2004 Alfa Romeo 156 1.9L Diesel · WN04 LUH

The most recent MOT on 4 December 2025 was passed with no recorded defects, indicating that the vehicle currently satisfies the statutory safety and emissions requirements. However, the advisory record over the last eight years shows a clear accumulation of corrosion‑related items – rear coil‑spring and mounting corrosion from 2018 onward, progressive rear‑suspension mounting corrosion, and more recent concerns such as a cracked rear‑exhaust mount, steering‑rack inner joint play and a deteriorating front brake hose. While none of these have yet caused a failure, the pattern suggests a gradual decline in component condition rather than an improvement, and the vehicle is now approaching a point where remedial work may become mandatory. At 68 544 miles on a 2004 model the average annual mileage works out at roughly 3 100 mi per year, which is considerably below the typical UK usage rate for a car of this age. Such low utilisation often reflects long periods of inactivity or very light use, both of which can exacerbate age‑related deterioration such as rubber hardening, battery sulphation and corrosion of mounting points that are not being regularly flexed. There are no obvious spikes in mileage that would indicate a recent high‑stress period, so the wear on consumables such as clutch discs, timing belt (if fitted) or CV joints is likely to be limited, but the vehicle’s components have been exposed to calendar ageing for more than two decades. A prospective buyer should give particular attention to the rear suspension assembly: inspect the coil springs, spring seats and mounting brackets for any signs of rust penetration, cracks or loss of structural integrity, and verify that there is no excessive rear‑wheel play when the wheels are rocked. The steering rack should be checked for any looseness in the inner joints – a noticeable wobble or vague feel when turning the wheel at low speed can indicate the advertised play. The off‑side front brake hose must be examined for surface cracking or hardening, and the brake discs should be inspected for uneven wear or surface rust that could cause shudder under braking. The cracked rear‑exhaust mounting should be probed for movement; a rattling noise on acceleration or over bumps would confirm the defect and may require a new mount or exhaust repair. Given the vehicle’s age and low mileage, additional age‑related checks are essential. Examine both front and rear tyres for sidewall cracking, dry rot or perishing, even if the tread depth appears acceptable, and replace any tyre that shows signs of age‑related degradation. Test the 12‑volt battery voltage and load, as prolonged standing can lead to sulphation and reduced cranking power. Verify that engine oil, coolant and brake fluid have been changed within the recommended intervals – fluids can absorb moisture and lose effectiveness after several years regardless of mileage. Finally, request a complete service book; regular oil changes, timing belt (or chain) service and any previous suspension or steering repairs will give confidence that the car has been maintained in line with manufacturer guidance despite its modest mileage.
