Thanks. Yes, it is on air suspension. Tyres are all OK. Unfortunately no warranty. Only had it a week and a half. Have been in touch with the trader and they are going to have it back Monday to investigate. Hope it's only the sensor.
I recently bought a 2007 ls460 sel with 61000 miles on and noticed this morning that the rear passenger side is sitting about an inch lower than the driver side. Any ideas. Thanks.
