Code 30ff keep coming back

[WarMad]

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.

Many things.

I would start with a smoke test for leaks. Costs like $10 bucks to make one if you are on stock inlets.

If you are on stock turbos, 30FF means you should start looking for leaks as @Torgus suggested.

Start there and go down the list of possible solutions

What tune are you running? JB4 only? JB4 stacked with MHD? or MHD? COBB?

Post log if you have them.

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.
