My car is a Japanese import into Australia,

Is this annoying 'bong bong bong sound standard in this model or is it a Japanese thing when you select reverse?

 

Sounds like the "Backup Warning" signal typical of a delivery truck. Maybe Japanese Wagon builds are classified with trucks?

To answer your question, it's NOT typical for any E-Class in the States, sedan or wagon..

 

Hmmm...That sound is supposed to happen only when doors are open and the vehicle is in gear to warn the risk of roll-away.

 

That sounds much better than my response. Thanks a lot.

 

This sounds will come while driving with seat belt not buckled up.

 

Another good suggestion... And, in your other thread, Is see you're having problems with an airbag.

 

Seat belt on, door closed...sound is only when reverse is used.

I'm hoping Benzninja can delete the sound...please!!!!

 

I think coding should make this go away or deactivating chime module too . However, it's not that annoying as much as I find in Rolls Royce Silver Spur / Spirit / Dawn Series when you start the engine

 

yeah not off to a good W212 start to be honest, hoping the AirSpring is an easy fix and the Hidden Menu might have a fix for this damn noise.

 

It is the seat belt chime sound and that would drive me nuts if it happens all the time when reversing. Definitely get that remedied

 

If it is the seat belt chime, I would connect all the belts to see if the chime goes away. If it does, then start disconnecting the rear belts (one by one), then pass. front... until the chime returns. That will give you an idea of which belt causes the problem.

If it's the rear seat belts causing the problem, remove the rear seat bottom and test some more without the seat in place...

 

The seat belt chime is easily disabled with Launch/Star/Whatever tool you have that can converse with the car.
I bet the reverse chime is as well, but don't have personal experience.

 

Hey guys just a quick post to say Benzninja fixed the issue, the guy is a master at his craft 100%, can't thank him enough for his help!!...silence when reversing now!!

 

Kudos to him , nice job

 

Hi guys, a bit of a shot in the dark here but I have the exact same issue on my 2010 E350 Japanese import
Does anyone know what the fix was for this noise?

 

That is a Japanese spec mandate

 

This is done through a variant coding... likely the gateway that stores most of the chassis configs.

 

Thanks for the reply, can this be done via an SCN code in the parktronic control module? or will I need to find a third party who can re code.

 

It's easier than SCN unless you can fetch the firmware files necessary to match config you need.

If you can't do it,
get it done remotely to your liking.
