[Bluesummer]

It was a perfect afternoon and I was on my way to pick up a copy of FF XIII. Just as I pulled into bestbuy's parking lot, I noticed an unusual jerky gear change from the DCT (mind you the car is flashed according to SIB280708 last June). Didn't really mind it and kept driving toward a small intersection with stop signs and an incline. I fully stopped the car and gave it a little gas when it was my term to move but I soon notice the hill assist was completely gone and I had to give a little bit more gas than I usually do to prevent rolling further back or possibly stall. Got out of the intersection, I was scratching on my head and the next thing i found out is my iDrive telling me DSC malfunction, Engine malfunction and of course a limp mode (see pics below)

could this be the idle valve cause that's the only known issue that has not happened on my car...

All the above incidents happened in a parking lot, hence, really slow speed.
