Hi guys, couldnt get the air suspension to work all day until the end of the day it levelled out to normal lever then I could even get it up to maximim, although it worked in the end Im worried what could be wrong, any ideas? Today again it wont go up...

A lot more info is needed. Mileage, what has changed lately. Have you had your tires changed. Anything or any info would help.
