You need to type something in legible English. What are you asking and what are you trying to say?

Otherwise the answer you'll get is "cool story bro! "

Symptoms are no codes car shudders when trying to pick up speed especially at off a light acceleration and the stability light kicks on

Is this something you can reliably reproduce on demand or is it intermittent? Is it conditional, like only occurring after the car is warmed up or only when it's cold? Does it happen at any speed/gear or only when starting from a stop? Does it happen in sport mode?

I get this too. When I go to work the first time coming up to speed on the highway (happens maybe 1 in 5 times) I get a slight shudder. Don't notice it anywhere else or after the car is warmed up.

A bit concerning but wasn't able to reproduce it when I told the shop about it. But it is inline w TC symptoms. For some reason I notice it a lot more on my summer staggered setup than my winter square one.

Great questions, I'm following this post. My e90 xi shudders always at 1.8k-2.3k rpm in any gear unless I'm in sport mode almost always. Doesn't matter if it's cold or hot. If I hit the gas to go above those rpms shudder goes away. Car is fine WOT

EDIT: I know this is an f30 pst but I figured it may be the same reason

I ran it through google translate and got:

"I think it's on its way out"

Good luck figuring out what's going on, OP.

Have you had wheels off recently...could one of your speed sensors gone bad from a major pothole hit?

No codes after seeing a stability light? You mean no CEL? Did you search for codes, even temporary codes?
