While it is possible to drive, doing so carries the risk of inflicting further damage to your vehicle, particularly on rough or pothole-riddled roads. In the worst-case scenario, you might encounter challenges in maneuvering your car to avoid potential collisions, making it a risk not worth taking.

Engine Malfunction Indicator: Significance and Response

Engine malfunction indicator

Also referred to as the check engine or ECU warning light, when the engine management light is illuminated, it’s often accompanied by noticeable indicators of engine malfunction, such as diminished power or stuttering during accelerator use.

This light can point to various faults, ranging from minor issues like a malfunctioning electrical sensor to more significant mechanical problems, such as faults within your emission control system or catalytic converter.

Is it safe to drive with the check engine light on?

If the check engine light comes on, it’s advisable to have it examined as soon as possible. Continuing to drive with the light illuminated poses the risk of causing additional, potentially irreparable damage to your engine.

Power steering warning light

Power steering warning light

Also referred to as the EPS (Electric Power Steering) warning light. This light suggests an issue with the power steering, and on Audi dashboards, it may appear without an exclamation mark.

For electric power steering, a quick fix might be as simple as restarting your car. Find a safe spot to stop, turn off the car, and wait for 30 seconds before restarting it. If the light persists, it’s essential to have your car checked promptly.

Is it safe to drive with the EPS light on?

You can, but if the power steering fails, you’ll experience difficulty in maneuvering the car. Exercise extra caution, especially at high speeds on the motorway, as driving without power steering assistance can be perilous.

Diesel Particulate Filter Warning Light

Continuing to drive with a blocked filter not only emits toxic black smoke but can also lead to substantial damage to your vehicle. It’s advisable to visit a garage for a check-up promptly, as replacing these filters can be costly.

How to reset Audi tyre pressure warning light

To reset tire pressure on contemporary Audi vehicles, access the onboard system, navigate to “Services and Checks,” choose “Tyre Pressure Monitoring System,” then “Tyre Pressures,” store the current pressure levels, and confirm by selecting “Yes.” This will reset your tire pressure.

How to turn off brake pad warning light Audi

When the brake pad warning lights illuminate on your dashboard, it signifies a critical issue that demands immediate resolution.

In cases where you’ve consulted a mechanic and the warning light persists, you can attempt a manual reset. To do this, disconnect the vehicle’s battery and let it sit for 30 seconds. Afterward, reconnect the battery and start your vehicle. If the warning light continues to appear, it indicates a persistent issue that should be addressed by a professional.

Brake pad warning light

brake pad wear warning light

Commonly known as the brake pad wear warning light, the appearance of this symbol indicates that a sensor has identified that your brake pads have reached a critically thin level.

Is it safe to continue driving when the brake pad light is illuminated?

This warning light is designed to activate before the brake pads reach a hazardous level of wear, allowing you ample time to arrange for their replacement. However, it is strongly advisable to have them replaced as soon as possible, as driving with completely worn-out brake pads can pose a significant safety risk.

Electronic Stability Problem (ESP) or Dynamic Stability Control (DSC)

Electronic Stability Control

Also recognized as Electronic Stability Control (ESC), this warning light is often represented by the initials ESP. It signifies a traction control issue. When it flashes, it indicates that the ESP system is actively intervening, such as during slippery road conditions. Should the light remain continuously illuminated, it suggests a malfunction in the ESP system.

In the event that the ESP system has been intentionally deactivated, the ESP light will display the word ‘OFF,’ which may occur inadvertently.

To confirm, attempt to halt and then restart the engine. If the light persists after the restart, it is advisable to have it examined at an automotive service facility, as the ESP system plays a crucial role in enhancing safety.

Anti-lock brake system (ABS) warning light


ABS serves as a vital safety feature, particularly in situations demanding sudden stops or challenging driving scenarios like icy road conditions.

Is it safe to continue driving when the ABS light is illuminated? If the ABS light illuminates on its own, your vehicle should still provide standard, non-assisted braking capabilities, permitting you to proceed with your journey safely. Nonetheless, exercise caution by maintaining a safe following distance and drive prudently, and arrange for a prompt inspection.

In the event that the ABS light activates alongside the brake warning light, it may indicate a potential brake system malfunction. In such a situation, it is imperative to cease driving immediately and seek assistance, especially if you possess breakdown coverage.
