Is there a problem with water leaks in the Audi A5 Cabriolet?

I have a 2012 Audi A5 Convertible and recently the Bluetooth connection for the hands free telephone has stopped working. I have taken it to my local Audi dealer and they have indicated that the problem is water ingress under the drivers footwell causing the Bluetooth ECU to fail. In order to sort out the fault they will have to strip out the carpet and take out the drivers seat to see where the water is coming from. They have quoted £1326.53 to carry out this work but I am not sure if this cost includes a replacement ECU. From my experience water ingress problems usually stem from blocked drain holes and I am fairly certain that I am not the first Audi owner to have this problem. The question is do you think an Audi dealer is justified in charging such an exorbitant amount to cure a problem that is probably a design fault.

There is a known fault with the A5 Convertible of the capillary tubes that drain condensation moisture from the soft top get blocked and the moisture simply drains into the car. This is a fundamental design fault with the car, but it's a 2012, so not a lot you can do apart from take it to an independent specialist who will work on it for a lot lower labour charge.
