything except oil filter condition; something easy enough to measure electronically.

All those issues you listed are common across all manufacturers that utilize direct injection and turbos. The oil separator is a major issue with M274s because it's located at a difficult place to get to. Also they tend to fail around ~50k miles. Right as the warranty is set to expire.
If you drive short distances during the winter you'll end up with gasoline in your oil degrading the oil. This is a very common issue on Honda's new 1.5L turbo engines with direct injection: https://www.wardsauto.com/engines/ho...lution-problem. Honda was nice enough to extend warranties. 60%+ new Mercedes are leased. MB has no reason to be so nice.
Fully aware - hence the thought that the dilution leads to evaporation which leads to clogged components and bearings going bad.. the domino effect. Wondering if those failures are tied to short distance driving on these engines. Planning to put a catch can on the engine vent line to limit the amount of oil vapor entering the system in the first place.

I'm pretty sure the evaporated fuel is burned in the cylinder and doesn't clog any components. I too thought about putting a catch can on my car. But was afraid it would trigger check engine lights.

Looking at the oil separator system, seems at idle speeds the engine vent valve feeds directly into the intake tube. There is a partial load and wide open extraction as well, but figure if you catch what comes into the intake it reduces what enters the system.
