Car diagnostics and check engine light in Montréal
An error code is not a diagnosis. It tells you where to look, not what to replace. Our method combines code reading, live data, component testing and experience, so parts don't get swapped blindly.
Our method
We read codes from every module, not just the engine. We analyse live driving data, test the suspected component, then confirm the cause. You get a clear finding and a repair quote, whether or not you choose to have the work done here.
Steady or flashing light?
A steady check engine light means book soon. A flashing light usually signals misfires that can damage the catalytic converter: slow down and call us before driving further.
What's included
- Code reading from all modules
- Live data analysis
- Testing of the components involved
- Clear report of the cause
- Detailed repair quote
Frequently asked questions
Is there a charge for diagnostics?
Yes, a real diagnosis takes time and equipment. You get the price before we start, and it is not credited toward the repair: it is a job in its own right.
Can you just clear the code?
We can, but the light will come back if the cause is still there. Clearing a code without understanding it hides the problem instead of fixing it.
Do you diagnose hybrid vehicles?
Yes, for general electronic diagnostics. Work on the high-voltage system is assessed case by case.
