Can anybody tell me if I change fit a 2010 instrument cluster to a 2006 pre fl Octavia and if it's easy to fit also, is there are videos on how to fit it. 

it is possible... but it is complicated and not cheap

 

You would need the new cluster, adaptor loom and 2x new transponders

You would also need to check what ABS pump you have and the CAN gateway would need to be L or above.

 

To do the immo transfer would require special tools
