Anyone have any updates I’m new to the leaking boot lid club 😀 Audi A3 convertible 2010.  Also added complication that the electronic boot catch has now stopped working, along with the nearside reversing light

Hello Anthea,

Welcome and thanks for joining.

Failing rear electrics - the car is old enough to potentially suffer from fractured wires within the flexible harness section twixt body and tailgate/boot. 
Not claiming this is your problem, but always worth a first line eliminator, before moving on to more complex causes. 
Perhaps you could let us know how you get on.

Kind regards,

Gareth.

Did you find out what caused the problem?

Hi all, I was having the same problem with water coming into the spare wheel area & around my Bose amplifier. I also tried sealing the lights, changing boot seals & trim. I finally found on my car that the water was coming in through a small venting flap located directly bellow the light units. This flap is designed to allow air pressure to be released when closing the boot lid, this vent overtime sticks open. when you get heavy rain the water will run down behind the light units & run through the open flap filling the area were the amplifier is located along with the spare wheel.Due to its location you will have to remove the rear bumper & replace with a new one from Audi. This has now solved my water ingress problem, I am please to say. Hope this helps you all. 
my model is a; A6 C7 SALOON 2015

Thanks for that information. I would never have imagined that such a vent existed.

Hi, any chance of the Audi part number for the vent, and any photos would be helpful of its location on the car. Great info. Thanks Ian
