High pressure pump leaks.
Failing thermostat.

Apart from that, they are not too bad
I have always owned Diesel 75s & ZTs (Since around 2003) and in total around 7 of them.
I still enjoy the way the car pulls,especially from low down in the revs (much better than my Mazda Diesel).
But I have to agree, they are very maintenance heavy, In fact, I have had the AA out to every single one of them, at some point, (The only person in my street !). And one of them was, without question, the most unreliable car I have ever owned! and would have gladly paid the showroom to take it when part exchanging it.
They are, However, mostly very easy to diagnose and fix (mostly because of this forum), and very easy to service, with parts cheap and easy to get.
Will struggle to find any kind of replacement.
