Buying Tips for 2002–2003 Vauxhall Vectra C

  • Check every steering-column function because CIM faults can affect indicators, horn, wheel controls and even immobiliser behaviour.
  • On 1.9 CDTi diesels, look for swirl-flap or inlet-manifold history rather than assuming an engine light is a cheap EGR fix.
  • Run the heater blower through every speed and make sure the climate system works properly, because resistor and control faults are common.
