Automatic Transmission Gear Indicator problems of the 2007 Audi A3

Car had occasional leaks had taken in for fix. Fixed but still had occasional leaks. Going around corners at low speed, occasionally car would jerk when the gas was applied like it has hitting the wrong gear. Had blinking prnds light while on the freeway. Car started rough next day with engine icon flashing. Took car for service, Audi tech found loose bolts in transmission pan causing fluid loss and small metal particles in pan. Road test found "hard shift in reverse and 1st". Replaced transmission. Concerned that the transmission failure could occur while driving and cause harm to myself or others.

I have an '07 Audi A3 2. 0tdi sportback wtih the dsg transmission. I don't know if I am qualified to fill up this form since my car is overseas (in the philippines). I just want to share my troubles with my Audi's dsg transmission. When I had about 18,000km in the clock, my dsg started to make some grinding noise and difficulty in shifting gears. I brought it to my garage to have my dsg inspected. The mechanics found out that the circlip holding the clutch pack of the dsg flew off. The fix was done by replacing the circlip of the clutch pack. The car then went fine. Fastforward to 2 nights ago (July 10th or about only 1,500km later), my dsg's instrument cluster started showing my the "flash of death" wherein the "prnd" lights kept on flashing accompanied by difficulty in changing gears! I am experiencing sudden lurching on first gear and the reverse gear totally doesnt engage anymore!!! I have my own diagnostic tool (vag-com fromross-tech) and it tells me this "pressure control valve 2 (n216): open or short to plus". I have done extensive research and my mechanics/garage and I have come to a conclusion that the problem is a failed mechatronics module on my Audi's dsg transmission.
