F54 - B47 Engine, no faults but EML
F54 Mini with B47 Engine. ISTA reports no fault codes except 12v battery needs replacing, yet EML is illuminated.
Regen'd DPF as needed doing but no change. Any suggestions? Author of Car Connector - remote ICOM & ENET tool - Built in VPN for easy coding and remote diagnostics Closed Beta in progress - Open Beta starting Jan 2024. |

Did you replace the 12V battery?
If the battery no good could displayed a lot bogus faults. |

Why not double click on the fault code? It should give information if it triggers warning light.

So, thanks for your advice, I'm grateful.

RE: F54 - B47 Engine, no faults but EML
I agree with larshutten. Why not just open fault details and see whether it triggers warning light. It's normally stated right there in the fault description.
