718 Cayman Centre Console Switches

I thought I'd replace the centre console switch panel, as mine had a scratch on it that was beginning to annoy me.

So, I went to the local OPC and bought the entire switch panel assembly, as you can't buy the plastic trim panel on it's own.

The switch assembly comes as a sort of kit that enables you to re-create the particular range of switch options that your car might have. The assembly is a plastic box with a circuit board in it. the circuit board is obviously shared with the Boxter, as it has contacts on it to cater for the roof switches. It's got quite a few components on it including multiple IC's.

Anyway, after a lot of faffing around I dissasembled the center console, made up the new assembly and re-installed it - mine has five buttons - Sport Mode, PASM, Traction Control, Spoiler and Start/Stop. I used the circuit board that came with the kit. After putting it all back together and taking the car for a test drive, some of the buttons didn't operate. Sport mode engaged (but didn't turn off start/stop) PASM didn't work, traction control wouldn't turn off, and the auto start/stop couldn't be switched on or off (and the start/stop inoperative light came on on the dash). After having a think, I took the console to bits and swapped in the circuit board from the original switch panel. Everything now works as it should. And I have a panel which is not cosmetically challenged.

So, the question is, does a replacement circuit board need 'coded', or is it likely that I just bollixed up the re-assembly of the switch box first time round? Putting it together isn't hard, but it is a bit fiddly.

I guess it needs coded.
I scratched the Aircon LCD screen, so bought a replacement air c control panel from a breaker.
When i fitted the replacement aircon control panel, certain functions like PASM, Sports button and PSE wouldn’t work, so I swapped out the lcd screen from the old unit with one from the new one and and replaced the repaired old unit and all worked fine
