2013 BMW x1 2.8Xdrive
My car I believe has the N20 4 cyl. engine. On start up it sounds like a diesel engine and get a little quieter as it warms up but still has a diesel like sound at idle. I use Castrol synthetic oil, if I use say Mobil 1 will it be less noisy? What are the causes of the timing chain issue with this engine can it be prevented?
Thanks,

I don't wanna say oil brand will fix it as it might. But oil weight may quiet it down

Are you sure you’re using LL grade oil? What is your oil change interval? Does this happen more as the miles on the oil change go up (meaning is it quieter after a fresh oil change)?

The N20 like all DI engines have noisy valve lifters during cold start-up. Something to do with emissions. It does quiet down after it is warmed up. I think the X1 without a hood dampener amplifies the sound more so.
There are numerous threads on the n20 noise in various BMW forums. Oil type is seldom the fix. It's just the nature of this DI engine and it is not a nice noise either. |

The video attached below is my 2013 N20 on cold start up. 81k miles. I have been told it sounds just fine by a resident expert BMW mechanic. Oil used for last 50k is LiquiMoly, but I am switching to Penz Plat with next change based on input and ever changing BMW specs. The PP is LL.
