Auto Levelling Sensor in rear suspension????
 

does the 3 even have one??

i was doing some research and came across this. i would go check on my own car, but seems impossible since its in the shop still...(slow bastards)... anyways.. i know high end luxury cars have this like bmw's, but i really didnt expect it to be on the 3...

nope, the 3 does not have one, and i dont see the point of it on our cars.
it would add ALOT of wieght, and you get the same effect from a prokit

My 1990 Mazda MPV 4x4 has it :)
