Has anyone had a leak in their S4 where the drivers foot well fills up?

Does it have a sunroof? If leaking the water can travel along the roof to the A pillar and then down into the floor pan.

No it doesn’t have a sun roof. Previous owner had it garaged so never knew. But when cleaning it it never leaks

Check the battery tray area. Common for the drain bung there to get blocked up. Also the A/C drain pipe could be causing it

Had it happen on my old B5 A4.
Blocked drainage hole on the little bit of body panel near the windscreen on passenger's side.
Only happened when parked on an incline.
Real bugger trying to dry the insulation foam in the footwell.

Super Super Common on the B5 A4 & B5 Passat
The two drain plugs clog up & the water then makes its way into the car. Most people don't notice until its too late & start getting problems with either the central locking and or alarm and or the transmission on (Automatic cars)  can start doing funny changes . This is because the control units for these are located under the front seats.
( Open them up & make sure they are dry inside otherwise issues will arise later when the terminals start to corrode)

One bung is under the brake booster ( reasonably easy to get too ) & the other is under the battery so this has to be removed along with its mounting plate & you will then have easy assess to the bung.
I would clear these both out once a year every year when I had my A4 & Passat & you will never have the problem again. I always did it at the same time the car was in for its annual service as part of the service   

If you own a B5 or B5.5 , just do it & do it now, this effects ALL of them
