Well I was all excited to get a z4 now I'm a little concerned! Vanos system issues I've been reading about, should I worry? 70k miles on a regularly serviced 2004 3.0i...just don't wanna jump into something that needs an expensive repair..thanks!
If you're handy with the spanners a replacement seal kit to bring back the efficiency & stop the rattles is less than £50, it doesn't seem like a terrible job to do.
