2004 Toyota RAV4 2.0L Petrol · OU54 XUB

A persistent pattern of brake pipe corrosion advisories spanning from 2018 through the most recent test in August 2023 represents the defining mechanical concern on this 2004 Toyota RAV4. Across seven recorded MOT tests over six years, the nearside rear and offside rear brake pipes have been flagged at every single examination, progressing from "slight corrosion" in 2019 to corroded material covered in grease or other substance by 2022 and 2023, suggesting either an attempt to seal the deterioration or simply further degradation of the protective coating. A separate failure in May 2019 for headlamp aim being too high on both sides, corrected the same day and recorded as a pass, sits alongside repeated minor headlamp lens defects and confirms the lighting components have aged predictably. The exhaust system has also drawn advisories across multiple tests, with a minor gas leak noted in both 2021 and 2022 plus corroded rear flanges flagged in 2018, while the front shock absorbers have shown light oil misting on the nearside for two consecutive years, all consistent with a vehicle entering its third decade of service where sealing components and underbody ferrous items begin to deteriorate. With 86,385 miles recorded against a 22 year age, this RAV4 has averaged roughly 3,927 miles per year, a notably low annual accumulation that suggests either limited regular use or extended periods of standing between tests. The MOT cadence itself is revealing, with tests recorded in 2017, 2018, 2019, 2020, 2021, 2022 and 2023, showing consistent annual testing which implies the vehicle has been kept on the road continuously rather than laid up, yet the slow mileage build means many components such as the clutch, drivetrain and internal engine wear items have likely seen less mechanical stress than the calendar age alone might suggest. Conversely, long-standing low use can accelerate corrosion on underbody components due to moisture sitting on ferrous surfaces without the heat of regular operation drying them off, which aligns directly with the recurring brake pipe advisories and exhaust flange corrosion noted across the record. Any prospective buyer should physically inspect the underbody with the vehicle raised, focusing closely on the rear brake pipes running along the chassis and axle lines for any active rust scaling, perforation, or flaking that goes beyond surface discolouration, as grease covering corrosion can mask the true extent of metal loss. The front suspension warrants equal attention, given the anti-roll bar mounting bushes were flagged as worn in 2020 and a lower anti-roll bar link ball joint dust cover was recorded as split in 2018; on a test drive, listen for clonking or rattling noises over speed humps and uneven surfaces, particularly from the front end, and feel for any vagueness or knocking transmitted through the steering wheel that could indicate further deterioration of those bushes or the shock absorber upper mounts. On the test drive specifically, brake pedal feel should be assessed for sponginess or excessive travel which could indicate a brake fluid renewal is overdue given the vehicle's age, while the exhaust should be listened to at idle and under light load for any ticking, blowing or hissing sounds that would confirm the advisories noted in 2021 and 2022 have not progressed to a more serious leak. The headlamp aim issue recorded in 2019 and the persistent lens defects should also be verified in person by checking the beam pattern against a wall in the dark and inspecting the polycarbonate lenses for heavy pitting or internal condensation, as the MOT record shows these have not been replaced. Finally, given the low annual mileage and 22 year age, the buyer should budget for proactive replacement of the rear brake pipes, an exhaust section repair, and likely renewal of the front shock absorbers even if they are not yet failed, as the three-year continuous advisory history indicates these items are on a predictable deterioration curve. A compression test and inspection of the timing chain condition would also be prudent given the low mileage spread over such a long period, as intermittent use can occasionally lead to oil drain-down issues in engines that are not run regularly enough to maintain optimal lubrication.
