Hi Just about to replace the main consumer (rear) AGM battery in my CLS55. Anything to look out for apart from remove neg first then pos and reverse for refitting?
Thanks

You will need to resync the windows and sunroof and the ESP.
"Synchronise the ESP®. With the vehicle stationary, turn the steering wheel completely to the left and then to the right to synchronize the ESP®"

It's all in the handbook

I connected a battery charger to the leads before taking them off, that way no resetting was needed.
