Audi glow plug warning light
The glow plug warning light is only seen on diesel Audis and is usually orange in colour. Like the conventional engine management light, it’s designed to alert drivers about faults with the emissions or running of the vehicle.
You’ll need to inspect the car further to see what’s gone wrong and it’s best to enlist the help of a professional.
Can I still drive with my Audi glow plug warning light on?
Although it’s possible to drive with the glow plug light showing, it’s not a great idea. If a problem with the engine is ignored it could develop into something much more serious and more expensive to repair.
Thankfully on the Audi dashboard, the glow plug light will begin to flash if a fault becomes more urgent and immediate action is needed.
If you’re covered by our roadside breakdown service our patrols will be happy to see how they can help.

Audi service warning light
Your car is due a service, it’s that simple.
The light may be triggered when your oil needs changing, a filter needs replacing, or when your engine has clocked a certain mileage. Think of it as a maintenance reminder rather than an emergency alert.
Can I still drive with my Audi service warning light on?
If you drive with a service warning light showing, you run the risk of a straightforward maintenance job escalating into something much more damaging. For example, if you fail to change your oil, engine parts are more likely to rub and knock under the bonnet and wear out quicker.
As always, it’s best to get your car looked at by a professional, either through the manufacturer or with an RAC approved garage.

Audi bonnet warning light
Your bonnet isn’t closed properly.
When this light shows you should safely stop your car and lift the bonnet before attempting to shut it again. The light should turn off when the bonnet has returned to a secure position.
Can I still drive with myAudi bonnet warning light on?
Driving with the bonnet warning light on could end badly. You should act quickly and calmly to prevent a gust of wind from pushing the bonnet in front of your windscreen and obscuring your view.
When it’s safe to do so, pull over and lift the bonnet before pushing it firmly back into place.
Audi pre sense warning light
Audi’s clever pre sense technology uses sensors to predict an imminent crash and put your car’s safety features to work. Seat belts may be fixed to reduce your chances of moving around the car after a collision and hazard lights are automatically switched on to alert other drivers about potential danger.
The pre sense light will illuminate when there’s a problem with its sensors. Try familiarising yourself with their position so you can wipe away dirt or remove an obstruction if the warning light appears.
Can I still drive with my Audi pre sense warning light on?
Driving with a faulty pre sense system means making a journey with fewer safety features. Lane keeping technology, collision avoidance assist and more safety features could go to waste.
A visit to an Audi dealership or an RAC approved garage is your best bet for making the most of your car’s most important technology.

Audi gearbox/clutch warning light
This light will illuminate when there’s a fault with the gearbox or clutch. It normally appears with a message on the information system behind the steering wheel, to give more details about the problem.
In some cases, the light can appear red. If this happens you should stop when it’s safe to do so and contact an RAC approved garage immediately.
Can I still drive with myAudi gearbox/clutch warning light on?
If you ignore the gearbox/clutch warning light you might find it difficult to shift gears. It may sound like a minor inconvenience, but the problem could prove dangerous in certain driving scenarios, for example, on hill starts.
Minor gearbox problems can be easily fixed but if you put off the warning signs you might need an expensive rebuild or replacement.
