Water under passenger footwell

[CoolC]

The cover itself under the windscreen doesn't keep water out of the cabin, it has drain holes in it after all.  It is a cosmetic cover for the plenum chamber below it. 

 

What often happens is that the drains in the outer corners of the plenum chamber get blocked with leaves and silt which allows water to migrate into the cabin. Not saying this has happened in all of these cases, but an area to look at when investigating.

Is it easy to access to check?

The dealer suspects the aircon as there is a known issue with the seals failing and the footwell filling with water. It's now booked in for a week to change the carpet, soundproofing and identify the leak.

 

It's worth periodically checking (there is a small flap in the carpet by the front of the passenger seat) as there was no obvious smell or dampness - but the soundproofing is saturated. Best to check while you still have warranty as this is going to be an expensive fix given the labour involved in striping the interior.

It's fairly obvious now it's leaking 

Fortunately it's going in tomorrow for a new carpet.

After nearly three weeks (!) at the dealers it's now back with new soundproofing and carpet. The leak was traced to some part of the bulkhead under the wheel arch. Water must have got in during a particularly heavy downpour. They could only reproduce the leak by firing a water jet in the wheel arch with the the wheel arch skin removed. I think this warranty claim could easily have cost close to £1,000 so worth checking your carpets before the warranty runs out.
