If a warning light has come on your dashboard, our team at MH Auto Repair Centre can help you understand what it means and check the fault behind it. We connect diagnostic equipment to your vehicle to read what triggered the light and explain it in plain English, rather than leaving you guessing. We’re based in Perivale, Greenford, and cover the surrounding West London area.
Message us on WhatsApp with a photo of the light and your vehicle details, and we’ll get a warning light check booked in.
What Is a Dashboard Warning Light Check?
A dashboard warning light check is how we work out what does a warning light mean for your specific vehicle. Modern cars use a range of dashboard symbols to flag everything from a loose fuel cap to a serious mechanical fault, and the same symbol can sometimes point to more than one cause. Rather than guessing from the symbol alone, we connect diagnostic equipment to your vehicle to read the fault codes and live data behind it. This check is one of several under our wider vehicle diagnostics range.
This warning light diagnostic tells us which system has raised the alert — such as the engine, brakes, battery or airbags — so we can confirm the actual cause rather than replacing parts on a guess.
Common Dashboard Warning Lights
We carry out dashboard light checks for a wide range of warning symbols, including:
- Engine management or check engine light
- Battery or charging system warning light
- Oil pressure warning light
- Coolant temperature warning light
- Brake system warning light
- ABS warning light
- Airbag (SRS) warning light
- Tyre pressure monitoring warning light
- A dashboard symbol you don’t recognise
If the check points to a specific system such as the engine, ABS or airbags, we’ll explain that clearly and advise on the right next step for that particular fault.
Red or Amber — Which Warning Lights Matter Most?
The colour of a warning light is a useful first clue. As a general rule, a red warning light usually means stop as soon as it’s safe to do so, since it can indicate a fault serious enough to cause damage or affect safety if you keep driving. An amber warning light is generally less urgent but still means the fault should be checked soon, before it has a chance to get worse.
A flashing light of either colour usually points to something more urgent than a steady one. If you’re ever unsure what a light means or whether it’s safe to keep driving, it’s best to get it looked at rather than wait.
How the Warning Light Check Works
- Tell us which warning light has come on, and whether it’s steady or flashing
- We connect diagnostic equipment to read the fault codes and relevant live data from your vehicle
- We explain what triggered the light and which system it relates to
- We provide a quote for any repair work before starting anything
- With your agreement, we carry out the repair and confirm the warning light has cleared before handing the car back
What Affects the Cost of a Warning Light Check
We don’t publish a fixed price for a warning light check, because it depends on the vehicle and what the fault turns out to be. Factors that affect the cost include:
- The make and model of your vehicle and which system has triggered the light
- Whether the cause is straightforward to trace or needs more extensive investigation
- Whether a repair is needed afterwards, and what parts or labour that involves
We’ll always talk you through the likely cost after we’ve had a look at your vehicle, and you’ll get a quote before any repair work goes ahead.

Warning Lights FAQs
What does it mean when a warning light comes on?
It means a system in your vehicle has detected something outside its normal parameters, and the dashboard symbol tells you roughly which system is affected. The exact cause can vary, so a warning light diagnostic check is the most reliable way to confirm what’s actually wrong.
What’s the difference between a red and an amber warning light?
A red warning light generally signals a more serious fault and usually means you should stop as soon as it’s safe to do so. An amber warning light is typically less urgent but should still be checked soon so the underlying issue doesn’t get worse.
How much does a warning light check cost?
The cost depends on the vehicle and the fault involved, so we don’t publish a fixed price. We’ll talk you through the likely cost once we’ve had a look at your car, and provide a quote before any repair work begins.
Can you tell me what a specific dashboard symbol means over WhatsApp?
Send us a photo of the symbol on WhatsApp and we can give you a general idea of what it relates to. A full warning light diagnostic check is still the only reliable way to confirm the exact cause for your vehicle.
Is it safe to keep driving with a warning light on?
It depends on which light and its colour. A red warning light generally means stop as soon as it’s safe to do so, while an amber light suggests getting it checked soon. If you’re unsure, it’s best to get it looked at rather than keep driving.
Do you fix the problem as well as diagnosing it?
The check itself identifies the cause rather than fixing it. Once we know what’s wrong, we’ll explain the findings and provide a quote, and our team can carry out the repair if you’d like us to go ahead.
