I found some discussions on the reliability of the N63TU2 engine but most are from 2017 and a lot of time has passed so I thought I'd ask now in 2020.
I'm looking for a well equipped 540i XDrive on the German market (no luck so far) but I've found a really nice M550i XDrive at our local Czech BMW dealer for basically the same price and I'm wondering if that would be a very risky purchase.

It has 70k km which is about 44k miles and there are still 2.5 years of extended warranty left. My questions are:
1. What should a potential buyer check in advance - have there been any global recalls that the car might have missed?
2. Are there any mods or special care that would help the engine last longer? (Besides more frequent oil changes, of course). I'd rather invest $1k in advance than have to replace the engine for $5k+.
3. Are there any stats regarding the average failure of these engines? I plan to keep it for another 20-30k miles. What are the changes of the engine surviving a total of 75k miles? :-D
(Also I'm driving mostly short distances (30 minutes to the city center) and I'm afraid that's not very good for the engine...).
