The following highlights some of the common vehicle dashboard warning lights and messages found in modern vehicles; there are many more and we are equipped to read and identify all of these for all manufacturers.

Depending on your vehicle and it's facilities these are typically displayed on the dashboard, in the vehicle driving information system within the dashboard and possibly the LCD information system where fitted.

Vehicle Diagnostics and Fault Repair

OK, so one of the lights is on or you are receiving a fault message on your car? Continous indication of a fault must mean there is a problem with the system in question. To identify and resolve the problem we need to connect your car to one of our Diagnostics Computers, read the code, and identify the fault.

Our packaged diagnostics service includes reading and clearing the fault code, initial diagnosis and advice on a permanent resolution. Read more Vehicle Diagnostics Package here.

Diesel Particulate Filter Fault Indicatordpf-b

DPF Diesel Particulate Filter system

Advice: Bring the car in as soon as possible for at least a diagnostic check. Continuos use can lead to potentially avoidable, expensive, repair bills.

This indicator is only applicable to Diesel vehicles. When illuminated this indicates the DPF filter has been unable to regenerate (clean itself) and must be regenerated manually.

The vehicle MUST be checked and the DPF manually regenerated to prevent further, possibly expensive, damage to the filter (a replacement DPF filter can cost from £500 to £2000).

ABS Check Light

ABS (Anti-lock Braking System) system warning

Advice: Do not drive continously with this illuminated. Your ABS braking system is not operating correctly.

The ABS (Anti Lock Braking System) warning will typically illuminate for a short period when the ignition is turned on and the system is checked.

In addition, the indicator will flash if the the ABS system is activated (during heavy braking etc.).

Continuous illumination or flashing when not breaking indicates a fault and possibly the ABS will have been de-activated. At this stage you must have the system checked to identify the problem.

Leaving the system unchecked may cause further damage to the system and could invalidate your insurance in the event of an accident as this indicates the braking system is not fully operational.

Vehicle battery warning light

Battery / Charging / Electrical System Fault

Advice: The battery may not be charging and the car will eventually not start. Continued driving could cause further damage.

The Battery/Charging system indicator will typically illuminate for a short period when the ignition is turned on and the system is checked.

Continuous illumination indicates a problem with the battery/charging or ignition system. At this stage you must have the system checked to identify the problem.

Leaving the system unchecked may cause further damage, particularly where the battery is concerned, and difficulty in starting the vehicle.

Vehicle brake warning light

Braking System Fault

Advice: Ensure the handbrake is off. Do not drive with illuminated as your ability to brake and stop maybe impaired during a journey.

The braking system/handbrake indicator will typically illuminate when the ignition is turned on and the system is checked.

The light will remain illuminated whenever the vehicle handbrake is applied.

If the light stays on continuously while driving this can indicate the handbrake has been left engaged (ensure the handbrake is off!).

If the handbrake is off illumination indicates a fault with the braking system that should be checked immediately to ensure the correct operation of the braking systems.

Leaving the system unchecked may cause further damage to the system and could invalidate your insurance in the event of an accident as this indicates the braking system is not fully operational.

Car Engine Diagnostic Indicator Light

Engine Management System Fault

Advice: Have the vehicle checked as soon as possible. Continued driving may cause further expensive damage or your vehicle will fail to start.

The Engine Management Indicator will typically illuminate for a short period when the ignition is turned on and the system is checked.

If the light stays on continuously this indicates a problem with the engine management system and should be checked at the earliest opportunity.

While driving the vehicle is usually OK for short periods, the engine will not be running at its optimum and the system should be checked as soon as possible. You should also check for possible overheating of the engine and avoid long journeys.

Leaving the system unchecked may cause further damage and will invalidate your warranty if not dealt with rapidly.

Yellow low oil warning light

Red oil check light

Engine Oil Level / Pressure Fault

YELLOW = Low engine oil pressure - top up as soon as possible

RED = Dangerously low engine oil pressure - continued driving risk permanent engine damage

Advice: Check the engine oil and top up with the correct type as soon as possible. Continuing to drive risks further engine damage.

The engine low oil pressure indicator will typically illuminate for a short period when the ignition is turned on and the system is checked.

Continuous illumniation indicates low engine oil pressure and you should check the levels of the engine oil and top up accordingly, or visit us and we will gladly check and top up as required.

When topping up with oil always ensure the correct type and grade of oil is used; failure to follow manufacturers guidelines and using incorrect oil can damage your engine and could invalidate your warranty.

Failure to check the oil and top up accordingly can cause severe engine damage.

Vehicle traction control warning light

or

Vehicle traction control warning light

Traction Control / Stability Programme Fault

Advice: Your stability / traction control system is impaired. Have the system checked as soon as possible to avoid long term damage.

The Traction Control / Stability Programme light is only applicable to cars fitted with Traction Control, Sometimes referred to as "Stability Programme" and "Dynamic Stability Control (DSC)" and may vary between manufacturers.

This typically illuminates for a short period when the ignition is turned on and the system is checked.

The indicator will flash when the system is activated (during heavy breaking, cornering, slipping in snow or on mud etc.).

Vehicles equipped with a button to deactivate the system, and in this case the indicator will illuminate to warn the driver the system is off.

An indicator lit even when activated, flashed continuously or generally more apparent than usual may indicate a problem with the control unit itself or the braking system / engine management system and it should be checked as soon as possible.

Vehicle tyre pressure warning light

Tyre Pressure Fault (TPM)

Advice: Check all tyre pressures and reset the system. Continued fault indicates a puncture or system fault - have checked as soon as possible.

This indicator is only applicable to cars fitted with tyre pressure monitoring systems and is usually accompanied by a graphic display and audible warning.

The Type Pressure Monitor (TPM) typically illuminates for a short period when the ignition is turned on and the system is checked.

Continued illumination, typically accompanied by a warning tone, indicates one or more of the tyres has suffered a tyre loss and should be checked. This could indicate a sudden puncture or slow air leak.

If the tyres appear OK but the warning persists, or one or more of the tyres has recently been changed, this could indicate a problem with one of the tyre sensors, or that the system needs to be reset.

Initial diagnosis can be completed by "resetting" the system; however this should only be completed once the tyre pressures have been checked.

For ongoing problems we can diagnose any tyre or sensor problems and reset the system accordingly.

NOTE:

Many of these indicators maybe accompanied by audible warnings, or where digital displays / On Board Computer systems etc. are installed a warning message to indicate the area of concern. However they are displayed, each area should be correctly investigated and remedied as soon as possible to avoid causing further damage.

This list is far from exhaustive and modern cars may have further indicators and systems. At Advanced Motorcare we have access to the tools and knowledge to analyse and interpret the causes of these problems and advise accordingly.
