2006 Toyota RAV-4 2.2L Diesel · LR06 YNU

A pattern of recurring advisories around corrosion, oil leakage, and emissions issues defines the mechanical trajectory of this 2006 Toyota RAV-4 across its recorded MOT history. The most recent test on 2025-10-08 returned a pass, but the submission immediately prior on 2025-09-30 failed on two major exhaust-related items: emissions exceeding the manufacturer's specified limit and visible smoke from the diesel particulate filter. That same exhaust defect had manifested two years earlier as a major leak at the offside rear joint in 2023, suggesting the rear exhaust and DPF system have been a chronic weak point. Alongside the emissions concerns, an offside front oil leak has appeared as an advisory on three consecutive tests spanning 2023, 2024, and 2025, and corrosion advisories on the nearside rear brake pipe have been repeated in 2022, 2023, and 2025, with the 2025 entry specifically noting corrosion up to the flexible hose. The rear sub-frame has also now entered the advisory record as corroded though not seriously weakened, signalling the early stages of structural surface oxidation that warrants monitoring. With 103,113 miles recorded over roughly twenty years, the vehicle has accumulated approximately 5,156 miles annually, which is notably low for its age. This rate of usage reduces wear on high-mileage items such as clutch assemblies and engine internals, but it also raises questions about whether the vehicle has experienced extended periods of standing, particularly as evidenced by tyre perishing advisories on multiple occasions and the recurring anti-roll bar linkage dust cover deterioration noted in 2022. Diesel particulate filters are particularly susceptible to underuse, as infrequent driving prevents passive regeneration cycles from completing, which aligns with the visible smoke and exceeded emission limits observed during the 2025 failure. The MOT record contains no significant gaps in testing, so the usage pattern appears continuous rather than interrupted by long-term off-road periods, and the mileage progression remains relatively flat year on year. Prospective buyers should focus their physical inspection on the specific components flagged throughout the record. The diesel emissions failure warrants a cold-start observation for excessive smoke, particularly blue or black smoke that lingers under load, and a road test should include sustained motorway driving at higher rpm to gauge whether the DPF can successfully regenerate. The offside front oil leak should be inspected by examining the underside of the engine for fresh oil residue and checking the oil level on the dipstick before any test drive, as a worsening leak could indicate failing crankshaft seals or gasket deterioration. Listen for timing chain rattle on cold start, which is a known weakness in this generation of Toyota diesel engines. Brake pedal feel should be firm without excessive travel, given the corroded brake pipe advisories, and the nearside rear flexible hose area should be examined directly for rust scaling or moisture damage. Suspension and steering refinement deserve close attention on a test drive given the anti-roll bar linkage dust cover defect from 2022 and the shock absorber misting advisory from the same test. Bumps and uneven surfaces should be traversed at low speed to detect knocking from worn bushes or droplinks, and any looseness through the steering wheel may indicate wear in the linkage assemblies that has progressed beyond the recorded advisory. The rear sub-frame corrosion should be physically inspected by looking under the vehicle at the mounting points and surrounding structure for flaking rust, scaling, or any perforation that could advance the advisory into a serious defect at a future test. Tyres should be checked for age-related perishing and sidewall cracking, as this has been flagged on multiple tests, and the front TPMS warning lamp that has been advisory since at least 2025 suggests either a faulty sensor or pressures that need addressing before any long journey.
