It looks like the entire plastic piece that runs the full width of the car and goes under the windshield wipers would have to be removed. And it appears that this pieces actually has a semi-permanent seal to the bottom part of the windshield. Does anyone know how to change/access this secondary battery? I haven't been able to find it in the service manual.
When did the Evoque add the Eco auto start/stop functionality with the secondary battery and twin solenoid starter? My service manual claims to be a 2015 but it doesn't mention the 9 speed transmission so it is obviously a 2013 or older manual. Since I can't find any mention of the second battery, the start/stop or a twin solenoid starter in the manual I am assuming it was added in 2014 or later.

So if your Eco start stops working it’s may be because the secondary battery has failed? Is this a dealer only part? Haven’t run across it in my search for a replacement primary battery.
Has anyone seen a good step-by-step procedure for replacing the primary /secondary battery?
