2005 Suzuki Wagon-R+ 1.3L Petrol · FN05 TZB

A recurring theme of structural and underbody corrosion runs through every recorded MOT for this 2005 Suzuki Wagon-R+, with the front suspension assembly and rear coil springs appearing as advisories at every test since 2023. The most recent interaction on 18 March 2026 produced both a pass and a failure on the same day, the failure attributable to a split offside front outer CV joint boot that was no longer preventing the ingress of dirt. The pattern of advisories across the four recorded years shows a clear progression: 2023 and 2024 flagged corroded front and rear coil springs, 2024 added a corroded front anti-roll bar and a damaged offside rear shock absorber casing, 2025 introduced a corroded oil sump and an offside front strut, and 2026 has escalated the front strut corrosion to both sides alongside worn upper strut pin or bush wear. Combined with the recurring offside front brake pipe corrosion and the binding nearside rear service brake, the underbody is exhibiting widespread age-related deterioration that is steadily worsening rather than stable. Against a 21-year vehicle age, the recorded 81,522 miles equates to approximately 3,882 miles annually, which is substantially below the typical mileage for a city car of this era. Four tests are recorded at roughly annual intervals between March 2023 and March 2026, with no multi-year gaps that would suggest a prolonged period off the road, so the low accumulation is consistent with light, regular use rather than extended standing. This low annual mileage is mechanically significant because, as the advisory record demonstrates, low miles have not protected the underbody components from corrosion, and the chassis, suspension, and brake lines are the items actively deteriorating rather than the engine or drivetrain. For a prospective buyer, the priority inspection areas are clearly the front suspension and underbody. The Macpherson struts on both sides have been flagged for corrosion in 2026, with the upper pin or bush showing wear, so on a test drive listen for clonks or knocking from the front end over speed bumps and listen for any knocking or creaking when turning the steering to full lock both ways. The coil springs on the nearside front, offside front, and offside rear have been flagged across multiple tests, so any sagging of the vehicle's ride height, particularly at the rear offside, or a harsh, crashing response over uneven surfaces would indicate the springs have finally failed. The offside front brake pipe has been flagged for corrosion three years in succession, so the brake pedal should be checked for any spongy feel or excessive travel, and the pipework physically inspected for rust scaling, particularly at the flexi hose connection, which itself showed ferrule corrosion in 2026. Additional concerns to verify on inspection include the offside front outer CV joint boot, which was recorded as split in March 2026, so the offside front wheel arch should be inspected for fresh grease contamination and the joint listened for clicking on full-lock turns. The nearside rear service brake has been flagged as binding, which warrants a check for a hot wheel hub after a short drive and a possibly seized or sticking rear caliper or handbrake mechanism. Finally, the corroded oil sump noted in 2025 should be examined from underneath for any active drips or staining, and the offside rear shock absorber casing, which has slight external damage, should be checked for any fluid weeping, all of which are consistent with a 21-year-old vehicle where underbody corrosion is the overriding mechanical consideration.
