Shudder on acceleration.
 

Hi everyone, when accelerating at a medium speed I experience a slight shudder when depressing the throttle, has anyone else experienced this? On a 2012 C63

It's the sound barrier,

Do you mean a hesitation?

Stock ?

Could be O2 sensors

:rolf:....he didn't say at WOT with headers and catless mids

Opps your right my bad

That comment is so win :rolf:

:rolf::rolf::rolf::rolf::rolf::rolf:

Issue with MCT?

Yes the car is stock! I phoned the workshop and they just told me its how the new MCT is..

Not true... I have zero issues in acceleration. They are making excuses because they don't know what it is.

I thought it was from entering "warp speed"?:D

Yeah that's what I thought, that's why I'm asking here, I think I'll try another workshop and take it in?!

Take it to the dealer, u got warranty.

I just took delivery of my 12 a week ago. I'm experiencing the same thing, especially on light acceleration between 1500-2500 rpms. It's really beginning to tick me off, and I can't stand the thought of hearing the stealer tell me "it's normal". Please let me know if you learn anything. It almost feels like a MAF sensor or something.

Off Topic : I'm sorry dude, but your wheels are really bad. It's so ghetto imo

hmm..ADV-1 wheels ghetto...interesting

I don't care about the brand, I'm not expert in wheels, even if you paid $1M for it, they just look gross. Not for a C63. Maybe for a GM.

Grammer either, obviously.

nor speeeeling :)

i like them!

They aren't bad at all! There have been way worse on this forum! I like the 10 spoke trakfunction more but these are great!

I don't know what you mean by shudder... I haven't felt anything. The only things with my 2012 is that when Im stopped and put it into S or S+ the car jerks, and when Im driving in S+ the car will keep the revs quite high after I have stopped accelerating. I usually just grab the paddle and it shifts up right away. If I don't grab the paddle it take about 5 or 6 seconds for the car to 'decide' to shift.

I'm foreign.

Thanks, I almost got the 10 spokes actually. In the end I thought the spokes were a bit thin for the car, but it was a tough choice. I thought the 8's looked a bit more aggressive for the car.
Anyway, it's not so much a shudder, but more of a slight stumble/hesiation maybe. I use M mode most of the time anyway and it's much less noticeable.
Anybody have a tune on a P31 '12 that saw improvement on this?

thanks,

Definitely not.. he stated his car is stock... so no flux capacitor.. :rolf:

i have a 2012 and have no such shudder. Mind you in our city "medium speed" is like 35 kmh. lmao
