2002 DAX Rush 2.0L Petrol · E872 JAR

The defining mechanical story for this 2002 DAX Rush is not one of gradual wear but rather a pattern of intermittent exhaust emissions failures alongside long dormancy periods. The two recorded failures, both in August 2022 and August 2023, centre entirely on emissions readings: hydrocarbon content after the second fast idle, carbon monoxide at idle, and Lambda readings all falling outside manufacturer-specified limits. These are emissions-related defects which can stem from ageing catalysts, tired oxygen sensors, vacuum leaks, ignition faults, or stale fuel left sitting in the system. With the vehicle having passed its most recent test on 2023-08-10 immediately following the 2023-08-02 failure, the present emissions status may be marginal and warrants direct verification rather than assumption. The 2022 failure also recorded a parking brake inoperative on one side, suggesting the rear caliper mechanism or cable adjustment has been a point of concern, though it was not repeated in subsequent tests. With 7,494 miles recorded over approximately 24 years, the annual accumulation averages roughly 312 miles, an exceptionally low figure that strongly suggests prolonged periods off the road rather than gentle regular use. The MOT history supports this interpretation, showing a ten-year gap between the 2010-05-08 test and the 2022-08-17 test, with the vehicle apparently dormant from 2012 through 2022. Such extended standing periods are mechanically significant for a kit-built sports car of this nature: brake discs can corrode and bind, fuel systems can accumulate varnish and moisture, rubber components including fuel lines, suspension bushes, and drive belts can perish, and the 2009 advisory regarding perished fuel pipes is consistent with this. The mileage recorded across the six tests shows no progression whatsoever, indicating the odometer may not be functioning reliably or that the vehicle has effectively been moved only minimally between tests, both of which complicate any meaningful wear assessment. Prospective buyers should pay close attention to the exhaust and emissions system on any test drive. A Lambda sensor that is drifting or a catalytic converter that is failing will often present as rough idle, hesitation under load, or an unusually rich or lean exhaust smell. On the road, listen for misfires, flat spots during acceleration, or any illumination of the emissions-related dashboard warning lights. It would be prudent to inspect the catalyst, oxygen sensors, and any visible exhaust joints for physical damage or corrosion, and to confirm that the vehicle can currently meet the same emissions thresholds it passed in August 2023, particularly given the recurring nature of these failures across consecutive years. The brake system and parking brake mechanism also require direct inspection given the 2022 advisory regarding the nearside parking brake inoperative on one side. On a hill start, verify that the handbrake holds the vehicle firmly without pulling to one side, and during a low-speed manoeuvre listen for any binding or dragging from the rear wheels which would suggest seized caliper slides or a cable that has seized from disuse. Given the prolonged standing periods, also examine all visible rubber fuel lines for cracking or perishing as previously flagged in 2009, check the condition of the tyres for flat-spotting or sidewall cracking from age rather than wear, and test that all suspension components operate freely without clonks or sticking over uneven surfaces. Finally, an independent compression test and live diagnostic emissions check would be a sensible precaution before purchase, given that the only mechanical defects ever recorded have been emissions-related and the vehicle has covered so few miles that internal engine condition cannot be reliably judged from the odometer alone.
