Got this upgrade after my 2K rear differential replacement. I notice now that with the sound more prevalent now. The pops and gurgles are louder in Sport+. I am also getting better mpg in Comfort w/ Auto Start Off, when I am driving longer distances.

 

Hate to revive threads from half a year ago but I don't think this issue has been addressed. If I already have a tune on the car would going for the update remove it? Thanks

 

 

asked my local dealer for this update today while car is in for service, they said they can't do it since there's nothing wrong with it...so sad!

 

Listen I went in for a Service A and this is what I said.

"I want to do a Service A and there is an issue with the gear shifting in Sport + mode. The shifting is kind of jerky between 2nd and 3rd gear or between 3rd gear and 4th gear. Also the exhaust is sounding kind of weird. It's does not sound correct. Sort of like a canary bird (SA laughs). I have this Sentry bulletin (bring in the paper) where this issue has been brought up and there is an update to the ECU and transmission for this (SA opens eyes big and calls in foreman since he doesn't know what to do)."

Foreman agree's he will take a look over the issues and update if necessary. No more questions asked... I even mentioned the Navigation update for 2018 and it was also done (if you don't ask they won't do it).The foreman was brought in and said okay there is no issue and we will update it if it's showing on the computer. If you don't say exactly what I said above, you better have a connection, friend or good SA that will help you out, because without a complaint they will not do it... unless that dealer is chillin.

Listen go to another mercedes benz dealer and go in as if there is a problem with the transmission and exhaust. They can't charge mercedes benz (warranty issue or software issue) if you go in for a simple update that not mandatory. They need to have a complaint to charge headquarters for their time. No free b's. I bought my car in carmax January 7 and went in for the update January 14. About 1 week after purchase and they never questioned me. I suggest you don't go back to the same dealer for the update... If you want to guarantee it. Try going in for a service since they make money on this and they might bend over for your complaint of the sound and transmission. If they don't just tell them, it's too expensive for the service and you will take it elsewhere. My car was serviced at carmax in December few months prior to purchase and I still went in for a Service A to achieve the sound update. Totally worth my $460 Service A. , tuned ECU, sound update, and map update, + service (totally worth it)

Good luck.

 

Nice...I will try that

 

If you take the time to read even just the 10 posts prior to yours, you would have your answer as to what to say or do.

 

Lol...I did and dealer still refused. I'll try another dealer.

 

 

 

Does anyone know the vehicle production cutoff date for the latest software?

 

Is there any way with command to check version?

 

December 2016 builds and onwards came from factory with latest software.

 

 

I am told this turned into "W" bulletin which means its applicable all around the world, not just specific region.

 

After all their hesitation, they ended up installing it (along with the steering column recall). Sounds much better now!

 

 

Picked up my 2016 C63s a few weeks ago and utterly love it however want a little more volume.

Ive read this thread with great interest and have contacted my dealer for the upgrades, like many in this thread they had no idea what I was talking about however they were helpful and willing to help out if possible. Just heard back from them after they looked into it and they say they are happy to upgrade all software to whatever the latest release is. My question is simply will this latest update incorporate the specific sentry update referenced in this thread automatically or do I need to ask them for this exact update?

would appreciate it if anyone could chime in, UK dealer if it makes any difference.

thanks...

 

Does anyone know if this update is relevant to newer models?

ive sold my 2016 C63s and looking at coming back with a 2019/2020 C63s or glc63s. I miss the power and I definitely don’t want to miss the exhaust popping that came as part of this update!

 

anyone able to answer this? Thanks

 

The updates are cumulative, so the latest one will include all those before it.

 

Thanks a lot, booked up for service and all available updates next week so hopefully will hear a difference!

 

I'm bumping an old thread but I'm going through this now with my new car. My car is a 2017 and I took it in for it's first service when I first got it three weeks ago, when the SA ran my vin to set me up a file for the car she noticed there was a single ECU update. I denied it at the time for other reasons, which I probably shouldn't have. Either way, would this update come up when just running the cars VIN when in for a service, or is this something I'd specifically have to ask them to go find out about and install. I asked the shops foreman about the update and he had no idea what it. The SA gave me a print out(below) but it seems to differ from the numbers I'm seeing listed in here, although maybe it's different for each country - I'm in Canada. My car had never been in a dealership since new FWIW.

 

Anyone have any input? Trying to figure out of this is something the service advisor would see as an update to be done based on my VIN, or if I have to actually find a service advisor that knows what this is.

 

Get your SA to put in the effort and look up the descriptions for you.

Different NT countries have different identifications for the same update. We confirmed that a few times in this thread ie: US, Australia, UK all have a different ID but same description

i want this update for the GLC63. I notice a huge difference (lack of) lift off backfires compared to my 2016 C63s that received this update
