2010 Mercedes-Benz E 3.0L Diesel · B19 DAW

The most recent MOT, dated 16 December 2025, recorded a pass for the vehicle’s mechanical safety items but issued a failure for the off‑side headlamp being missing, which means the car did not receive a valid MOT certificate until that defect is rectified. Apart from the lighting fault, the test highlighted the same front‑suspension and shock‑absorber concerns that have been recurring for the past three years, together with advisory notes on brake‑disc condition. Overall the maintenance trend is neither improving nor deteriorating dramatically; the car has been kept road‑worthy but is showing the expected wear on age‑related components and a lack of timely corrective action on the identified faults. At 207,022 mi the 2010 Mercedes‑Benz E averages just under 13 000 mi per annum, well above the typical UK private‑car usage of 8‑10 000 mi per year. This higher annual mileage accelerates wear on consumables such as tyres, brakes, suspension bushings and engine oil, and it also suggests the vehicle has spent a considerable amount of time under load rather than in long periods of storage. There are no obvious mileage gaps in the recorded history, indicating continuous use rather than long idle periods, which means corrosion from standing is less likely but the cumulative mileage will have contributed to the progressive degradation observed in the MOT advisories. When you inspect the car, give particular attention to the front shock absorbers; the repeated “light misting of oil” advisory points to seal wear that can lead to loss of damping, resulting in a soft or “mushy” feel over bumps and possible clunking noises when the suspension compresses. Examine the suspension arm ball joints, pins and bushes on both sides for any play by pushing the wheel inward and outward at the 12 o’clock and 6 o’clock positions – excessive movement will be felt as a knocking or wandering sensation during cornering. The brake discs on both axles have been flagged as worn, pitted or scored; measure the remaining thickness (typically a minimum of 1.5 mm is required) and listen for a high‑pitched squeal or shudder under hard braking, which would indicate the need for resurfacing or replacement soon. Verify that the missing off‑side headlamp and rear stop lamp are fitted and correctly wired, and check for the oil‑leak advisory by looking around the valve cover, oil filter housing and under the engine for any fresh oil stains that could indicate a developing seal failure. Beyond the specific MOT items, a vehicle of this age and mileage should be examined for tyre sidewall cracking or dry‑rot, especially if the tyres have not been replaced recently, as age can degrade rubber even on low‑wear tread. Test the 12 V battery voltage under load and ensure the terminals are clean, because a 16‑year‑old battery is likely approaching the end of its service life. Inspect all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – and consider a full fluid change if the service stamps are missing or the last change dates back several years, as fluids degrade with time regardless of mileage. Finally, review the service book for evidence of regular oil changes, timing‑chain or belt service, and any major component replacements such as the timing chain tensioner or water pump, which will give you confidence that the drivetrain has been maintained in line with the manufacturer’s recommendations.
