Hi guys, the gear indicator on my 2006 F430 (F1) started blinking after I would drive the car for about 1/2 hour. This was happening consistently on every drive I took. There were no issues with shifting though. My mechanic looked at this and found no fault codes. He sorted this out by doing an actuator calibration and then running the shifter through a self-learn sequence. Issue was totally fixed! So if this happens to you, check into this solution. Hope that helps. Cheers.
