    Is it possible to read which corner it is with a diagnostic tool? I thought it would be worth asking here before i drive it over to the mechanic.

    I know that my front left side has had a broken gear but i have repaired it and light is still on. Wondering if more corners are broken or if my repair wasn´t good enough.

    Need an SD2 to get details. Also note that even though the light goes out when you fix a problem, the error is stored until cleared. There may be many old errors stored which will be misleading, so best to clear all suspension codes, then drive and read again.

    Are you sure? I’ve heard it does not need to be deleted if the issues are solved from 2 different Ferrari mechanics.

    You are correct, you don’t have to delete the code to get the light to go out, but the code is stored in the ECU until cleared, at least that was my experience. I had all 4 actuators rebuilt to get rid of the light, and then the light on the dash came on again. My mechanic scanned with his SD2 and it said all 4 actuators were locked. Cleared all the codes, went for a drive and it came back showing only one actuator failed. Turned out to be an electrical issue inside the actuator this time.
