2004 Mercedes-Benz CLK 5.4L Petrol · DU04 MYC

The most recent MOT on 11 July 2026 recorded a failure for two major items – the nearside windscreen wiper does not clear the glass effectively and the nearside front tyre is fouling the arch liner. This contrasts with the three preceding annual tests in 2023, 2024 and 2025, all of which passed without recorded defects. The pattern suggests that the vehicle’s maintenance condition was stable for several years but has now deteriorated in specific areas that require immediate attention. With a recorded 46,551 miles on a 2004 model, the average annual mileage works out at roughly 2,100 miles per year, which is considerably below the typical UK usage of 7‑10 000 miles per annum. Such low utilisation often points to long periods of inactivity or very gentle use, which can be beneficial for engine wear but may predispose components to age‑related degradation. Prolonged storage can lead to rubber hardening, corrosion of metal parts, and electrolyte depletion in the battery, while the lack of regular heating cycles may allow moisture to settle in the brakes and suspension bushings. The windscreen wiper failure should be inspected for blade wear, hinge stiffness and motor output; a wiper that does not clear effectively can compromise visibility in rain and may indicate a failing motor or worn linkage that could become noisy or seize under load. The tyre‑to‑arch rubbing is a more serious concern – it may be caused by an out‑of‑size tyre, incorrect inflation, or a mis‑aligned suspension. A thorough visual check of the tyre sidewalls for cuts, cracks or excessive wear, measurement of tread depth, and verification that the tyre size matches the manufacturer’s specification are essential. A test‑drive should reveal any steering pull, vibration, or clunking that would confirm alignment or suspension issues, and the arch liner should be examined for abrasion or damage that could lead to rust on the bodywork. Given the vehicle’s age and low mileage, the buyer should also conduct age‑related inspections irrespective of the MOT findings. Examine all tyres for sidewall cracking or dry rot, as rubber can deteriorate even without mileage. Check the battery’s charge and electrolyte level, and consider a load test to ensure it can sustain a cold‑weather start. Inspect the brake discs for surface corrosion or uneven wear that could cause shudder, and verify that the calipers move freely without binding. Look for signs of fluid degradation – darkened engine oil, coolant, and brake fluid – and confirm that the service book shows timely oil and filter changes, as calendar intervals are as critical as mileage for these consumables. A careful visual appraisal of suspension bushings, rubber mounts and exhaust hangers for cracking or corrosion will help gauge whether the car has been stored in a dry environment or exposed to the elements for extended periods.
