If it ain't broke, don't fix it. I think the best thing to do is to find someone who could lend me a pair of actuators and see if the light still goes ON during climbing the ramp with those. Then I would know for sure the problem is really from the actuators.
Sounds broke to me. Just because the average person may not be able to feel it under normal driving, it still might make the difference between crashing and not crashing. The problem seems too consistent to be two actuators. You probably only need one for now. When the actuators were cheaper, I bought a new one and sent the other to be repaired, so I could use it for faultfinding at a future date. But that's just me.
Right it is broke, but only during climbing the ramp. Rest of the time the light is never goes ON, so that mean it's working. Of course I'd rather find out why it does light ON, but I have plenty other stuff to do on the car beside that. If anyone from France reading this is ready to lend me an actuator, you're most welcome
