My own car has 320,000km, I bought it new in 2009. Have taken it off road. I've towed with it. I've driven in 50C heat and -11C cold on snow and ice. I've taken it up the Alpine Way (with a caravan) and up the Stuart Highway.
I've had some turbo issues. One turbocharger failed through age. Replaced it with a cheap one off eBay, won't do that again, that one failed. The current turbo is a genuine Honeywell Garrett.
I had some DPF issues - wrote to auggie on this forum, he fixed me up with some sensors, no more drama.
Other than that it's wear and tear items. Wheel bearings, brake pads that sort of thing.
At 323,792km my engine purrs. Never had an injector out. Have used Liqui Moly injector cleaner a few times. Replaced the SCV once (it's a small part on the fuel pump). Don't have a boost controller any more, I use a Tilix valve.
My intention is to see that many km again - and judging by the sound of the engine, I probably will.
