You just need to switch the wires on the end of the one pin connector. No need for an attenuator - avoid the nightmare. Jehnert also makes a $27 cable that switches it for you but they don’t ship to the U.S.
That is absolutely correct! We added the attenuator prior to Mercedes announcing that they manufactured the speaker pig tails incorrectly. The official fix is at the end of the video and is super simple to rework. Less than 5 minutes effort if you have a dental pick in your toolbox.
One more question after doing the wire swap: Do you see an "SOS unavailable" message illuminated in red, then turns off after 15 seconds? - I see this on the main MBUX screen at the very top edge on the right, where a few other small icons are displayed. For additional info, I have a 2022 MB, 2023 Revel. Thanks for your help! Switching the wires into their proper connectors has made a huge difference in sound- my only concern is the SOS function.
Hey Catherine, good to hear the wire swap went well and the stereo sounds better!!! The “SOS Unavailable” has nothing to do with the speaker wires, no worries! You get that message when you turn the vehicle on and it is connecting to the over air link or the vehicle has lost the connection (ie in a tunnel for a while). The red light near the SOS button on the ceiling is also illuminated during the sync process. You probably didn’t notice the message before, it happens on all Sprinter vans when you start up the system. Again, awesome job on the swap!!!👍
Does the wire position matter if doing the “official fix”? For example if green is on the left of the wrong clip, should it be on the left of the correct clip when I make the swap? Thank you in advance, and thank you for posting this video!!
Hey Catherine, yes! You should keep the colored wires in the same position (i.e. green to purple position and purple to green position, gray to gray). If you cross wired them then the center speaker would be out of phase with the small left and right tweeters and the door speakers. It’s purely a sound quality issue if the wires are crossed. Great question and thanks for watching the video!
Wow i switched the wires and what a difference. You should have just started the video with the real fix instead of the bandaid approach. But still i thank you sir ❤❤
Yes, swap the wires front to back, back to front. Keep the same wire orientation (grey wire to grey wire, colored wire to colored wire) or the center speaker will be out of phase with the other speakers in the van. Thanks for watching the video!
LOL, noise cancelling head phones also work!!! How this problem made it through Mercedes QA for over 2 years is beyond comprehension? Driving out of the Dealer parking lot from picking up the van we noticed it and wanted to turn around, it sounded so awful!
@milestonesprintervan-peter9545 2 years? Try at least 5! I had a 2018 with the issue. There was a MB tech bulletin in 2022 addressing the issue. I now have a 2023 with the exact same deficiency. Go figure.

Great video, thank you! I’ll be doing mine very soon!
Thanks…this was exactly the info I needed!

@@milestonesprintervan-peter9545 You're right, I hadn't noticed before, but was paying close attention after making the wire change!👀

Thanks for watching! We are really happy with the fix! Too bad Mercedes doesn’t reach out to repair the affected vehicles. 👍
Is there a reason you need that speaker? Thank you.
I think mercedes issued a service bulletin so this component isn’t needed. Four wires need to be swapped. LI82.85-N-071147
Yes they did after we installed the attenuator…. It is discussed and detailed at 4:35 in the video.
so the 2 wires in the white now go to the black connector and they go in the same holes on each one?
Yes, swap the wires front to back, back to front. Keep the same wire orientation (grey wire to grey wire, colored wire to colored wire) or the center speaker will be out of phase with the other speakers in the van. Thanks for watching the video!
@@milestonesprintervan-peter9545 Thanks! On the to do list for tomorrow.
Here's a quick temporary fix.
Put a folded towel to over the center speaker.

2 years?
Try at least 5!
I had a 2018 with the issue.
There was a MB tech bulletin in 2022 addressing the issue.
I now have a 2023 with the exact same deficiency.
Go figure.
