I recently bought a 2011 320i. After reading up about the 320i there seems to be a lot of negativity about this engine and a lot of people saying it is very unreliable and I should have got a 6 cylinder. The problem being I cannot get insurance on a 6 cylinder due to me being 20 years old. Has anyone got any maintenance tips? Other than the basic servicing, is there anything I should know specific to this engine and how to prevent any issues? Any help would be greatly appreciated.

check the service history
if you find that HPFP pump and 4 injectors were replaced to last version then you fine
if not - get ready to shell 3-4k gbp for their replacement at least
electric water pump (Continental , OEM)is also cost 400 GBP
after that you can navigate the https://bimmerprofs.com/ and put it in bookmarks for all specifics of N43/N53 engines
