It appears you have not provided sufficient instruction to son before
turning over responsibility
for care and feeding of S4. If the car is to be exposed to the
elements, the plenum drains
under the hood must be kept clean or cold feet will be the least of
the problems. It could be
a condensate drain under the evaporator coil, but the most likely to
send water to the drivers
feet is the plenum has a significant amount of water trapped in it.
If that is happening, the passenger side is undoubtedly wet as well.
A significant amount of
water can be held under the carpet in the cable runs and foam before
it is obvious, especially
when there is no passenger to notice the rising flood. The ECU is
perilously close to this
water and getting it wet when power is on is known to kill it.
We have had the kind of rainstorms recently that will flood a plenum
with clogged drains in
just an hour or so. If the floor is wet, don't turn on the key until
