Open the full vehicle complaint log (all categories)MY 2005 AUDI A6 HAS WATER DAMAGE. SOME HOW OVER NIGHT HEAVY RAIN SEEPAGE LEFT AN INCH OF WATER BEHIND DRIVER SEAT. CAR WAS PARKED IN DRIVEWAY AT A SLIGHT INCLINE. ALL WINDOWS AND DOORS WHERE CLOSED. THIS HAS CAUSED $2,700 ELECTRICAL DAMAGE TO MODULES LOCATED UNDER FRONT PASSENGER SEAT. THESE MODULES ALERT ME ABOUT ESP/ABS AND PARK BRAKE AS WELL AS A MODULE THAT POWERS THE VEHICLES MMI/NAVIGATION AND STEREO SYSTEM. NONE OF THESE FUNCTION ANYLONGER. I DON'T KNOW WHERE THE WATER ENTERED MY VEHICLE. IS AUDI RESPONSIBLE? THIS APPEARS TO BE A DESIGN FLAW. *TR
MY AUDI A6 STAYED OVERNIGHT IN THE RAIN. IN THE MORNING THE DRIVER'S FOOTWELL WAS FULL WITH 2 INCHES OF WATER. AUDI RECOGNIZED THAT SUNROOFS HAVE A DRAIN LINE THAT IS INSTALLED WITH A KINK TO LIMIT NOISE GOING BACK INTO THE CAR. THE PROBLEM IS THE KINK PREVENTS DEBRIS FROM EVACUATING CORRECTLY. *TR
DURING A RECENT RAIN STORM I WENT TO START THE CAR TO DISCOVER 6 INCHES OF WATER IN THE BACK SEAT. REAR AIRBAG AND SOME ELECTRICAL SYSTEM HAD BEEN FRIED. WHEN I CONTACTED AUDI THEY SAID THAT IT WAS NOT A WARRANTY ISSUE THAT IT WAS MY FAULT. THAT A LINE UNDER THE BATTERY COMPARTMENT HAD BEEN CLOGGED BY PINE NEEDLES CAUSING THE WATER TO FLOW INTO THE CAR THROUGH THE AIRCONDITIONING SYSTEM. IT SEEMS TO ME THAT THIS IS A DESIGN FLAW AND SHOULD BE COVERED BY AUDI. *TR
