Is it an OM642 engine?

[Robbi57]

Hello fellow enthusiasts

This is my first post, and although I’ve had a CLK for a couple of years, I am considering purchasing an E350 CDI BlueEFF Sport Tip Auto 2010, which has a 3.0-litre V6 engine.

However while there are issues with any engine and history is crucial, I read this article from across the pond that alarmed me titled “Here's Why You Probably Shouldn't Buy A Mercedes-Benz With The OM642 V6 Diesel” on the theautopian.com website, authored by Thomas Hundal, posted October 26, 2023.

I am test driving the above mentioned vehicle tomorrow lunchtime and I wondered whether it has under its bonnet the OM642 engine; and if so should I take Mr Hundal’s advice?

Thank you for reading this and apologies if I am have overlooked the obvious!

Kind regards
Rob

I had an E350 CDI BlueEff 2012 with 67k on when I bought it in 2016 and sold it in Feb 2025 with 208k. No major issues aside from the oil cooler seals @100k. Serviced every 6 months.
All E350's of this era will have the OM642 engines.
