Ok, so:

The left bank on a LHD car is for the Status Check / Logs, Ultrasonic Alarm Sensor Disabling, and for Parking Space Gap Measurement.
The right hand bank on a LHD vehicle was later used for STOP START vehicles. Only the middle button was used for the ECO function, to temporarily disable the Stop Start system. The switch blocks are all different (even for the blanked ones) depending on if the Services Module, Additional Programmable Heating or Stop Start options were fitted.

So although it is blanked, I can't tell which version you have even though it is not functional.

Thanks for the quick reply.
Mine has the Webasto heater and the NG4 SOS thingy, if thats what you meant. I also saw these buttons on a real C5 where it switched/dimmed the interior lights.

theres also this picture, with the ECO OFF and ESP button

Theres no real way to figure out mine, right? Well apart of taking the whole dash out and backtracing the wiring...
Would it be stupid to wire up to a button and see if it works?

Ok, the reason why these changed, as the last production run had the Touchscreen Option. Because of this, they removed some of the controls from the centre console and moved them to the button bank either side of the steering wheel as you can see from below:
X7 Controls.PNG
For C5 X7s without touch screen systems, the top row of buttons were used (1-4)
For C5 X7s with touch screen systems, the bottom row of buttons were used (1-6)

So you can see (4) is the AFIL (Lane Wandering), (5) is for Stop Start vehicles and (6) is for ASR / DSC

Be aware that these will have different electrical harnesses, so don't experiment if you want my advice or you could cause problems.

Thank you for the detailed answer. i will not experiment.
I just bought a 508sw buttons / connectors for that bank and im doing the BSI trunk opening project. I will leave the built in, not used plugs aside.

i used the pug 508 buttons, took 30 minutes to wire it all up.
Used a Guide from our Russian friends.

I mean, they are doing gods work finding these stuff and documenting it so nicely. They made some crazy guides.

Also i found like 20-25 cables cut just before the BSI. I keep wondering what those are :) One day..
The right bank had pre wiring with a connection block, (where i put the 508 switch), stragely they are all connected to the BSI. :|
