Did you happen to confirm it was the sensor?
And exactly which?
My car battery went dead after I didn't use it for 9 days. After I recharged battery, air suspension jacked to maximum height and wouldn't come down---car bounced you with every bump in the road, even the slightest rise.
Weirder, the next morning, about 90 minutes after I used the car, a loud bang shook the house. Looked outside and saw left side of vehicle now sagging as low as it could go in the back. Must have blown my air shock (replaced the right one a few months ago, but that left one at least 80,000 miles old).
Am trying to sleuth this best I can. Suspecting control module--and yes, did find some water/dampness in spare tire well. Currently drying it out.
If you did find specific reason and wouldn't mind sharing, would love to hear what you found out with your situation. Happy Motoring, in any event!
