S63 Coupe
Missing Sound - Amplifier Issue?
Hey there,
Long time lurker first time poster!
Was wondering if anyone could assist in this issue as my local garage is unable to figure out a solution.
I recently purchased a 2016 S63 coupe and around a week ago I had sent it in to get strut rods replaced as well as an AC filter change.
When I got the car back I noticed a huge chunk of the sound frequency missing while listening to my usual selection of tracks.
It would seem that a vast majority of the mid range frequencies are barely audible i.e. 250hz - 3000hz
I've run a tone generator sweep and its glaringly obvious that this chunk is missing.
I immediately called the garage and they said to bring it in. Once checked they agreed theres an issue however they were unaware how to solve it as none of the cables/speakers were disconnected.
The only solution they could provide is a software update for command which they couldnt do then anyways because of this COVID 19 situation in germany.
Would really appreciate some help if anybody here has experienced similar issues. Could it be a faulty amplifier?
I might add that I have fiddled around with the EQ settings/auto volume adjuster/surround sound settings and still the issue persists. I have even tried -10 on the treble and bass to isolate the mid frequencies however when I boost them to +10 the gain is minimal.
Regards,

That's very interesting! I just bought home an used 2014 S550 4 Matic with the Burmester 3D sound system.
And, I too just noticed over the weekend that the rear back door especially the rear right as well as the speakers in the dash behind the headrest are not working.
Were you able to figure out what was your issue as well as the solution?
Regards,

I had a problem, and they have a diagnostic program they run thru the system which is supposed to tell them anything that is wrong. I would take it to mb and let them figure it out.
