AnooooOH installed the M3 cluster on his 135i so apparently it is possible to code big-screen-type clusters (the M3 cluster like the E89 cluster have big screen and they are more complex than 1-Series clusters). So.. Will it work? Yes, after coding.
The second question is.. Will it fit? I don't know. Probably it will be necessary to adapt the dash hole or the cluster mountings.
