Historical MOT pass rates and DVLA records for 2018 model year cars.
- Airmatic Suspension FailureSerious
The AIRMATIC semi-active air suspension system features rubber air spring bellows that perish and leak over time, valve blocks that seize, and an electric air compressor that burns out from running continuously to compensate for pressure loss. Replacing struts and compressors carries substantial parts costs.
- NOX Sensor FailureModerate
Diesel variants (OM642 3.0-litre V6 in S 350 d and OM656 2.9-litre straight-six in facelift models) suffer widespread failure of the upstream and downstream nitrogen oxide (NOx) exhaust sensors. Moisture ingress and thermal shock damage internal sensor ceramics, causing engine warnings and non-start countdowns.
- Front Suspension Ball Joint and Control Arm WearModerate
Weighing over two tonnes, the W222 exerts tremendous load on its complex multi-link front suspension. Lower control arm compliance bushes, track control ball joints, and anti-roll bar drop links wear rapidly on UK roads, resulting in knocking over speed bumps and MOT failure.
