Hey guys. I could really use some help in figuring out what is wrong with my 2003 cayenne S. I have the dreaded red air suspension warning on right now.

ive checked the 40a fuse and the two related fuses on the passenger side dash, replaced the compressor relay and the fault still exists.

i ran durametric and got a terminal 30 fault. See attached pic.

battery is 12 months old and still showing 13.6 volts with the car on and 12.9 car not running at the posts.

under the dash i placed a jumper from the big red wire to terminal 30 to ensure constant power. Cleared fault and it went away. UNTIL about 10 mins of driving around town the red air suspension warning comes back. After a few mins it’ll dissappear and i can operate the system again. Up/down.

if i remove the jumper. Voltage at terminal 30 based on live data on durametric shows 5v.

what should i be doing to chase down this issue.

i also checked the three splices in the driver side floor and those are all solid and nothing has
