04 L322 Air Suspension Inactive after sitting

Hi Guys,

I have a 2004 Range Rover, I've read a bunch of posts yet I just can't figure out what the issue with my suspension is. My car was vandalized while it wasn't insured and it sat with no battery connected for a good 8 months. I got it painted and realized that the suspension was completely decompressed. I tried doing the "turning steering wheel lock to lock" method but it didn't fix the issue. The instrument panel where i can raise or lower the SUV has no power at all and I keep getting an "air suspension inactive" light. I checked the 15 amp fuse in the glove compartment and it was good I put in a new one just incase. Any idea how I can get it back up and get the system power again? I did notice my tires have low air pressure too I don't know if that would make a difference but I have to get the rusted valve caps off and fill them up still. I hope you guys can help me, I've already had to pay so much just to get the vandalism taken care of.

You will need to have the trouble codes / fault memory cleared from the air suspension control module and then the air compressor should kick back on and inflate your air springs. When you have a hard fault stored it will shut down the system. You will need a scan tool that can communicate with the air suspension control module to do this.
Agree with the post above. You need a tool to read the faults first and then clear. On a side note a rodent could have chewed electrical wire on the suspension height wire or valve block while the vehicle sat for 8 months. I personally experienced that from purchasing one from auction where it sat for a while.

You can get the tool from Amazon for a 2003-2005 Range Rover for somewhere around $25. Search for "bmw scanner version 1.4.0". I had to solder in a jumper wire to make it work, but many references to the work around on the web.
