Placebo? No. It is a significant change! A lot more backfire in S+ and Race. When reving it in "N" to 2.500 and lifting the throttle, the car does a lot backfire then - with my factory software from 11/2016, it did not (just as an example).

Hi Guys,


My car is going in the dealers this Friday as the stop start still isn't working.
What's the best "Problem" I should also mention to get this software update?

Spar7

Called my SA and was told too that they can't just update the software without a valid reason. So I just told him the car was jerky and they updated it.

Don't about you guys in the US but for my car always found it to be a bit jerky during certain shifts or when coming to a stop it happens randomly and I can't replicate it on command. Happens to me sometimes when I'm slowing down and coming to a stop at the lights or when I'm just cruising and gently accelerating

New software installed car feels smoother and yes exhaust sounds a tad louder and a few more pops

Which country are you guys in?
is this update available in us and Canada?

rbohgan

I don't know when my car was built but its a 16 model purchased in Nov. of 15. The car has AWE track exhaust so I have always loved the way it sounded anyway. Recently, ( the last few months) I brought the car in for an issue I cant recall what and they did a software update. I noticed after the update the exhaust not only sounded louder but when I upshift in race mode, I get 4 quick pops instead of 2. Is this what you guys are referring too? If so, I love it!! Recently bought a Prius to drive to work (please don't cut my nuts off people) but I think I'm going to start driving her again and park this P.O.S. hybrid.

That's awesome, I've asked my dealership about this and am waiting to hear back. Can't wait!

Toughen

Anyone in us or Canada did this update?

dforman15

Yes Toughen. Read the previous posts.

Toughen

no one mentioned where they from, and my dealer didn't know anything about this update...

Anyone know this service code for the update? Many thanks!

darwin329

That is what we all need is the service bulletin code.

I'm sure you guys that have had it completed have the code.

Please share!

Yes, that was me, my car has got louder and louder since then, don't know why, starting first thing in the morning it's unbelievably loud and I'm on the standard exhaust, I was going to get a sat map update but cancelled for fear of it going quite again after the software update.

tekfoc

Loud is good .

darwin329

when did you have the software update? I have 2015 edition turning 2 years soon.

Fordgt40

Software was updated November 2016 because of stop start problem, car is registered 31/12/2015, I don't have the build date to hand.

FDNewbie

THIS. Anyone know? Edition 1's (by definition) are very early production dates, so I suspect they didn't come with this software update.

My question is, if one were planning to get an ECU tune, would that tune affect this software update? I'd obviously prefer to do the update first then get the ECU tune, so I don't get my car flagged by MB as modified...

I used to have a Sept 2015 C63S saloon and now a Jan 2017 C63S Coupe and the Coupe absolutely pops and bangs more than the saloon - so ties in with the update logic it seems...

rbohgan

so i got around to calling my dealer- they said there are no recalls for my car a 2015 c63s sedan and said they cant just do a software update. she said bring it in and if the foreman can replicate the issue (jerky shifts...which i have just not all the time) he can recommend further diagnostic. so...this is gonna be annoying lol

Palpatine

That's very odd. My sedan is a 2016 and when my SA ran my VIN, he said there are 4 recalls.

Not sure what they were but he fixed them all when I had my software updated.

Mr. J

If this came from the service manager I'd find another location to get my service performed. Most software updates aren't associated with any recalls usually they are associated with a TSB so the above statement doesn't make sense.

rbohgan

I did buy car from them in feb...maybe they did it already?

good to know... i didnt talk to foreman she said I'd need to come in to do that. ill try and swing by later. thank.

Palpatine

Doubt it. I bought mine in mid January 2017... I don't think they do anything to them until they are purchased.
