I can hear water sloshing back & forth as I accelerate & break. The sound is from under the passenger seat. I have seen several posts about this - I have a right hand drive CRD model - I can find drain plugs under the driver side but can't locate any under the passenger side? - Does any know where they are on my model? Thanks - - -
Thats what I thought it might be. It sounds the same with fuel light on & when the tanks has been filled right up. It just sound like a half full water bottle being sloshed back & forth under the passenger seat.
There was an issue on some GC's with water getting into the compartments under the front seats. Motor the seats forward, open/remove the access covers and check for water in both the battery and opposite seat compartments.
There is a water leak TSB showing areas where water can get into the GC passenger compartment:
