Thank you for your response. When you experienced a similar situation, did the error messages specifically mention the auxiliary battery? And did you observe any other electrical malfunctions beyond the starting issues, such as problems with the lights or infotainment system? I would appreciate further information.

Yes, the error was definitely related to the auxiliary battery. I cannot recall specifics about other malfunctions, but I would assume it is possible. I strongly recommend seeking assistance from a qualified mechanic to diagnose the problem accurately. It seems like your car electronics are acting up. Best to avoid further damage. I hope this helps.

I appreciate the advice. I have taken the vehicle to a certified workshop. They have confirmed the need for a battery replacement of the auxiliary battery. The estimated repair cost is indeed 290€. Thank you for your insights.

Sorry to hear you are experiencing difficulties. I also have a CLA and recall encountering a somewhat similar situation. The error message and starting issues sound familiar. I am not entirely certain about the voltage drop aspect, but it might be connected. I would suggest examining the battery connections. If you aren't skilled at electronics, I would advise professional assistance.
