do a lot wadeing get quite a ot of flooded roads round here and often there isn't another way round.
1) decide how deep it is
2) work out where your air intake is , sometimes if intake really low you can pop the clips on the airbox to effectivly raise it.
3 ) drive in make a decent bow wave and keep up with it
i've had quite a few cars with there headlights under water, but its getting dodgey then you know that if you stop it's bye bye engine
