2010 Mercedes-Benz E 2.1L Diesel · N60 ODA

Mechanical concerns regarding the braking system and engine management systems emerged prominently in the 2025 testing cycle, though the most recent test on 13 August 2026 shows a pass with new advisories. While the vehicle has maintained a relatively consistent pass record since 2020, the 2025 failure highlighted significant issues including an inoperative engine MIL and a parking brake that failed to meet efficiency requirements on the nearside. The current status shows a shift from those major functional failures toward emerging wear-related advisories, specifically an oil leak and slight play in the nearside front wheel bearing, alongside a loose rear exhaust heat shield. The vehicle has covered 117,572 miles over its 16-year lifespan, representing an average annual accumulation of approximately 7,348 miles. This usage pattern is typical for a vehicle of this age and suggests a moderate level of operation rather than heavy commercial use or prolonged periods of inactivity. From a mechanical standpoint, this mileage level means that while the drivetrain may not have faced extreme high-stress cycles, components such as suspension bushes, wheel bearings, and various seals are reaching a stage of life where wear and gradual degradation, such as the currently noted oil leak, become more frequent. A physical inspection and test drive should prioritise the newly flagged nearside front wheel bearing and the reported oil leak. During the test drive, listen for a low-frequency humming or grinding noise that increases in pitch with vehicle speed, which would indicate the bearing play is progressing. Regarding the oil leak, the inspector should check the underside of the engine and transmission for the source of the seepage to determine if it is a minor gasket weep or a more significant leak from a seal or oil pan. The loose rear exhaust heat shield should also be checked for rattling or vibration, particularly during cold starts or under acceleration. The history of parking brake inefficiency and the inoperative engine MIL in 2025 necessitates a thorough verification that these systems are now fully functional. Ensure the parking brake holds the vehicle firmly on an incline and that the dashboard warning lights operate correctly through a full ignition cycle. Given the previous advisory for offside front anti-roll bar linkage play in 2020 and the current wheel bearing advisory, the steering and suspension should be scrutinised for any knocks, knocks, or pulling to one side when navigating uneven road surfaces or during low-speed manoeuvres.
