Just FYI about the MD. Their transmissions are pretty good. Better than the MC for sure.

But it's not all good news. From about 150,000 km on, you could have;

The plastic impeller come loose on the water pump, causing overheating. Fortunately the limp home mode is very effective and the engine is generally unharmed. The water pump ought to last until the timing belt is due, but often doesn't. Replace with an aftermarket pump, they're cheaper and better.

The EGR cooler can split. This isn't too dramatic you'll just start losing coolant at a gradually increasing rate. Again aftermarket is cheaper and better.

The thermostat housing blows apart. That's another tow truck job. Again, the engine should be fine.

The good news is that once you've replaced these bits with aftermarket parts, you should be fine for another 200,000km easy.
