Check engine light on? Start here

A flashing check engine light means stop. It often points to a misfire that can damage the catalytic converter. Pull over when it’s safe and call your nearest shop.

A steady light is less urgent, but don’t ignore it. Check that the gas cap is tight, then book a scan. We have diagnostic tools for all makes and models. We read the fault codes, test to find the real cause and tell you what we found.

When to book a scan

  • The light is flashingEase off, pull over when it’s safe and call us.
  • The light came on and the car runs rough or has less powerThe fault is affecting how the engine runs. Book it in now.
  • The light came on but the car feels fineIt can be minor. It can also be the start of something bigger.
  • The light comes and goesThe car’s computer usually keeps a record of the fault, so we can still read it.

Why not wait on a warning light

It’s tempting to ignore the light when the car feels fine. A failing sensor is a cheap fix. The damage it allows when you keep driving is not.

How we diagnose it

A code is a starting point, not an answer. Here’s what happens when you bring the car in.

We read the codes

We connect our diagnostic equipment and read the fault codes.

We test the cause

A code points to a system. We test to find the real cause, not just the code.

We tell you what we found

You hear what’s wrong, in plain words, before any work starts.

We fix it

Once you give the go-ahead, we do the repair.

Doing the job yourself? Our parts counters can supply ignition parts and filters. Request a part or see auto parts.

What sets the price

A diagnostic visit has two parts: finding the cause, then fixing it. Here’s what moves the price of each.
