Hi DLM48
Just FYI, I own a MY 2006 C70 geartronic, I tried the gear lever with the key in the ignition and it was locked in P. Still locked in P at position 1, 2 & 3. Only able to move gear lever out of P with key turned to position 3 & my foot on the brake pedal, wouldn't move otherwise. On single touch window working I'm unsure whether they all have single touch. My front windows do, my rear don't, all 4 together do for going down but not coming up. Re-setting the front windows, I think holding the button down for about 10 seconds on opening,then up for about 10 seconds on closing. Open then close immediately. Hope this helps some.
Regards
Fred
