Rear Lock still flashing -> solved ✅

[TheComedian]

Lot's of good info in the 80 series forum on rebuilding locker actuators. One issue that crops up is the magnets with the electric motor become unglued from the housing and simply regluing the magnets to the housing corrects the problem. I suggest you clean it and try rebuilding it, nothing much to loose at this point.

I did a rebuild with a bowdencable.

The flashing light of the locker comes from the actuator. So first I would try to just disconnect him to see if the loght goes away. If it goes away it’s the actuator itself. If not you have something electrical elsewhere.
The sensor is (as I see) only to for the ABS. But maybe they work also together. In case you can remove the sensor and press him (the oil level in the rear diff is lower than the sensor).

If your actuator is in a good condition you try to open him to see if maybe something is stuck or just dirty.

Thank you! This gave me a bout of confident in addressing it.

It appeared to just need a dustoff near the actuator and has gone away. Turbulent weather is probably the culprit.
