From VX forum , dont know if it works or not .

" The reason and cure for ‘wet foot well’ on both passenger and drivers side of the Vauxhall Combo van and the Corsa ‘c’.

Passenger side:

The foam seal around the main electrical connection unit lid, in the near side corner of the engine bay degrades and lets water in. Remove this using the torx screws, push out out the foam seal with a flat blade screwdriver. I recommend using Wikes’s Acrylic Roof Repair. Product Code: 243816, Apply a thick bead in place of the foam and replace lid. Then use some more sealant to seal around unit. This should sort the problem.
If it persists to leak it will either be the electrical connection unit cowling to bulkhead seal, this is a rubber seal and you will need to disconnect the wiring loom plugs between the outside and inside beneath the lid. I recommend pulling the rubber seal out and cleaning it then replacing it in its groove then applying a bead of gunk on the seal then re fixing the cowling. The other reason may be the heater intake seal leaking. (Dough full though) remove the intake. The seal is foam tape. Spread a bead of gunk on this and replace.

Driver’s side:

The brake servo and brake fluid reservoir are mounted on a black bulkhead plate. This is secured to the bulkhead via 5 or 6 no. 13mm nuts within the engine bay and wiper bay area. The factory seal breaks down as its only thin. Remove the nuts and working inside under the pedals, lever the plate down. With latex gloves on use handfuls of sealant to thumb in and around plate, then refit. You could just smear sealant over the plate to bulkhead joint but this may not guarantee a fix as it is very awkward to get to the lower area under the brake servo unit. From the outside thumb in sealant over the join and where pipes ect. Penetrate the plate. All done.

Hopefull this should sort it. It did for me."

Suggested Solution

Hi know this is an old post but will answer it for other people with the same proble who drive a corsa c combo van or tigra. The most common problem on water entering the drivers side is nominally caused because of breaks in the sealer on the brake servo plate. The best way to repair this is to remove the servo to allow you to get proper access to the plate so the sealer can be removed and the plate can be cleaned. I use a primer and a polyurethane sealer to repair the ones I do. The servo it's self has a gasket we do always do away this gasket and use a soft sealer that never drys so should you need to remove the servo again it can be removed easily. We have also found water entering via the bonnet release cable geometry on the servo plate. Other places to check is water entering the sills on the car via the door seals best way to fix this is to remove one of the grommets in the sill. If you have side skirts the grommets are locate behind the skirts. For more information on other places to check you can lookup betta windscreens on google or visit www.bettawindscreens.co.uk they offer a repair service for this problem in the U.K.
