BMW M2 Forum - View Single Post - Exhaust valve test

Guys and Gals

Just got a 2016 pre-owned M2 with Milltek exhaust.

The exhaust valves are permanently open. I need to test the system to diagnose the issue. There are many possible reasons - I need some advice on how to track the issue.

Can anyone help please?

Thanks
