Hello, With all of the rain we had in April, my A6 allroad flooded. It has a full audi service history and has only don 41k. Audi Watford have inspected the car and have said that it has Â£3500.00 of repairs needed! They've said that the plenum chamber filled up and overflowed into the EC unit, which then overflowed into the cabin of the car flooding under the drivers seat and wrecking the ABS system and anything else thats placed under the seat. I can not believe that this could be caused by rain!!!! Has anyone else had this problem? Audi head office are taking no resposibility as they've said the car is over 5 years old. Totally gutted and I would never purchase another Audi if this is a common fault.
