I had the same problem. I've had two problems with them and was able to fix through a lot of !Removed! around. 1. The first suggestion from the dealer was the alternator was wearing down and producing less votage to the sensor which was providing false readings. I didn't buy it, but it might be worth checking into. 2. My paint was just starting to chip off a few of my sensors. So I removed the flaky paint completely off the sensor. This did the trick. These things are so sensitive. The slightest micrometer of debris can set them off. So a little piece of flaking paint just bubbling on the sensor can trigger it. Anyone from a state with snow knows what I'm talking about. 3. Well now I have removed the paint, I now have grey dots on my bumper where the sensors are on a black car and it looks awful... but now there working. So next I have the bumpers repainted for a few hundred dollars, and everything looks great. Unfortunately, the new paint was thick enough to start triggering the senors again. I took it to the guy who painted the car and he removed the clear coat finish off the top of the sensors with some paint thinner and left a very thin layer of black paint. This did the trick. I have since talked to the dealer about and they are aware of this problem of repainting the sensors and will now refuses to do it. They only replace them now, for about $175 each installed. Hope this helps.

Sorry to hear and I do not have a happy answer. Here is what I found out. There are two sensors in the rear by each wheel that sense the heigth. These two sensors are relatively low quality and let moisture in. Eventually it fries the sensor out and you ride high all time. I escalated the process cause I washed the car a lot and the car wash I used had one of those high pressure underbody flushes. The dealer seems to be very aware of the problem when I talked with them over the phone. Considering it's solid state electronics, your just pretty screwed when it goes. The sensors look pretty easy to replace if the scews aren't rusted on, and you don't have to cut them off. Mine were so I had the dealer do it. The sensors in Milwaukee sold for about $350 each and $75 for installation each. I did both and the total job was around $800. I bit the bullet, spent the money and the car is now back to that creamy smooth ride. Wish I had better news. Good luck.

Hi All, I have a 2001 LS430 Ultra with 105K. Right now the air suspension compressor appears to be on constantly to all four wheels. This car is riding high and if I can't fix it maybe I'll just buy 22" wheels I have manually disconnected the height sensors on the rear with no luck (very easy, harness wire is right behind tire). I have manually adjusted the rear settings... No Luck. I have pulled the fuse on the compressor.. no luck, as I don't know where to bleed the air out. I believe my struts are fine as the car won't lower after many days in the garage, hence no air leakage. Any knowledge/ideas about this system or the location of the compressor or bleed valves would be greatly appreciated. My fear is if I don't get this shut off, somethings going to burn out, break or start leaking. The dealer already said they will start with the two rear height sensors ($420 each no labor). I explained, I believe it's the compressor switch as I have already tried running the car with the height sensors disconnected from the wire harness. They responded to bring it in and they will start trouble shooting at $120 hour. :cries: Yikes. Thanks for any input. Jack
