2004 Saab 9-5 2.2L Diesel · LD54 UTZ

Recurring issues with braking components and tyre degradation define the recent mechanical profile of this vehicle, despite a successful MOT pass on 6 December 2025. While the vehicle has maintained a consistent testing record since 2019, the most recent results highlight ongoing concerns regarding the condition of the brake discs. Specifically, both the nearside and offside front brake discs were flagged as worn, pitted, or scored. This follows a pattern established in October 2023, where pitted front brake discs were first noted as an advisory, suggesting that surface corrosion or material wear is a persistent factor for this vehicle. The recorded mileage of 53,322 miles represents a very low annual average of approximately 2,424 miles over its 22-year lifespan. This usage pattern indicates the vehicle has spent significant periods stationary or has been used only for very short, infrequent journeys. Mechanically, such low annual accumulation can lead to specific issues not typically seen on higher-mileage cars, such as the perishing of rubber components and the oxidation of metal surfaces due to lack of regular heat cycles and movement. The 2023 advisory regarding all four tyres being slightly damaged, cracking, or perishing is a direct consequence of this low-usage, long-term standing profile. Prospective buyers should pay close attention to the braking system during a test drive. Given the repeated advisories regarding pitted and scored discs, it is essential to check for any pedal judder or vibration when applying the brakes at various speeds, which can indicate disc thickness variation or warping. Additionally, listen for any grinding or squealing noises that might suggest the pads are interacting with heavily corroded disc surfaces. The presence of pitting often suggests that the vehicle sits for extended periods, which can also affect the condition of brake calipers and the movement of the pistons. Regarding the tyres, the history of cracking and perishing necessitates a physical inspection of the sidewalls and tread grooves for any signs of deep structural cracking, even if the tread depth appears sufficient. On the test drive, pay attention to any unusual road noise or a slight wandering sensation, which can occur if the rubber has hardened or if the tyre structure has degraded from age rather than wear. While the 2023 failure regarding a defective windscreen wiper and a reduced headlamp output was resolved, the recurring nature of the brake and tyre advisories suggests that components affected by age and inactivity are the primary areas of concern.
