2008 f8 lxr reverse actuator issue.

[mgsimon]

When try to use reverse I have to hit the button a couple time, and then the ccu error comes up.
It does go into reverse and come out, but to clear the ccu error i have shut off and restart.
Any help would be appreciated.
Thanks

Funny just had this exact same issue on the wifes 2014 XF 1100. ECU flashing when you tried to put it into reverse. It's the gearing for the reverse gets stripped. Known issue. Dealer put a new gear/sprocket on and issue fixed.

Was it the unit that engages the reverse or in the diamond drive.
Thanks

Its the unit/gear that engages the reverse not the diamond drive.

Two different drive trains.
Mgsimon, the early DD sleds did have some failures on the CCU. But, first check belt deflection. Sometimes the servo for reverse does hang up with a tight belt. You may get it to shift and still see the error code.
If your belt isn't too tight, it may be the CCU itself.

I didn't want to mess with it as we were putting new pistons and rings in the sons sled so I just took it in. $130.00
