W222 timing chain interval?

[k2025]

Hi everyone!

First post here! Thinking of getting a 2017 S-Class 350d with about 50K on the clock.

When does the timing chain need to be done or does it not need to be done at all?

Also any advice on buying one, please?

Thanks!

Not till it starts rattling, as long as there’s been plenty of oil changes, preferably a lot more often than every 10k (5k would be my limit), you’ll get at least another 100k, before it will need looking at. Oils cheap, metal ain’t.
