Well I bought a car fitted with an N47 engine, the car had been misdiagnosed as requiring a new turbo when in fact the MAP sensor was blocked with crud
Anyway the service intervals are 16000 miles or two years, the car has had an annual oil change at least in the past owners care.
I'm going to replace the timing chains in the near future as on cold start there is a 1/2 second rattle before the tensioner takes up, but in terms of driveability the car is streets ahead of it's predecessor.
The car has an "they all do that" attached to it in the same way as the k series with HGF, but just like the K series there is a reason, usually owner neglect for failure.
Talking of timing chains, the guides and tensioner have been modified, so in conjunction with real oil change intervals, I expect this to be the fit and forget for the next 120,000 miles.
All cars have maintenance requirements, and that is the reality of life.
