Rear passenger floorboard is flooded.
leaking water from drain plenums most likely cause of Transmission Control Module failure. Car sat at dealer for 2 months while they waited for authorization from Audi USA to repair it without charge. They never told me it was from water damage, because of the drain plenums clogging. will look up mileage when this occurred
