Turbo LCD Gauge/Instrument Cluster Upgrade Walkthrough for Cayenne/S

This is what you will need as the following: Porsche Panel wedge tool, Screw Driver w/ T-20 bit and Flat head bit, Turbo Instrument Cluster.
Ok with that cleared away, here is the first step. Remove the black plastic gauge cover above the gauges. Use the wedge tool or , in this case I used my fingers! (don't use the fingers, i highly recomend not to , it hurts hahahah). Remember, you will need to apply gentle but enough pressure to detach the tabs off from the top cover of the dash that is over the cluster.
As you can see, the reason why i say "gentle" is because you have the tabs, take them off or apply too much pressure, and those bad boys can break, if anyone had experience with plastic and heat, they can easily become brittle. Just make sure you use precaution.
Next, there are 5 screws to detach the dash cluster cover. 4 screws are attached to the top of the gauge cluster, while one (in back) inside the housing is there to hold the cover in place on the main dash.
Remember, these are t-20 screws. two are parallel on each side , symmetrical to each other The rear screw, is located in the center back of the gauge cluster cover. as illustrated here. Once all screws are removed, just like the black pastic gauge cover, remove the upper gauge cover off gentley. They are tabbed in place, so apply the righ pressure. Note: when you remove the cover, be sure you have the washer for the 5th screw. This holds and aligns the cover of the cluster in place.
