2013 x5 35 i M sport , 5K milage ,got following error
-parking brake malfunction
and also followings in the same time
-Braking/chassis stabilization malfunction
-FTM system error
-parking brake malfunction

both above happened few times and restarting the engine clear it.
Dealer scan the car and said left speed sensor caused the issue .the said corroded pins on left wheel speed sensor .They ordered new one and swapped it with right one to see is it the root cause or some thing else .I will go to dealer to put the new one next week ,in mean time I got couple of more malfunction messages so they will find if the sensor is faulty or some thing else.

I do not understand why 6 months old car has corroded pins ,may be water leak inside it during car wash ? I checked the wiring harness behind front wheels that go to the black box that connect to the sensors ,the wiring harness are there without any shield (surprise to see it from german engineer car).they could simply tape the wiring harness with waterproof tape and make the plastic box waterproof .

Any way , I will let you know what will happen next week when I go to dealer to scan the car and replace faulty speed sensor .
