2006 Monaco Dynasty front air tank pressure

[bandit411]

Front air tank gauge reads 0 rear tank reads 130 low air alarm sounding. But front tank holding air. Any solutions would be helpful.

Bandit, both sides of the front tank have air? Ours, while older has a split tank up front, one side is the wet tank and the other front air supply (it looks like one tank). There is a check valve between them.

There is also a module that controls the air gauges that goes bad.I remember reading about it on several forum threads.

I haven’t checked that I checked the pressure relief  valve

Do you remember where it is located in the coach.

The unit is called VDU Module 

It was used on a number of Freightliner  Chassis. Not common on the Monaco Chassis There should be a Red and Green 1/4 " lines connected directly to the dash gauges.

      Have you checked for an Air leak at the dash Red and Green Gauges. 

       Does the low air buzzer, continue to buzz? It could be a defective Gauge or something is crimping the air supply line between the frame and coach floor!

       Monaco Owner Manuals cover a number of the internal connection information!

When was the last time you purged the front air tank?

[bandit411]

Thanks for all the ideas I have checked for leaks replaced the drive motors in the gauge and tried a few RV scrap yards but I can’t seem to find the vdu module so that I could replace it. If anyone knows where I might find one please send me the address. Thanks

Call Freightliner and give them your VIN . . . They'll tell you where it is and what the part # is.

Monaco has a Roadmaster chassis not a Freightliner, sorry.

 Freightliner motorhome chassis built the durable B-Series Roadmaster chassis in 2006.

There is no information on the 03 to the 06 model years on the Monaco website.
