F30 Telematics Control Box Diagnostic
Hi All,
Have an F30 with the SOS Call System Failure showing on the dash. Replaced the telematics control box battery. The alert cleared for a week, now it’s back. Have access to a brand new Snap On diagnostic tablet so scanned for fault codes & I got B7F341, cleared it, stop / started the vehicle & the warning light disappeared. Stop the car, disconnect the tablet & at the next start up the SoS warning is back? Am I missing something with the fault clearing process? It’s a 2018 320d with 40k miles….. Any help appreciated. Cheers. Mark |

Ideally you'd scan with ISTA as that will tell you a lot more than a generic scan tool
I replaced mine recently and ISTA showed the fault and cleared the light no problem |
