Lexus LS Air Suspension Failure

That sounds frustrating! I had similar symptoms with my LS – although I don't remember the exact build year. I remember my car was also leaning pretty bad, and the error messages were driving me crazy. Did you check the cable and plug connections to the air suspension compressor? That was the culprit in my case; a defective cable connection can cause all sorts of weirdness with the ride height, air struts, the whole suspension system.

Interesting! Where exactly is that cable connection located? I'm reasonably handy, so I might be able to check it myself before taking it in. Is it easy to spot, or is it buried deep within the suspension components?

Unfortunately, I'm not entirely sure of the exact location myself, as I had a workshop check it out. However, given that your error memory also stored an error and the symptoms are the same, I'd strongly suggest taking it to a qualified technician. It's quite possible that the cable/plug is indeed defective. I know it's a pain and potentially costly, but messing with the suspension system yourself could lead to other issues. Better safe than sorry!

Thanks for the advice! I took it to my local mechanic, and you were spot on. Turns out it was indeed a defective cable connection on the compressor, costing me only 95€. All the symptoms are gone now. Appreciate the insight!
