Don’t Ignore a Flashing or Solid Check Engine Light.

Trust Dundas Automotive to Diagnose and Fix The Problem

Your vehicle’s check engine light is designed to keep you informed of the condition of your engine and warn of any issues that should be looked into. It monitors many aspects of the vehicle: emissions controls, transmission shifting, engine and fuel management, and even more in the cases of luxury or hybrid vehicles.  Dundas Automotive  provides check engine light repair and complete diagnostics for all makes and models of cars, light trucks, SUVs, crossovers, vans and RVs.

When the check engine light comes on, it is a malfunction indicator. It does not mean you “just need an oil change or tune-up.” It’s not a service reminder and rarely has anything to do with routine maintenance. Diagnosis of a check engine light requires more than simply pulling a fault code and replacing some parts. We fully diagnose what is wrong, then we review our results with you before we begin replacing parts or doing further work.

In most cases, the technician must go through a complicated diagnosis flow chart procedure to not only track down the problem, but to also determine why it happened in the first place so it can be repaired properly and not be a recurring problem for you.

If the check engine light is on solid, and the car seems to drive normally, the problem is not an urgent concern. You can schedule a convenient time to bring your vehicle in for evaluation

Check Engine Light Repair
If the check engine light blinks, or the car bucks, hesitates, loses power, or any similar driving concern – DO NOT continue to drive the vehicle. Further driving will very likely cause significant damage to components. Contact Dundas Automotive  immediately at 519-455-9470

Why Do We Charge for Diagnostics Labor?

VERY IMPORTANT! SIMPLY KNOWING A CODE THAT THE COMPUTER RECORDED FROM YOUR CHECK ENGINE LIGHT DOES NOT DETERMINE WHAT IS WRONG WITH THE VEHICLE. There are certainly devices that you can buy to tap into your onboard computer yourself to pull a code, and there are companies advertising that they will pull a code for free. The code alone is simply a reference to the affected system and does not tell you what is exactly wrong with the vehicle. You need a professional and qualified technician to fully diagnose the root of the issue.

  • State-of-the-art diagnostic equipment including manufacturer specific scan tools
