Expert verdict

Emissions & leaks: 2.0× the national share

Emissions & leaks make up 10.8% of everything recorded on the 2003 Vauxhall Omega, against 5.5% nationally — 5.3 points above. Suspension is still the single largest share at 23.4%, but at 21.0% nationally that one is ordinary. A smoky diesel or a leaking joint fails on emissions more often than on wear, so ask for a recent emissions printout.

Before your test

Three checks worth doing on a 2003 Omega

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the lights 6.1% of tests

    “headlamp lens slightly defective”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

  2. Check corrosion 4.7% of tests

    “component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength”

    Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.

  3. Check the brake pipes 3.2% of tests

    “rigid brake pipes excessively corroded”

    Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
