Response from BM Cars service

The problem you described suggests a malfunction of the radio or amplifier, which is part of the radio in the standard version of the E60. It is necessary to check the audio system on the diagnostic side and eliminate mundane faults related to improper removal of door upholstery or speaker installation, or even moisture leakage through the door soundproofing.
