Auto levelling headlights

[Alex of Smeg]

I have a 2011 type S, the stupid auto levelling headlights are a nuisance especially on these dark nights. If I'm parked up stationary then the lights come up high and if I jump on and off the tow bar they adjust accordingly. But when I'm driving they just go to their fully dipped no matter what so I can only see about 4m down the road. Anyone know what to try? Testing resistance on the sensors or something? If not can I unplug them when I get them in a good position? Which plug would it be? TIA

try the height sensor on the back axle if its broken it wont level and lights will be at their bottom
