135i Cobb N54 Auto Problems
The car sometimes shifts wierd especially in ds manual mode using paddles. i changed the gear and it sometimes slip or doesnt change today i even had a light come on in the center dash a circle with ridges and exclamation point in the middle. This occured only once i installed and ran cobb stage 1 sport mode, almost as if the n54 steptronic cant handle the added power whats going on am i gonna ruin my transmission i cant find one other thread with 6at auto problems in the 135i. when i was stock i had zero issues

haha i wish bro its actually a transmission failsafe light. its a circle with ridges and the light came on when i set crusie at 67 mph i noticed the rpm kinda stuck at 2800rpm not shifting to 6th moments later that light appeared. i am well aware of dtc and holding it 3 second to fully turn traction off and see that light that didnt turn on. im worried as my car is bone stock cobb only has me thinking the 6at not as strong as we all like to think atleast not mine cuz under full boost changing gears it sometimes acts wierd..
o and i jad a 540i for the last 5 years torque was all i knew 325ft lbs ! |
