Audi a5 not starting

[Paul Attrill]

Hi, I wonder if someone can help or point me in the right direction. 

My Audi A5 is not starting up. There was an issue with the electronic hand break which seemed to drain the battery. Now it seems as though the whole back half of the car is not working. I thought it might be the control panel in the boot as it seemed to be making a clicking notice but that looks ok and now the clicking has stopped. I've checked all fuses and now just stuck

Please help

Hello Paul,

Thanks for being in touch. 
Probably a daft question, but we take it you’ve had the battery efficiency checked and it’s been proved to be serviceable? 
Kind regards,

Gareth.

The battery is holding charge above 12v. Recently recharged it.
