Some of the common faults we get asked to look at include:

  • poor running – petrol and diesel
  • misfires
  • complete non-start
  • all common warning lights.

If a warning light comes on, it is because it has detected a fault within the system, failure to address this quickly can lead to further, more costly repairs, as can incorrect diagnosis which often results in replacement of unnecessary parts and increased labour charge.
