I beg to differ, as I did exactly that. With my P85+ I experienced a constant pull to the right on the steering wheel, that several attempts by the SeC didn't fix. Being fed up with this and afraid of the extra tyre wear, I took the car to my tyre specialist for re-alignment, on my dime. They fixed it in less than 45 minutes. One happy camper and never looked back....The OP wouldn't take warranty repairs to another repair shop and pay out of pocket...
This was early 2014, probably (hopefully) the SeC got better at this nowadays.
