2016 BMW 750i xDrive G12 Troubleshoot

Not sure what the problem of the car is. Attached are the pictures of the errors that come up:

Looks like one of your oxygen sensors is bad. Put a new one in and clear the codes and see if it goes away.

And you need an oil change.

I think bank 1 is left, but there's about a 50% chance that I'm wrong.

Left, as in driver's side (for USA).

So Bank 1 is driver side (US) ? Just wanted to clarify. Thanks!

Just did the oil change 4-5 days ago and I just wanted your advice if o2 sensor replacement should be done by a mechanic or can it be done yourself easily?

That totally depends on you and what skill set you have and tools you have. I'd consider it a relatively easy DIY job, but others might not.

Ditto, easy DIY unless you don't have jack stands and required tools.

Also, depending on how much salt and miles the sensor has had to put with, it might be a struggle to remove it.

Really, considering how easy it is to do, a shop shouldn't charge you more than an hour's labor to do it, so it comes down to how much you enjoy crawling under your car and doing crap like this.

Last thought - don't these cars have two sensors per side? A pre-cat and a post-cat? Hopefully the code tells you which one to do.

It says probe 2, which I’d expect is post.

Yes, I just found out probe 2 is the post-cat sensor. Thank you so much for your help!
