Part of the reason I say you need an air system diagram , linked to your serial number , is the over the years Freightliner has changed the air suspension system , my 99 chassis has 3 ride height control valves ; 2 front , 1 rear ; other members report , 1 front and 2 rear . I believe one year had 4 ride height valves.
But as I mentioned , my chassis air suspension , draws all it's pressure from the front tank, so the front tank gauge is the one that moves while I'm cruising .
As CaptBill has mentioned , I typed in the Freightliner phone number wrong.
1-800-385-4357 is the correct number
EDIT: A second thought , I always have them .
Your VDC was replaced , and movement in the front tank gauge is normal due to air suspension using air . ( exhaust brake , air horn )
Our electronic gauges respond to an individual signal , from the VDC, that signal could be incorrect , for the front and rear gauges , IF the front & rear air system lines; that provide the tank pressure to the sensors ; were swapped when the VDC was installed .
