RMS failure study - please partake regardless if u had it or not

Hey guys,

So RMS failure is well discussed here, but id love to see if my suspicion is right. I think most can agree that its very likely caused by clogged oil separators. I suspect, that if the car is driven gently, it causes the separators to clog (due to not enough heat/movement in there). I just spoke to 2 ppl on fb amg board, and they both had rms failure and both confirmed that they babied their car.

so, ill create a poll here, please respond if you can - whether u had rms failure or not!!

i would say i drive my car most of the time sort of softly, but at least once a week, ill take it to red line in a few gears, or drive in sport+ for at least 5 minutes. So id say i drive it hard.
soft driving, id say u usually dont take it past 5k rpm or do so once a month or less.

Sure when its blowby gas theres pressure to circulate the vapours but when it turns to carbon build up, because itll eventually do that, I’ gther that the air/oil separators become a bottleneck that traps cylinder pressures.

Making a spreadsheet for this would be good too.

I drive the car hard.

2020 with 12427 miles / 20000 km

Are there revisions of the oil seperators?

I talked to some techs about the issues, climate could be a cause as well.
