2004 Toyota RAV 4 2.0L Petrol · DF04 WNP

A twenty-two-year-old Toyota RAV4 carrying a cumulative 88,912 miles presents an MOT history dominated by outright passes, but the two failures that did occur are mechanically instructive rather than routine. In 2021 the vehicle failed on both rear brake pipes being recorded as excessively corroded, a defect that speaks to the well-known vulnerability of underbody hydraulic lines on cars of this vintage, particularly where salt exposure and accumulated road grime accelerate external oxidation. The 2023 failure combined a lambda sensor reading outside specification with a major leak from the rear exhaust section, alongside an advisory that the rear brake pads were wearing thin. The fact that the vehicle returned to roadworthy condition at the very next attempt and has subsequently passed three consecutive tests with no recorded defects, including the most recent examination on 14 January 2026, suggests the corrosion and exhaust issues were resolved rather than allowed to develop into chronic faults. The usage profile of this RAV4 is unusually light for its age, with an average annual accumulation of roughly 4,041 miles since first registration. This figure is markedly below the typical mileage for a vehicle of this vintage and points to either periods of limited daily use or extended intervals when the car may have been stationary. The MOT testing pattern shows fairly regular annual examinations from 2021 onwards with no significant multi-year gaps, which is reassuring, but the relatively low mileage does carry particular mechanical implications for a car now well into its third decade. Components that suffer from underuse rather than wear, such as the rear brake calipers, brake flexings, and the lambda sensor circuitry, can deteriorate through corrosion and oxidation even when mileage accumulation is modest. The advisories recorded in 2024 for both rear tyres wearing close to the legal limit and on their edges also warrant attention, as low-mileage vehicles often sit with uneven weight distribution on tyres that age-harden before they physically wear through. For a prospective buyer, the priority areas for physical inspection are the underbody brake and fuel lines, given the 2021 failure on the rear pipes. A thorough check beneath the vehicle for any fresh corrosion, blistering, or weeping along the length of all four brake lines and their unions is essential, paying particular attention to the rear sections near the axle and where lines pass over the chassis rails. Any signs of recent replacement or underseal masking could be acceptable, but the buyer should establish whether the work was documented. The rear brake pads flagged as wearing thin in 2023 should be verified as having been replaced, and the condition of the rear brake discs assessed for lipping, as corroded calipers on a low-mileage car can cause uneven pad transfer and bind. On test drive, listen for any scraping or grinding from the rear under braking, feel for a soft or spongy pedal suggesting further pipe degradation, and check that the handbrake holds firmly on an incline as corroded rear mechanisms are common on vehicles that have stood. The exhaust system and emissions warrant close attention following the 2023 lambda and rear section failure. Inspect the rear silencer and connecting joints for any signs of replacement weld patches, blueing from heat, or fresh black soot deposits that would indicate a current leak. With the engine running, listen for any ticking or popping from the rear box that would betray a compromised seal, and watch for any flickering of the engine management light on idle, which can suggest the lambda sensor or its wiring is once more drifting out of specification. The rear tyre wear pattern noted in 2024 should also be re-examined; edge wear on both rears simultaneously can point to incorrect tracking, sagging rear suspension bushes, or simply age-related rubber deterioration, and a four-wheel alignment check should be considered before any new tyres are fitted. Finally, given the low annual mileage, the buyer should verify that the timing chain or belt interval, coolant, and transmission fluid have been replaced on a calendar basis rather than purely by mileage, as age-related degradation of these items will not be reflected in the MOT record but represents the principal remaining mechanical risk on a low-use RAV4 of this age.
