How long will a WK2 diesel V6 3.0L motor last?

Very difficult question to answer. So many unknown and uncontrollable factors. Based on recent first hand experience with a failed oil cooler and subsequent failed cooling hose (and a perfect maintenance log book with 95K on the clock) - I would suggest if you intend on keeping for the long term in addition to basic maintenance the main thing to be on top of is any 'undetected' leaks. E.g. slow coolant leak or slow oil cooler leak/failure. Overheating as a result of a coolant leak leading to engine damage / failure has been reported quite a bit of late. Pretty basic but in the interest of prevention I'd be putting a fortnightly reminder in your phone to check oil and coolant level + appearance if not already. Investigate any significant changes in coolant level or appearance asap.

That is all very good advice!!
I would hazard a guess that a fair amount of these engines that have died , have died from over heating .
Some of that could have been prevented if some people lifted the bonnet and had a look at the cars fluids every week or so!!

My 2011 3.0CRD has done 250k and so far engine runs like the day I bought it. Mind you I've ditched the particulate filter and done a EGR disable as these were the only real problems.

Funnily enough took over the servicing job myself today and so far changed the transmission (Penrite ATF FS) and TC fluids and will do the engine (Penrite 5W-40) and front and rear e-LSD diffs (Penrite Pro Gear) tomorrow. Noticed a bit of transmission whine which luckily disappeared after swapping the ATF someone put in the TC instead of the proper Mopar NV245 fluid.

You can use Mobil 424 in the 5 speed Nag1 (Mercedes) box.In fact it was proven to be the Mopar product a few years ago!Myself and others have been using it for years withno problems!
