Losing rear air pressure

I just took my 2003 Winne Journey (Freightliner chassis) out of storage after a 2 yr hiatus. I've been just driving it locally to make sure everything still works. Today, the rear pressure gauge dropped to zero immediately, stayed that way a minute or 2, then came back up to full pressure just as quickly as it dropped. I couldn't hear anything from inside, not sure I'd have heard it if I were outside due to the engine noise. Is it possibly a sensor issue? Even sitting still, just idling, it did it once, still couldn't hear any air escaping. I'd have to believe you could if it was being released that fast. Any suggestions?

    I have an 03 Journey and same thing happened to me with front air. It is the vdc as mentioned. Just note to yourself that it will not cause you to breakdown or anything. Just totally annoying.

    Dave, I highly suspect you have a problem with the VDC (vehicle data computer). The FL VDC/VDU in those years were notorious for having some cold solder joints that cause the exact problem you are having. I had same issue with my previous coach, a 2002 Journey. The fix is pretty simple if you are good with a soldering iron or pencil.

    A new VDC is about $400 from FL. If you want to try and remove the VDU and do the repair yourself, send me a PM with your email address and I will send an article with pics and instructions on the repair.
