Car Diagnostics Dublin – Fast & Honest Fault Checks in Tallaght
If a warning light has popped up on your dash, don’t ignore it – it’s your car’s way of telling you something’s wrong. At Michael and Sons Auto Service, we provide professional, affordable car diagnostics in Dublin using up-to-date scanning tools and good old-fashioned know-how.
We’re based in Tallaght, and we help drivers from across South and West Dublin get to the bottom of engine faults, electrical gremlins, and performance issues – without guesswork or jargon.
What Is a Car Diagnostic Test?
Modern vehicles are packed with sensors and systems that report errors through your car’s onboard computer (ECU). When something goes wrong, it often shows up as a check engine light, ABS warning, or emissions alert.
A diagnostic test allows us to plug directly into your car’s system, read the error codes, and see what’s going on beneath the surface. It’s quick, non-invasive, and can save you time and money by catching problems early.
When Should You Get a Diagnostic Test?
If you’re experiencing any of the following, it’s time to get your car checked:
- Engine warning light or “check engine” symbol
- Loss of power or hesitation when accelerating
- Poor fuel economy or misfiring
- Electrical issues – e.g. lights flickering, windows not working
- Irregular idling or stalling
- Dashboard lights staying on after start-up
- Emissions test failure (pre-NCT)
Even if there’s no light showing, we can run a full scan to check your engine, ABS, fuel system, gearbox, battery, and other critical systems.
What Our Car Diagnostics Cover
At Michael and Sons, we offer a full range of diagnostic checks, including:
Engine Diagnostics
We check for fuel injection faults, misfiring, timing issues, and internal sensor problems that affect performance or economy.
Electrical System Checks
From battery health to alternator output and wiring faults, we’ll find out what’s draining power or causing flickers and failures.
ABS & Airbag Diagnostics
If your ABS, traction control, or airbag lights are on, we’ll scan these systems and advise if a sensor or control module needs attention.
Emissions & Lambda Sensor Faults
Many NCT fails are down to oxygen sensors or emissions faults. We’ll pinpoint the issue and fix it ahead of the test.
Live Data Readouts
We can track how your engine performs in real-time, helping us identify intermittent issues you might not notice all the time.
Clear Answers, Not Guesswork
We don’t just plug in a scanner and hand you a list of codes – we explain clearly:
- What the issue is
- What caused it
- What needs to be done
- And whether it’s urgent or not
You’ll never be pushed into repairs you don’t need. We’ll give you honest advice, explain the options, and only proceed if you give the go-ahead.
