2003 Isuzu D MAX Auto Rodeo 3.0L Diesel · M6 CWL

A persistent theme throughout the MOT history is corrosion – notably on the front and rear brake hoses, several brake pipe sections and the chassis mounting points – together with a small, ongoing flexi‑pipe exhaust leak. The most recent September 2025 test was passed, but the same corrosion advisories re‑appeared, indicating that while the defects have not yet reached a failure threshold, they are chronic and have not been remedied over the past three years. At 44,100 mi the van averages just under 2,000 mi per year, a mileage figure that is unusually low for a 23‑year‑old commercial vehicle. Such light use often points to long periods of inactivity, which can accelerate rust formation on brake lines, pipework and chassis sections, especially in a climate that encourages moisture build‑up. The low‑kilometre count does not offset the risk that standing idle has contributed to the observed corrosion, and it also means that wear on consumables such as tyres, suspension bushings and brake pads may be less advanced than the age alone would suggest. When you inspect the unit, give the brake hoses a thorough visual and tactile check – look for surface rust, hardened ferrules and any signs of cracking or swelling. Pump the brake pedal; it should feel firm and return promptly without a spongy bottom‑end, and there should be no external fluid seepage around the hose connections. Listen for any hissing or whistling under acceleration that could betray a worsening flexi‑pipe leak, and feel for exhaust fumes inside the cab, especially when the engine is idling. A quick shake of the rear leaf springs should reveal any excessive play or rust‑induced weakening; any rattling or a noticeable sag under load would merit immediate attention. Given the pattern of advisories, a prudent buyer should budget for replacement of the front and rear brake hoses and the associated ferrules, as well as a new exhaust flexi‑pipe to eliminate the minor leak. Addressing the chassis corrosion around the mounting points – by cleaning, treating and, if necessary, reinforcing the affected areas – will help preserve structural integrity. Finally, verify that the parking brake still meets efficiency standards and that the rear leaf springs are free of severe rust, as these components are critical for safe load‑carrying and overall stability.
