Are there any common reliability problems such as the N55 plastic charge pipe that fails? One member sent me the message below. Have others experienced these issues?
"Some people have had B58 coolant loss issues. BMW appears to have changed the B58 turbocharger part number (based on my searching realOEM.com) sometime in 2018 so hopefully that helps with the problem (if the coolant loss is from the turbo, some have hypothesized a faulty radiator cap is to blame)."
I saw a recent announcement that BootMod3 for the B58 is being released. Has anyone beta tested it on their car? I'm wondering what the improvement may be in Stage1 93 Octane? What are the B58 hardware upgrade requirements to use a BM3 Stage2 93 Octane tune?
Any opinions are appreciated. Thanks in advance!

So I'm sure you know this, but in case not, hop over to the F30 B58 section to glean much information in terms of all things B58
