i got a crack on the plastic cover of the cluster, and i buy that part but dont know how to remove it, any tips for that

 

Gotta lower the steering column. Couple bolts underneath. Then there are a couple screws on the underneath of the top portion of the gauge cluster. Might be some more but besides the steering column it is pretty easy once you just start looking for screws holding it in.
Should be able to find a diy on it. I know I found one a while ago when I had to remove mine.

 

Qube's website http://www.qube-engineering.com/Documentation.html shows you how to remove & install his cluster.

 

done... it was very easy, finaly got it like new again, thaks guys...
