    Does my 2007 2.0 Z4 suffer from DISA issues?

    Just bought my first Z4, it's a (UK) 57 plate with a 2.0 engine. Only has 38k on the clock. I've been doing my research about what I should be looking out for and read some horror stories about the DISA valve destroying engines!

    From what I've read, the 2.0 doesn't suffer from the same DISA issues as the larger engines do. Can anyone give me an definitive answer?

    They had issues with the m54 6 clyinder engine disa valve but I don't know about other engines. The pin would come out that supported the flap. I've only seen one engine destroyed. That's the first thing I looked at when I got my car replaced the flap and pin with this after market kit worked great.

    All 6 cylinder engines have DISA but the Z4 2.0 is a 4 cylinder N46 and does not have a DISA
