you have most probably PIS setting to be adjusted or air in your F1 system. wrong PIS means your F1 sensor reads your clutch to be either too near or away from flywheel and does not allow you to engage reverse. IMO since your car has not been driven but probably been left sleeping in the garage , Scuderia has problems with actuator valves, if not driven air is slowly sucked into system creating air bubbles that do not permit to gain enough pressure on some gears engagements. (exemple your reverse gear) I had the same problems with 6th to 5th gear. System purged and now perfect. You need to drive your car more or you will face this problem again.
My scud is changing gears slowly exactly like a regular F430 do. Do you think maybe I have air in the system? Car was seated for months... Sent from my iPhone using FerrariChat.com mobile app
Hi - Sounds like I've had same problem w my f430, I tried many service centers to figure out the problem. I end up found that shifting robot was the issue.
