Hi Robbie & Melzonk,

I have the same issue - Auxiliary Battery Malfunction

Please excuse my ignorance - could you point me at the location of the Fuse board and Fuse 448 - are Spare fuses included on the Board?

Thanks for your assistance.

Tony

Update

Removed fuse 448 - Not blown
Refitted the same fuse - No Warning message 🤔
Very strange - Fingers crossed 🤞

Update - 5 days since removing then re-inserting fuse 448 and no Auxiliary Battery Malfunction Error messages 👍

My 2016 GLC has just started with the auxiliary battery malfunction error message. I intend to check the fuse 448 first. The vehicle has always had issues with the eco stop/start function with the battery replaced under warranty in less than 3 years. I trickle charge the battery now if the vehicle is not used for a period of 2 weeks.

Tony Mac - can you advise if the Auxiliary Battery Malfunction Error has been resolved on your vehicle?

 

[Tony Mac]

Yes - after simply removing and reinserting fuse 448, the warning message has not returned 🙏

Thanks for the information, I will check fuse 448 first. 👍🏻
