Quick update, I picked up my car yesterday and had a decent time to drive it around to compare in all the driving modes.

I have previously owned a 2015 sedan and now a 2016 coupe. My Coupe is already a big change to the sedan, the pops bangs and the cabin noise in general. I decided earlier this year to have the secondary cats deleted, which was a pretty good decision. It made my car even louder.

This update has taken it to the next level... I had the 'ME' and 'Transmission' software updated - Took them about 3 hours for the update. When I went to pick it up I decided to drop it into spots+ and rev it in neutral.... holy sh*t! Previously there used to be one big bang (that was already loud due to deleting the secondary cats)... Now there are multiple loud bangs (even louder than before).

Driving feedback - Car drives the same in Comfort, no change. Sports+ and Race modes seem to be much more refined due to the transmission update (I assume). Gears change more seamlessly, there is no hopping and less jerking than before. The biggest difference however is the noise. Downshifting gears have multiple pops, which was never the case before. Also, when driving at a steady speed and letting go off the gas you can hear multiple loud bangs go off. I had people looking at my car (more than usual).

I was hesitant earlier this week after reading someone having issues with their update. I can happy vouch this update is EPIC to say the least and anyone who feels their 2015/16 models don't need this update... all I can say you don't know what you're missing out on. It's free, why wouldn't you get the most out of what you've paid for.

Will get some videos for you guys over the weekend!

I'm jelly.
My car is neutered.

Sanch

Sorry to hear mate, that is just not acceptable. I would take it back and have them run a full diagnostic on the car and let them figure out the issues. If it's under warranty it should be a burden on their shoulders.

auditoamg

Exactly!
Thanks, man!

Hey Sanch, I've been keen to do this as well and as my car is going in for the diff oil change next week I might try and get it done. What am I actually asking for from the dealer to get him to do this for me, my car is a late 2016 build. Cheers mate.

Sanch

Hey Mate, that would be ideal. I was straight up with them, I told them I felt like my exhaust note seemed lower than usual and I had heard on the forums that there is a update that fixes it. All they had to do was search it and they found the exact update. Doesn't take them long at all either. Good luck, don't think there will be an issue.

So weird how different dealers have behaved with this update. Some act like you're asking them to give away their children!

Aussie Zinga

Thanks mate, I will give it a go, much appreciated

I have now done about 600kms after the software update (+ annual maintenance).
Sport+ and Race nice cracks and pops - eg. second gear, 40->55KM/h, 3000rpm, release pedal, 2 loud pops.

However in Confort and Sport, no cracks or pops during downshifts. During rapid acceleration in Sport, Sport+ and Race clear bang between the gear-changes.

I took my car in yesterday (dealer Orpington Mercedes)

They claim the update applies to cars built before December 2016.

The bulletin says UP TO December 2016.

My car was built on 13 December 2016, what do you guys think.

2 things to check out on your car to determine if you need the update Uga. How 'lively' is the exhaust and do you find that the transmission is jerky when at low speeds in sport+?

When I say lively; put the car in sport+ then accelerate and lift your foot off the gas at different revs from 2.5k upwards. from 2.5-3.5k you should get 1 or 2 pops and crackles when you lift your foot off.
Higher than that and you should get an almighty crescendo of really loud pops and crackles

Alternatively you can follow the same process but rev the car from standstill.

If you don't experience any of these and your transmission feels jerky then you need the update

Andyroo

Sounds pretty clear cut to me unfortunately. Up to December doesn't include December. You could try harassing them (nicely) until they try it anyway, but I doubt they will.

Uga Uga

Thanks for your response Trim.

My car is also in for a 'Jerky' 3rd to 4th gear change, as well as a something very strange with the bonnet/hood alignment.

The bonnet/hood seems ok all round front edge and sides, until it meets the 'A-PILLAR.

One side has a gap of about 2-3mm, the other has virtually no gap at all, Fender to door gaps also seem ok.

Thanks Andy.

I will get clarification from MB Customer assistance centre in The Netherlands.

On the issue of UP TO, If in an exam I was asked to count UP TO 3, and I said 1, 2.
my answer would be wrong. perhaps my logic is flawed.

Or say, you are asked to count the months UP TO December, leaving out December will not be correct.

Andyroo

If you were told to walk up to the wall, you wouldn't walk into it though

Worth pushing in any case!

BallzOne

I would say if it included December the bulletin would say "through" December.

Same body panel issues here...

Uga Uga

Thank you gentlemen.

Uga Uga

Hi AuditoAMG

I'll let you know what they say about the uneven gaps.

ezatnova

Please follow up in a PM or new thread. Body gap discussion doesn't belong in this thread.

Uga Uga

Thank you. That is my plan.

auditoamg

Thank you!!!!!

Update.

Trim you were spot on mate.

I picked my car this afternoon, and YES the engine and transmission software needed updating, and so it was done.

I now get multiple crackles on lift off. It used to be just the one.

Throttle response in S+ is now more controlled.

Exhaust sound in S+ is deeper with more crackles.

Only downside now for me is in comfort with performance exhaust on:
The car sounds quieter. It used to rumble and sound deeper before the update.
I suppose what it means is the parameters between comfort and sport+ are now wider apart.


3rd to 4th gear changes now seamless.

Interesting thing, I just got a call as I was typing this from AMG, following up on my complaint.

Thank you all once again.

Good for you guys, I just visited dealer today, they still keep saying this update is not for Canada...
