Is there a critical voltage below which the car will not go into ready mode?

probably around 11.8 V but ideally you don't want it to drop that low as if will be quite heavily discharged at that point, causing damage to the Battery in a reduction in usable capacity. Even at 12.1 V it means the Battery has discharged over 50% which isn't good and it only taking 2 days to fall that low probably indicates it has lost some of its capacity already.

After monitoring the resting Battery voltage for two weeks I changed the Battery this morning. It was a fairly straight forward job. No error codes or messages after the change. The old Battery was a Panasonic the new Battery is a Yuasa YBX5027 sealed Battery from the local GSF car parts depot.

Hi Iain, good to know that the change was completed without any issues, always a potential problem in today's vehicles. Keep us up to date with future progress please. Mike

Hi David

How did you (or the AA) manage to get to the Battery? With no, or low, Battery the boot can't be opened as there is no mechanical system (as there is for the doors). I have had the same problem and the AA man had to wiggle his way via the back seats.

There is a charging point to jump start them in the engine bay, no need to gain access to Battery.

Details are in the handbook ,showing the correct places for each lead.
