High mileage ML350....any concerns?
Discussion
Hi all,
Looking at replacing the wife's Touran with a used 2013 ML350. I've seen one in our price range but it has high mileage, 90k on a 13 plate. so, obviously been a company car and most likely motorway miles all the way and has a full main dealer service history.
I was just wondering if anyone knows how reliable the MB V6 diesel engine in the ML350 is after that sort of mileage? i would have thought that modern diesel engines would go on forever but i just wanted to see if anyone has put a lot of miles on their engine and can comment.
cheers.

We have that engine in a CLS (run from new, now on 113k miles) and an E class estate (bought at 45k miles and now 103k). Both have required inlet port shut down motors (a common fault, which on the E also damaged / coincided with damage to the inlet manifold) but otherwise 100% reliable. Both cars use negligible amounts of oil between services.
It is an engine that likes to be used - my wife's car spends a lot of time around town, and a spirited drive is needed to keep the turbo clear of build up - if I haven't driven it for a couple of weeks, the first hard acceleration produces visible smoke which is not seen again on that journey.

Thanks for the response and advice about a "spirited drive" being required. I look forward to blowing out the cobwebs if required. 😎It is an engine that likes to be used - my wife's car spends a lot of time around town, and a spirited drive is needed to keep the turbo clear of build up - if I haven't driven it for a couple of weeks, the first hard acceleration produces visible smoke which is not seen again on that journey.
Your response is what I thought and it's nice to have it confirmed by a happy owner. 👍
