Warning light on? We find the cause, then prove it.

Warning lights and intermittent faults read with main-dealer level equipment — then proved on the car before we quote, so you're not paying for guesses.

Reasons to get it checked

  • Engine management light has come on
    A fault has been logged. The code points to where to look — it isn't the answer on its own.
  • Loss of power or 'limp mode'
    The car is protecting itself. Best checked before it's driven far.
  • A fault that comes and goes
    Intermittent faults need live data and patience, not a parts-swapping exercise.
  • ABS, airbag or other system lights
    Safety systems — and MOT items — worth reading properly.
  • Rough running, stalling or hesitation
    Could be sensors, ignition, fuel or air. We trace which before quoting.
