Engine warning lights

A check engine light or another dashboard warning means your car's computer has recorded a fault. Some faults are minor, others can cause damage if they are left. We find out which, so you can decide what to do next.

If the light is flashing, or the car is running roughly, stop driving and call us on 03 9548 9380.

Computer diagnostics, done properly

We connect a diagnostic scan tool to read the fault codes stored by the car. A code points to the system involved, not always to the part that has failed, so we then test that system to find the real cause before recommending a repair.

That way you pay to fix the actual problem, not to replace parts on a guess.

Electrical faults and wiring

Modern cars rely on a lot of wiring, sensors and control modules. We trace electrical faults back to their source and repair them.

  • Wiring and connector faults
  • Intermittent electrical problems
  • Lights and indicators not working
  • Blown fuses and faulty relays

Battery and alternator issues

A flat battery isn't always the battery's fault. We test the battery, the alternator and the rest of the charging system together, then replace only what has actually failed.

  • Battery testing and replacement
  • Alternator testing and replacement

Starting problems

If your car cranks slowly, clicks or won't start at all, the cause could be the battery, the starter motor, the ignition system or a faulty sensor. We test each one before replacing any parts.

Car won't start at all? 24/7 emergency towing is available to bring it to our Oakleigh South workshop.

Charging system repairs

A battery warning light, dimming headlights or a battery that keeps going flat can all point to a charging fault. We check the alternator output, belts, cables and connections, and repair the fault so the battery stays charged.

Every repair is quoted before we start. See also our mechanical repairs page.

FAQ

Vehicle Diagnostics Questions

My check engine light is on. Can I keep driving?

If it is steady, book in soon for a diagnostic. If it is flashing, or the car feels rough, stop driving and call us on 03 9548 9380, since damage may be happening.

How long does a diagnostic check take?

It depends on the fault. Reading the fault codes is quick, but tracing an intermittent electrical problem can take longer. Call us on 03 9548 9380 with your symptoms for a time estimate.

Do you fix the problem after diagnosing it?

Yes. Once we have found the cause, we explain what's needed and give you a quote. Repairs only start once you approve them.
