Most of the problems seem to stem from the adblue system on the newer diesels. Troublesome and stupidly expensive to fix (for what it is).
 
Between around 2015 and 2018, the W/S205s were marked 'd' on the bootlid and had the 671 diesel unit. After early 2018, it changed to the 674 which as others have said can be a load of trouble after about 75k miles.
