This will have the 2.0 N47 engine which is more prone to timing chain failure. They always benefit from more regular oil changes than BMW stipulate. If you're happy it has been serviced annually/10k miles, then it's likely to be long lived

The area to keep an eye on is sooting up of the EGR and inlet manifold. These clog up and reduce airflow resulting in higher risk of turbo damage. This issue is somewhat unavoidable unfortunately. You can get these cleaned but it is a manual process. Separately you can consider getting it carbon cleaned too. DPFs can also get problematic at higher mileages (c.120k) and these an now be cleaned (off the car, not using injected chemicals) rather than the incredible expense of getting them replaced which is what BMW will tell you

As it's auto, then it will benefit from a gearbox service. BMW claim these are sealed for life but the reality is that will benefit from a service every 60k miles. It will cost around £600 but will futureproof your gearbox. Also worth getting the rear diff oil changed too. Less than £100 but vital

Apologies that this may seem somewhat depressing but I know from first hand what these cars need having owned a few
