Driver side - Water ingress bonnet release lever?
Discussion
RHD 2004 Cayenne S 4,8L
I know that Porsche Cayenne's suffer from wet carpets caused by a blocked drain plug in the bulkhead.
I have removed the rubber bung from both sides and the reservoirs are dry.
However the driver's carpet still gets wet and the water seems to be coming from the bonnet release lever.
Any ideas how the water could be tracking the cable?
I have checked the door seals for damage and there isn't any.
When I move the bonnet release leve water runs down the plastic trim onto the carpet.

Thanks Chris for your suggestion and I will investigate that potential fault too.
I should have mentioned it is rain water entering the cabin. It is pouring with rain right now and I can see the water running in from the release lever.
The lower trim will be removed first to see wher the water is coming from.

No new screen and I've owned the vehicle for over a year and this is a relatively new issue. Last summer allot of trim panels in the bulkhead were removed to find an obsolete tracker device that was sucking all the power from the battery. Perhaps something was was disturbed then.
I am trying to find out if the sunroof or T-Track roof channel have drain tubes in the A-pillar.

Update:
I have removed the A-pillar trim and the water is leaking in above that under the headliner. It then runs inside the A-pillar etc.
Unfortunately it looks like a big job to remove the whole headliner to dicover the leak source.
Does anyone know if there are sunroof drain tubes at eack corner of the sunroof?

I can't speak for the Cayenne but it's pretty standard for drains at each corner. It's possible the drains have become clogged and then the water pools and finds another way out. If you open the roof you should be able to find the drains at the front corners of the mechanism, probably under the roof's exterior sheet metal.
Just parked the Cayenne on a hill so the water runs to the passenegr side and all the water has drained away.
it seems clear that the drivers side drain tube is blocked so I will give the whole sunroof frame a clean up and see if I can find the blockage or if not feed something down the tube to free it. An air line may be usefull but maybe too powerfull.

I used something like https://www.amazon.co.uk/UEETEK-Stainless-Flexible... and cut off the brushes and just used the flexible stainless "spring" to clean the drain tubes on my M5. You're right to be careful with an air hose; you risk disconnecting the drain tube from the sunroof mech and then you're in a real pickle. Plus you may blow the muck everywhere! Loads of water and one of those springs used carefully and you should be OK.
BMW did something really daft; they put some sort of one way valve at the bottom of the drain tubes, presumably to prevent creepy crawlies from climbing up the tube? But with time debris clogs the valve and it becomes a no-way valve and water enters the car.

Ok thanks I have used a coiled wire as you suggested above but can only get down to somewhere behind the instrument panel.
There seems to be some obstruction that could be a pipe connector so I didn't want to force it.
Do you know if I remove the wheel arch liner will I be able to see and access the end of the drain tube?
I could try cleaning from the bottom up.
When I test both sides with a jug of water the passeneger side drains freely but the drivers side fills up and drains slowly drip by drip.
