Warning light on? We find out why

Scanning is where diagnosis starts, not where it ends. We track the fault back to the cause so the light stays off.

A code is a clue, not a diagnosis

Plugging in a scanner takes a minute and gives you a code. The code points at a system, not at a broken part. A code naming an oxygen sensor can be a failed sensor. It can equally be an exhaust leak, a vacuum leak or a wiring fault making a perfectly good sensor read wrong.

Replacing parts because a code mentioned them is how people spend real money and still have the light on. We do the testing that tells the difference, then quote you on the actual cause.

What we can chase down

  • Engine warning lights, including intermittent ones
  • Running faults: misfires, rough idle, flat spots, poor economy
  • ABS, traction control and airbag warnings
  • Battery drain and charging faults
  • Electrical gremlins, the ones that only happen on cold mornings
  • Faults another workshop has already thrown parts at

About that light

A steady engine light generally means a fault is stored and the car wants looking at, but it is not usually an emergency. A flashing engine light is different. It typically indicates a misfire serious enough to damage the catalytic converter. Continuing to drive can turn a modest repair into an expensive one. If yours is flashing, ring us before driving further.

Worth knowing: a loose or failed fuel cap really can trigger a light, so check yours is on properly before assuming the worst.

Questions we get asked

Can you just read the code for me?

We can, but the code alone rarely tells you what to fix. It names a system, not a failed part. The value is in the testing that follows. That is what stops you buying parts you did not need.

My engine light is flashing. Is that different?

Yes. A flashing light usually means a misfire bad enough to risk damaging the catalytic converter, which is an expensive part. Stop driving where you safely can and give us a ring.

Another workshop replaced parts and the light came back.

That happens when parts get replaced off the back of a code instead of a diagnosis. Bring it in and tell us what has already been done, so we start from what is left rather than repeating it.

Can a warning light be something trivial?

Sometimes. A fuel cap that is not sealing is a well known one. That is exactly why it is worth finding the cause before spending anything.
