Hello, This is my first post here and for anyone reading this thread I wanted to point out some descriptions that could be confusing, or at least confusing to owners searching for solutions to a different problem, also tied to a battery. The terminology here described the battery used for "Start/Stop" as the TSS (twin solenoid starter) battery. But it later migrated to "Auxiliary Battery" or "Aux Battery". Furthermore in the US there is a Technical Service Bulletin that calls the Eco Start/Stop battery parts as: "Dual Battery Junction Box - Part Number LR048786" I wanted to point out that there is another battery called the Auxiliary Battery. So for those with Start/Stop it could be called the second or third. Officially - the part number on my Auxiliary Battery is BJ32-19G207C-AA with the Land Rover label on top of what is a branded Power Sonic PS-1212 12 Volt 1.2 Amp. Hr battery which has uses in Home Alarm systems, powered wheelchairs, other uses. Current PS-1212 is 1.4 Amp Hr. I'm only jumping in because this was one of the first search results I found when searching for "Auxiliary Battery" and "Evoque" in Google - and I found other threads elsewhere talking about the Auxiliary Batter and confusing the two... (The reason I was searching is - error on startup - "transmission fault select park before engine stop" which I think is the same errors in other countries called "gearbox fault select park before engine stop". That battery apparently drives the rising transmission gear knob). Cheers, Bill
