C250 Exhaust Rumble
Hi I'm new here and I just got a fully loaded C250 coupe with AMG package back in November. I was wondering if anybody knows what that rumble is at WOT in S mode right after the car shifts. Do they all have that rumble or is it just mine? Either way it sounds awesome 
Thanks

C250 Coupe
Ya my bad, it's the sport package with amg rims. It's kind of like a groggy sound. I've been told it could be the intake but I'm not sure. On the 250's they use the turbo mainly for emissions purposes so it could also be the turbo system recirculating the excess exhaust? (Just a guess)

What I'm referring to is like a short "burble" immediately after up-shifting under brisk acceleration. Usually from 1st to 2nd and a small one from 2nd to 3rd. But as JCT knows, it's been so long since I've seen my car I can hardly remember what it looks like... Let alone sounds like.

C320 CDI
Hy
Hello from Romania !
When I bought my C250 CDI the dealer informed me about the posibility of buying a "Dynamics Package" which would add a SPORT button right next to the hazard/emergency lights (sorry for not knowing how it's called, the red triangle button).
Now...the thing is, he says, whenever you hace the SPORT button pressed a little drop of gasoline is released in the exhaust system, hence the small blurp you talk about.
I don't know if this is the sound you've been hearing, but it's what the dealer explained to me.

AFAIK the CDI's don't have that 'pop' on WOT upshifts that we've been discussing here, it happens only on petrol forced induction engines
I've recently (yesterday actually) driven just about all the CDI and petrol variants currently available from the MB stable on a race track (at an AMG drive day) and certainly no CDI was 'popping' on upshifts, the N/A C63 however was at times and also on it's rev matched downshifts, probably a product of unspent fuel getting into the exhaust.
I'll write up a separate thread when I get the chance on my experiences with driving some of AMG's finest machinery
