I'm in a bit of a bind here. Parked my E-Class in the DIFC this morning for a meeting and when I came back, the car was completely dead, no lights, no central locking, nothing. I managed to get a jump start from a colleague, but now the dash is lit up with warnings and the start-stop system isn't working, which I know is a sign the battery management system is confused. I've heard that with Mercedes, just swapping the battery isn't enough; the car needs to be told a new one is installed, otherwise it keeps using the old charging profile and can overcharge the new battery. I'm looking for a service that can do a proper job with the registration and coding. I've seen a few options online, including https://batteryzoneuae.com/mercedes-battery-replacement/, which seems to offer the full service with genuine batteries and on-site installation, but I'm not sure how long it would take them to get to me in the DIFC area. Has anyone used this kind of service before and can tell me if they're reliable and quick? I really need to get this sorted today before I end up stranded again.
