Attaches to E61 at chassis level · Suspension · carried by 8 variants across 1 chassis
Overview
Rear self-levelling air suspension leak (Touring) is a common fault recorded against E61 at chassis level, typically from 120–220k km. It shows up as the rear of the car sitting low after standing overnight, a suspension warning, and a compressor that runs for longer than it should. Where it's documented, the repair runs €500–€1,100 (air springs or compressor fitted at a specialist, costs dated 2026-07), and it can be checked before you buy. 8 variants across 1 chassis in this database inherit it.
What happens
Symptom. The rear of the car sitting low after standing overnight, a suspension warning, and a compressor that runs for longer than it should.
Cause. The rear air springs perish and leak, and the compressor wears from working to compensate. The E61 carries this system as standard, so every one of them eventually meets it.
How to check it
Static checks
Park it level overnight and look at the rear ride height in the morning, then listen for a compressor that runs long after start-up.
Engine off, ideally on a lift.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
