2000 Lexus LS (Mk3)

Top-spec UK LS 430 models feature electronically modulated height-adjustable pneumatic air suspension. Over time, the internal rubber air bladders suffer from dry rot and cracking caused by UK road salt and grit accumulation around the lower folds.

This eventually burns out the compressor motor and relay, leaving the vehicle uncomfortably low and triggering suspension warning messages.

Symptoms: One corner or the entire vehicle sitting visibly low after being parked for more than a few hours, Air compressor pump audibly running for prolonged periods behind the front bumper...
