SOS Battery Replacement
Hi
Can anyone point me to a guide/part number on how to replace the sos battery in a 2019 G20 saloon? Started getting the messages on the dash today (did say it was low at my last service) so it's probably time to swap it out. |

I believe the battery is located under the shark fin antenna. You have to remove the headlining to get to it - usually a dealer job, but there are videos on YouTube showing the replacement if you are feeling brave.

Thanks for the advice. Looks like the issue has gone away now after a bit of a drive. It was flagged as being low during last service which is why I'd assumed it had gone

SOS Battery - Became a bigger deal
Have a SOS battery issue with my 2017 340i, at the same time the GPS has stopped working. The car is at the dealer, turns out the TCU and antenna have water damage. It get's better.... 2 years ago the car was in for an oil change at the dealer, the car is black so I ask for it NOT to be washed. The porter washes the car and the machine dents the roof 8" away from the shark fin. The dealer repairs the roof. (the car is not driven much and is garage kept) Back to the SOS and water damage... The dealer can't get the shark fin to reattach without it leaking do to the roof repair. They are willing to pay for the replacement antenna and part of the labor but not the TCU. I will be fighting with the dealer on this repair that was caused by their car wash. Any advice??

I contacted BMW UK and within half an hour it was all sorted. I would suggest you give them a call because the dealers can be very slippery when I comes to coughing up for stuff. |
