2012 Mercedes-Benz E 2.1L Diesel · FN12 LPZ

The most recent DVSA MOT test on 21 April 2026 resulted in a pass, with the examiner recording an advisory for slight damage, cracking or perishing to the nearside front tyre, an advisory for the offside rear service brake binding but not excessively, and a minor for windscreen damage not adversely affecting the driver's view. Looking back across the available history, the vehicle has now passed four consecutive tests, which on the surface suggests a stable maintenance trend. However, the underlying picture is one of persistent and recurring advisories centred on the front wheel bearings, front brake pipework and front brake hose ferrules, all of which have been flagged repeatedly since 2021, alongside a prior major failure for both rear coil springs fracturing and a further major for a corroded front brake pipe in 2023. The recent emergence of an offside rear brake binding advisory is a notable development that warrants close attention, as binding calipers or seized sliding mechanisms tend to deteriorate progressively and can lead to uneven pad wear, disc overheating and reduced braking efficiency if left unresolved. The recorded mileage of 132,431 miles over approximately 14 years equates to an annual average of around 9,459 miles, which is broadly typical for a vehicle of this age and not indicative of unusually low or high usage. There are no obvious large gaps between test dates, suggesting the car has been in regular use rather than left standing for extended periods, which is generally beneficial for the preservation of seals, brake components and the 12V battery. That said, at this mileage many mechanical components on a 2012 Mercedes-Benz E-Class will be approaching or past their typical service life, including suspension bushes, coil springs, anti-roll bar links, brake discs and pads, and the dual mass flywheel if fitted with a manual gearbox, and these items will not necessarily have been flagged on the MOT. A prospective buyer should focus particular attention on the recurring front wheel bearing advisories, which have now appeared across four consecutive tests. On a road test, listen for a humming, droning or growling noise that increases with speed and may change when cornering, as this is characteristic of worn wheel bearings progressing from slight play to a more pronounced failure state. The front brake pipe and hose ferrule corrosion advisories also point to a systemic deterioration of the braking hydraulic system, which is common on older Mercedes vehicles exposed to winter road salt; the near-side pipe has already failed once as a major defect, and a careful inspection underneath should be carried out for any further corrosion, weeping joints or perished rubber sections, with a test drive confirming a firm, responsive brake pedal without sponginess or pulling to one side. The latest advisory for offside rear brake binding should be specifically investigated by checking for uneven pad wear, a hot wheel after driving, or a dragging sensation, and the nearside front tyre perishing should prompt replacement regardless of tread depth given its age-related degradation. Beyond the recorded defects, this 14-year-old E-Class warrants a thorough age-appropriate inspection even though the annual mileage is unremarkable. Tyres should be examined for sidewall cracking, perishing and manufacturing date codes, as rubber deteriorates with calendar age regardless of tread wear, and a full set replacement is likely due. The 12V battery, which typically lasts five to seven years, will almost certainly be due for renewal, and a voltage or load test is advisable. Brake discs, even with adequate material, may exhibit corrosion ridges or lipping from age, and the fluid should be considered overdue for a calendar-based change since brake fluid is hygroscopic and degrades regardless of mileage. The underside should be examined for structural corrosion, exhaust integrity, fluid leaks from the engine, transmission and differential, and the condition of all suspension components including bushes, drop links, shock absorbers and springs, with a particular listen on the test drive for any clonks, knocks or knocking over uneven surfaces that would suggest worn suspension joints typical of a vehicle at this mileage.
