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
Tip: 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.
If the light stays on continuously this 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 to 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 will invalidate your warranty.
Failure to check the oil and top up accordingly can cause severe engine damage.
DPF Diesel Particulate Filter system
Tip: Bring the car into iAutoUK as soon as possible for at least a diagnostic check. Continuous use can lead to potentially avoidable, expensive, repair bills.
This indicator is only applicable to Diesel engine vehicle. When illuminated this indicates the DPF filter has been unable to regenerate (clean itself) and must be regenerated manually.
The vehicle MUST be brought in to 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 over £2000 ).
ABS (anti-lock braking system) system warning
Tip: 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.
The indicator will flash if the the ABS system is activated (during heavy braking etc.).
Staying on continuously or flashing when not breaking typically indicates a fault and that 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.
Braking System Fault
Tip: Ensure the handbrake is off. Do not drive with illuminated as your ability to brake and stop maybe impaired now or 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 whilst driving this may indicate the handbrake has been left engaged (ensure the handbrake is off!).
If the vehicle handbrake is off this indicates a fault with the braking system and it should be checked immediately to ensure the correct operation of the braking systems.
Battery / Alternator / Electrical System Fault
Tip: 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 possible 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.
Engine Management System Fault
Tip: 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 light 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 possible problem with the engine management systems and should be checked and the earliest opportunity.
Whilst driving the vehicle is usually OK for short periods, the engine will not be running at it’s optimum and the system should be checked as soon as possible.
Leaving the system unchecked may cause further damage and will invalidate your warranty if not dealt with rapidly.
Traction Control / Stability Programme Fault
Tip: 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, Dynamic Stability Control (DSC)” and may vary between manufacturers.
This light typically illuminates for a short period when the ignition is turned on and the system is checked.
The light will typically flash when the system is activated (during heavy breaking, cornering, slipping in snow or on mud etc.).
Vehicles are usually equipped with a button to switch the system off, in this case the light will typically remain illuminated to warn the driver the system is off.
If the light remains lit even when switched on, flashed continuously or is generally more apparent than usual then you should have the system checked as soon as possible. This may indicate a problem with the control unit itself or the braking system / engine management system.
Tyre Pressure Fault
Tip: 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.
The Type Pressure indicator light typically illuminates for a short period when the ignition is turned on and the system is checked.
If the light remains illuminated, and typically accompanied by a warning tone, then 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 light remains illuminated, or one 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 reading your owners manual and “resetting” the system; however this should only be completed once the tyre pressures have been checked.
For ongoing problems we can diagnose any tyre problems, sensors and reset the system accordingly.
