2012 Mini Cooper S convertible. Replaced battery brand new, won’t start. At first it would start after disconnecting and reconnecting battery. There was clicking from passenger fuse box when it did start. Also air wouldn’t get cold. Now it won’t start at all. Tried to disconnect battery again reconnected wont start but trunk releases on its own and the dash lit up with car on lift. Then put the key in ignition to try to start, dash lit up with traction, brakes, engine, abs and several other warning lights. Can’t figure out problem. Dealer suggested it was because battery wasn’t reset, I reset on my own with ThinkCar Platinum S8 Diagnostic Scan Tool.

Your 2012 is a second gen car, and this is the third gen area. You will have more luck if you post in the correct area of the site.

The clicking relay box could be related to CAS failure. Mine is in the mid stages of it where the car will click like mad specially on hot days and the starter is not given enough time to turn over before the CAS loses it again and sends the car into a clicking frenzy
