Long time, no talk... What's new...?

MB diesels has some quality issues from ~2009-2013, especially the OM642. I have one and really like it, but it does have faults.

Early ones (2006/07 through I think 2011-2012) has problems with the oil cooler seals - remedy being a 8-10 hour job of pulling the turbo, intake manifold, and other various goodies in order to reseal the cooler which sits in the middle of the V.

Mid generational ones (like 2009-2012) had issues with their oil coolers, timing chains, and ad-blue system. Oil coolers are the problem mentioned above + these ones have issues with chains stretching. The updated chain supposedly remedies it, but if one has the original chain, be weary and ready to repair it. The ad-blue system on these have issues being a newer system to MB and the common repair is to replace the ad-blue processor.

The newer ones seem to have the bugs worked out, and not too many complaints among friends who work at MB and friends who own them.

Regarding the OM654, I haven't heard much in the way of good or bad... But that might be due to their low rate of adoption here in CA.
