Mercedes B Klasse Audio System Failure

My 2023 Mercedes B Klasse with a diesel engine has a completely dead audio system The display is dark and silent I scanned it and it shows an error in the error memory related to the audio system Could it be a defective head unit Has anyone else had a similar Bluetooth problem or speaker crackle before it died completely

I had a similar issue with my B Klasse Diagnostic pointed to the display needing replacement What is the precise error code

I don't have the exact error code right now Did your audio quality deteriorate gradually or did it just suddenly fail like mine Was your eventual repair cost also pretty high

The audio system failed abruptly The error code is essential for an accurate diagnosis Based on your description a defective display is the likely cause I suggest consulting a certified workshop for further investigation

I took it to a workshop and you were right the head unit needed replacing Cost me around 725€ which is painful but at least it's working perfectly again Hopefully no more static noise or Bluetooth problems now
