2005 c230 ss gas pause
I just got a 2005 c230 ss 6 speed and i have noticed that in first gear when you hit the gas to the floor there is a slight pause. Can anyone tell me why this happens.

The same thing happens on my automatic '04 C230. Also, there is sometimes a slight hesitation when the car shifts from 1st to 2nd when the engine is cold. I had it checked out during Service A and they said it is normal.

Then again - there is nothing wrong in revving the engine to high RPM - it certainly is much better than underrevving. Just don't floor it when it is brand-new.

This is actually a known issue discussed before on this forum. It's more noticable on an auto tranny but you can still feel the lag respone in a manual tranny too. Spoke with service advisor and MB purposely programs that throttle lag into the ecu, there's pratically nothing you can do about it -- unless you get a performance chip which rids of the lag.
Do a search for throttle lag/pause and see what others done to cope with it... Pretty much performance chip upgrade to fix that.
I was thinking an ecu upgrade as well, hopefully to fix that throttle lag and give a few extra ponies in the process...

My E320 does that and was told by 2 service advisors and service techs that it happens on every merecedes-benz model no matter what, except the AMGs are not as long of a pause as the regulars are. They all said that it is for a saftey type thing becuase if you kick it and in putting yourself in danger, then at least you have a better leighway to stop the car....
I mean thats what they told me and i don't mind it...mine's a lease but i don't beat the heck out of it...

In 2.3L M111 this is done by directing more air to the cat for the first 45-50 seconds. This is the reason these cars are so noisy during the first minute after a cold start.

A moderator should consider putting (throttle lag) in the title of this thread, since that is what we're discussing.

well today i drove the car for about 5 minutes before getting on it and the pause was unnoticable. it probaly has somthing to do with the engine having to be warmed up

There is even a solenoid in the tranny in the W201 to make sure it does this. The W203 is also electronically controlled to hold gears higher for this operation.

Oh I know, that is why I never mentioned Hesitation. It is a delay in the shifting, actually called Upshift Delay! As for the throttle delay, these are Benz's and not designed for racing or off the line performance. The AMG's are for that. They are designed or at least intended to be Luxury cars and no luxury car needs to launch your head to the head rest upon launch, they are designed however to have some expception passing power and ability. Anywho, I got a 6 speed and I sense no delays when I hit the gas in my 2003.

Thread resurrection alert!
I've been searching this issue for a little wile now and this is the closest report that I can find to what I am experiencing.
What happens with me is there is a feeling of a miss on the 2-3 shift (At least I think that shift... the damn thing has 7 gears so its hard to keep track)
oh, BTW, 2007 C230 sport 2.5L auto
It will rev up and go to shift, and there is a period where the car stops accelerating, enough to toss your head foward a little bit. Its not violent or anything, just annoying.
It seems to get better when the car warms up, but it's a while after the engine is up to temp, so Im assuming the tranny has to get up to temp.
I stumbled upon the adaptive driving reset procedures where you turn the key on and floor the throttle for 5 seconds, so I'll give that a shot.
Has anyone else experienced what I am describing here? It's still under warranty, but I'm hoping the reset will cure it.
TIA!
