Interesting OM642 dissection
my main takeaways:
1. Change your oil
2. 642 seems to be a very stoutly built engine
3. The egr system causes intake flaps to fail
yours may vary but it’s worth a watch.

I knew about a owner that brought his GL450 for warranty because the car was overheating and the dealer found that he never changed the oil for more than 65K. According to the owner, nobody told him that the car needed oil change!
