I keep getting this error (30ff)every so often when I'm accelerating. I have checked all my vacuum lines and replaced them. Any ideas what else could be causing this issue.

I think what @9krpmrx8 was trying to say is there are step by step videos walking you through how to troubleshoot code 30ff which includes checking wastegate functionality, solenoid functionality, vacuum line leaks, vacuum canister leaks and intake tract pressurization.

Just google BMW 30ff diagnosis and you'll have hours of videos to watch to help you.
