@Stuart21UK glad you are managing to dry it out.
I remember now that Porsche (well Nottingham OPC) completely removed the ‘filters’ that come as part of the drain tubes when they re fitted mine – maybe something to bare in mind?
Few notes from my Jan 2017 post – invade any of it helps at all – what boxes ‘front systems? & part assist’ were damaged etc:
“Car collected from Nottingham OPC today – it has had pretty major work to (hopefully) cure the condensation issue.
I’ll list what I have been told by the (very thorough in explanation) tech (Jack).
Issue being condensation – cause – blocked rear drain tube (passenger side).
Apparently the rear drain tubes on the 981 (there is a drain pan under the ‘flaps’ either side of the roll bar – these connect to a drain tube) have filters on them near the bottom.
My drain tube filter had blocked on the passenger side – I’m told debris was several small leaves – water had backed up over time (some ran out / but the filters were sufficiently blocked to allow water to gradually back up and seep into the interior.
In my case into / under the passenger seat and carpet – I quote “Nemo would have been quite happy there…”.
Resulted in removal of the lower wing / sill side panels on both sides / then behind the intakes access to the tubes / also removal of the carpets / seat etc etc to dry.
Both control boxes (park assist and the “front systems” electronics were wet – and the connectors to them very corroded.
The wiring has been cut and new connectors added (porsche technical fix as the loom is huge to replace and would involve removal of so many parts).
So – New connectors / fixings / control boxes.
Apparently it all seemed to “work” (when wet) – I’d never experienced anything odd (apart from the condensation) but when dried it started to throw errors up – multiple dash lights etc and also resulted in the rear brake lightbeing replaced….(?).
Drain tubes were cleaned and filters removed completely.”
Hoping yours was caught quicker than mine 👌🏽
