    Two months ago on Tail of the Dragon my F12 went into limp mode and had a multi system failure.

    Got it towed to Ferrari Atlanta and they told me the rear right ABS sensor (wheel speed sensor) broke, they replaced it and the vehicle has been running fine.

    Until ~2000 miles later, two days ago, car went into limp mode again with the same failures.

    This time I had the help with a local mechanic/good friend that works on exotic cars. So we scanned the car and found out the rear left abs sensor has broken.

    We cleared the codes and started troubleshooting, found out that whenever the car’s rear left wheel goes over a bump the warnings will reappear. I was able to go 100mph+ if the road is smooth, but as soon as I hit a bump (regardless of vehicle speed, it could be 30 mph) the car would go into limp mode. We’ve decided to not tow the car all the way to the dealer (which is over 2 hours away) and DIY fix this issue, new ABS sensor and clips have been ordered from Scuderia Car Parts. More updates coming soon.
