Hello everyone,

i have a 2014 mercedes cls550, during the weekend i had some service done to my vehicle. lifted the front with the jacks and was probably jacked for almost half a day, when i lowered it down the airbags were deflated and compressor wont kick in to raise the vehicle. i had my compressor replaced about 1 ish year ago by local dealer and it worked fine until now. hooked up a computer and attempted to manually lift it but unsuccessful. any ideas what could it be?
