Can i test xenon lights sensor on rear axle or replace it. Xenon lights very low (about 15 feet) on dip.

Is it in good mechanical condition and fitted correctly?

To @Sirikishna - Hi.. I have may be the same Problem with front lights level module, situated on the right side of the back suspension. My front lights do not lift up and glow very low, about 5 Meters in front of the Car. My module was very rusty. The ball joints of the module not move at all. I remove the module, clean and lubricate very well ball joints and gently start moving it. After few Minutes, the ball joints start to move very easy. The box where the electric cable are attached looks perfect and I think that there is no Problem inside. After install the module back my front lights lift up and glow normaly.

 

I think that this module need to be cleaned and lubricated, without removing it, two times a Year, in the Spring and Autumn for example, when change Summer/Winter tires. I think this will take 2-3 Minutes and prevent Problems in feature.

 

Important: There is another front lights level module, situated on the front suspension, behind front left tire. I have no time to check it but will do soon. Mey be the situation is the same - rusty. Check it too and do the Problem prevention like clean and lubricate very well.

Thankyou very much.  Will give that a try and let you know wha happens.
