Historical MOT pass rates and DVLA records for 2004 model year cars.
- Rear axle and floor corrosionSerious
Older W168s can corrode around the rear axle mounts and floor seams badly.
- CVT / Sequentronic gearbox failureSerious
The CVT and semi-automatic Sequentronic gearboxes can suffer from wear to the variator, clutch packs and mechatronic units. Repairs are often uneconomical on higher-mileage cars.
- Water ingress and electrical faultsModerate
Blocked sunroof drains and degraded door seals allow water into the cabin, which can corrode underfloor electronics and wiring connectors, causing random warning lights and intermittent faults.
