Historical MOT pass rates and DVLA records for 2004 model year cars.
- Biodegradable wiring harness insulationSerious
Mercedes used a soy-based wiring insulation that degrades over time, exposing bare wires and causing short circuits, random warning lights and potential fire risk. Engine bay harnesses are worst affected.
- Airmatic suspension collapseSerious
The air springs and compressor degrade with age. Cars sag overnight, ride poorly and the compressor eventually burns out if leaks are ignored.
- SBC brake system failureSerious
The Sensotronic Brake Control unit can reach its cycle limit or fail, bringing brake warnings and a hard pedal. Replacement units are expensive and the system is complex.
