Under bonnet - removing bulkhead/scuttle panel access covers

[DCPU]

These two:


One plastic 10mm nut (mine stripped on offside) and two clips on the inside edge:


And an extra (easter egg?) lambda on the offside with great access to the wiper motor:


And access to the air intake/heater on the nearside:

 

[DCPU]

On the offside there appears to be some form of sealant over the (badly fitted) fir tree cable clip. I wonder if there's been an issue of water ingress onto the wiper electrics/motor?:


Whilst no evidence of any sealant on the other side:

A great help for future! thank you @DCPU !
The heater access on the nearside is reminiscent of similar access for the RangieP38... which used leak until I fabricated a bunding around it as per what's shown here! excellent!

Despite all the cover and foam seals - there was more than a fair amount of tree debris sitting in the scuttle - not sure how all that was getting in?

Another noteable whilst in the area, a nice tidemark under the bonnet seal:

And anyone with water ingress issues may want to see if they have two areas where the the bulkhead seal appears to sit away from the bulkhead:


* Not sure why photos are portraits, they were landscape and illustrated the gaps better?

@Jean Mercier Could this be your water source?

Thanks for the suggestion, but I would say no, because the water comes out of the lateral air vents, and these are situated higher than that seal.

Looks like the water just goes straight through to the air vent. I mean, you can see the a/c condenser through it.

That's the cabin air filter, not the condenser... And that is exactly how it is on many (most) vehicles. My Sprinter is the exact same way, except it has a giant air duct guiding air towards it. The lips around the opening will keep water out (unless, of course, you are driving in water up to the windshield, but you'll have plenty of water intrusion from other places at that point)

But as pointed out, there is a lot of debis around the intake. Maybe getting some mist when driving in the rain?

I doubt it very much; the debris is very clearly in the tray area; additionally, it's not out of the ordinary (on all vehicles) to get some leaves/etc on the cabin air filter when you're replacing them
