Reduced Power...Again.

took the car out, 2011 e90 m3 on the canyons, day went by without a hitch... till i filled up (.9 miles from home) and started the car. had the DSC, ABS, Increased Emissions, lights came on. m3gasm says its actuator.

Odd thing is when i drove home is that it automatically shifts up and down even when in Manual Mode. i have no control of the transmission. It has trouble idling, accelerating and decelerating.

i have yet to read the codes, but i think its TB's, has anyone experienced the part having no control on the transmission?

Sucks... But read codes first, then post the codes.
No one can help without them.

About a month ago you tried to flash the dct and failed.

Did you keep trying?
What happened, did you succeed?

Looks like your car has plenty of codes thrown the last few month. Any solutions for those previous errors?
The tb can cause all kind of codes it seems and so can a battery / alternator issue.

And no, the tb do not interfere with the dct directly.

But who knows what the car is doing when they go bad, perhaps wants to stay in a certain rpm range?

i didn't flash the car at all, just try to do a cold run of WinKFP (winkfp was not plugged in to the car)

changed the spark plugs of the car, it solved the previous reduced power Problems.
i totally that the alternator might be bad, however, car seems to be keeping 12V, when off and ~14V when running. i also thought that car was shifting by itself to keep within an RPM target.

update: cleared the codes and left the car for like 3 days. started the car and took it for a spin around the block 3x when I arrive at the stop sign, car idled really rough, bouncing from 450-750. came back home, and sure enough, it threw a bunch of codes and went limp mode again. its not the old codes this time. Now it is 279D and 2B0D & 2B57

another update:
cleared codes and adaptations, took the car for a spin around the block, same thing. started to idle badly and went in to limp mode and threw these codes this time

another update:
removed the actuators, found that the swing arm takes a lot of force to open
proceed with opening both throttle actuators found that both actuators have been previously rebuilt. they were rebuilt with the brass and delrin or Teflon gears. the brass gear was binding to the shaft of the housing.

FIXED

It was the Throttle Actuator, I got Away with just rebuilding mine:happyanim:

Glad it worked out.
