Official exhaust software upgrade




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!

My car is neutered.




Thanks, man!

The Best of Mercedes & AMG
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.
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.

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

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.

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.

Worth pushing in any case!

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.
