[Biturbos4] Dashboard center display

The S4 dash is not an easy item to remove - I've done it several times to install gauge rings and the O.ct boost gauge. First, I suggest disconnecting the battery - to prevent shock and potential electrical damage to the cluster. Second, u should disconnect the kick panels beneath the steering wheel and the fuse box (end panel on the driver's side of te dash. You will need to unscrew these panels - several screws are hidden. 
Now, u will have enough room to lower the steering wheel to its lowest point (towards the floor - u will need to flip the steering wheel adjustment lever to do this). You then have to use a TORX screw driver (#20 - if i remember) to remove to screws that secure the instrument cluster to the dash. Then - u will have to shimmy the cluster out of its space - unfortunately the steering wheel is an obstacle - even after being lowered. 
You will now have to remove the three electrical connectors at the back of the cluster. If u have big hands like me - this is NOT an easy thing to do. They are secured to the cluster with plastic clamps that must be flipped upward. Putting these connectors back in (after you finish working on the cluster) is an even bigger PITA! 
Aside form everything I just mentioned, removing the cluster on an S4 is fairly straightforward. After doing it more than once, you should be familiar with the drill. If you successfully re-install the cluster (make sure that ALL three electrical connectors are secure and are clamped into the back of the cluster), when you turn on the ignition - u will have to re-set the date and time. You will also have to use your radio code to re-set the BOSE SYMPHONY unit. This is because you disconnected the power (the battery) and the radio immediately goes into anti-theft mode. 
Good luck.

I guess the "dash" is too broad a term. Specifically, the instrument
cluster is what gets removed. Does that sound easier? (it is!).
Anyway, just wanted to clarify.
