    Volvo 780 front air bags deflating

    I drive a Volvo 780 which has air bags on the steer axle. After the truck has been shut off for a few hours BOTH bags completely deflate. I can not see (soapy water and spray bottle) nor here where the air is leaking from. They both inflate quickly when I start the truck and the compressor has no problem keeping them inflated but I would like to get this fixed IMMEDIATELY before I get placed oos.

    Anybody have any suggestions to help me locate the leak?

    Follow the lines and spray water on each connection. Also check the front suspension air ride leveling valve.

    Not sure what ECAS is but it does have a leveling valve on the front, which is less than a month old.

    sometimes levelling valve looses air and no sssss sound. so the only way is to get bottle with soap water and find problem from underneath

    the bags going flat after a few HOURS is not an OOS violation. the only oos violation is if there was an audable leak bad enough that the compressor couldn't keep up
