E92 M3 DCT not automatically downshifting in D?

Hey all,



I've been having some troubles for a while with sporadic downshift issues when I'm driving in automatic. This usually happens when I commute to work on the highway.



Current scenario:

• I'm driving down the highway doing 60mph, D (which chose 7th gear), S-4


• Need to pass a car


• Press down on the accelerator (note: not all the way down till it "clicks" and shift to 3rd)


• Car stays in gear and surges slowly forward

Expected scenario:

• I'm driving down the highway doing 60mph, D (which chose 7th gear), S-4


• Need to pass a car


• Press down on the accelerator (note: not all the way down till it "clicks" and shift to 3rd)


• Car downshifts to the appropriate gear (3 or 4) and takes off faster

Here are some videos I took for the shop

It has always downshifted on acceleration in the past, and this shifting behavior sporadically changed into now no downshifting at all. Because the downshifting didn't work, I almost got into an accident yesterday because the car did not accelerate quickly enough out of dangerous situation -- it refused to downshift upon pushing the accelerator pedal down.



The shop thought it might've been the steering alignment sensor, but resetting this did nothing.



Any thoughts?



Cheers,
