Modern Volkswagen cars are filled with lots of sensors that monitor how each system in the car is behaving. The lights on the dashboard display what systems are in use and they also highlight when one of those systems is not working as it should.
Not sure what that yellow flashing symbol on your VW dashboard means? Read our guide to find out what each VW warning light means, why they come on, how urgent the problem is and what you should do when you see them.
If this red light remains on after you fully release the parking brake, or comes on when you’re driving, it could indicate that either the brake fluid level is low or that the Automatic Braking system isn’t working properly – in which case the ABS warning light will also be illuminated.
This is one of the more serious VW warning lights - and drivers should resolve this as soon as possible.
You shouldn't risk it. The brakes are one of the most important safety features of your car, so it’s important to act immediately when you see this red warning light.
If the red brake warning light comes on when you’re driving you should pull over and stop as soon as it’s safe to do so. Unless you know how to check your brake fluid levels yourself, this will be one for the professionals, so get yourself to a garage.
Don’t risk driving when your brakes aren’t functioning properly:call for recovery.
If you need assistance you can call the RAC on 03301 598 751 whether you are a member or not.

On VW cars, this is called the Emissions Control or Engine Management Lamp, but you’ll probably know it as the check engine light.
When the check engine warning light is illuminated it’s often accompanied by tell-tale signs that the engine is not working properly, such as a lack of power or stuttering as you press the accelerator. This light could indicate a number of faults, from minor issues like a broken electrical sensor to a much larger mechanical issue.
If the check engine light comes on you should get your car looked at by a mechanic. By continuing to drive with this VW warning light, you could risk causing further, potentially irreparable damage to your engine.

EPC is a computerised ignition and engine management system. This warning light - called the Petrol Engine Management Lamp on VW cars - usually signifies that there’s something wrong with the throttle system, and is often accompanied by other VW warning lights such as the check engine light or the stability control warning light.
You’ll probably notice that the engine is not functioning properly, and the car may feel sluggish to drive as the computer may automatically put the car into a ‘safe’ mode.
If the EPC light comes on you should still be safe to drive but you should proceed to get it checked out straight away to prevent further damage, as the severity of the problem could vary greatly.
Also known as the EPAS (electric power-assisted steering) warning light, this indicates a problem with the power steering.
If the power steering system fails you will notice that the car is harder to manoeuvre and you should take extra care – it could be dangerous to drive at high motorway speeds without power steering assistance.
For electric powered systems, this problem could be as simple to fix as rebooting a computer. Find a safe place to stop and try turning the car off and back on again. If the light stays on you should take your car to get checked as soon as possible.
The steering lock is an anti-theft device that prevents anyone who doesn’t have the keys from driving the car, by effectively locking the steering wheel in position if someone tries to move the wheel when the ignition is off.
A yellow warning light signifies that there’s a fault with the system that you should get checked out as soon as possible. If the light goes red while you are driving, you need to stop immediately and carefully, and call for roadside assistance, as the steering wheel could potentially lock into position and cause a potentially life-threatening situation.
If you need assistance you can call the RAC on 03301 598 751 whether you are a member or not.
This light will come on if there is a problem the with diesel particulate filter, which removes harmful soot from the exhaust gases to reduce emissions. It could indicate that the filter has become blocked with soot.
As well as releasing a plume of toxic black smoke every time you press the accelerator, driving with a blocked filter could cause more serious damage to your car. You should go to a garage to get it checked as soon as you can, as DPFs can be expensive to replace.
Learn more about Diesel Particulate Filters and how to maintain them.
This light will come on when coolant levels are running low and the engine is overheating. This could be due to a leak in the system or it could be a sign of a larger problem, like a head gasket failure.
If this light is red you should stop straight away, as without enough coolant your engine could get so hot that it effectively welds itself together, causing irreparable damage.
Stop and wait until the engine has cooled off before checking the gauge on the side of the coolant tank under the bonnet, topping up as required. Read our guide to checking your engine coolant.
While you’re under the hood, have a look to see if there are any obvious leaks. If you can’t see any and the light goes off after topping up then you should be fine to continue your journey. If the light comes back on again after topping up you should get it checked out at a garage to fix the underlying problem.
The yellow oil warning light comes on when either the oil temperature gets too high or the oil level or pressure is too low. If the oil is not lubricating the engine effectively it could lead to expensive or even irreparable engine damage, so it’s important to act quickly.
When this light comes on you should stop as soon as possible and turn off the engine. Have a look for any obvious oil leaks under the car, and then check the oil levels, topping up if necessary. If the oil levels are fine, then the oil pump may be faulty. In this case call the RAC for recovery, as driving any further could damage the engine.
Watch our video guide to checking your car’s engine oil.
Many VW cars are now fitted with tyre pressure monitoring systems that will let you know when the pressure falls. This could happen over time or it could be because of a puncture.
Yes, but you should drive with extra care and aim to top up with air at the next opportunity. Low tyre pressure can cause unsafe driving conditions so reduce your speed, and try to avoid braking suddenly or making any violent steering manoeuvres.
Most petrol stations and garages will have an air compressor you can use to check your tyre pressure. Top up the air in the tyres according to the vehicle manufacturer specification in your owner's manual.
If you have a puncture, watch our video to learn how to change a tyre in 10 simple steps.
If this warning light comes on you’ll probably notice that your VW car feels harder to handle, less stable, and it may be lower to the ground than normal. It could signal a leak in one of the inflatable bags that sit above the wheels and cushions your ride, or it could indicate a problem with the air compressor.
The severity of the problem will impact on your ability to drive safely. If the handling is poor you should stop as soon as it is safe to do so and call for roadside assistance.
Even if the handling is not adversely affected, without suspension the impact of any bumps or knocks will be transferred to the body of the car, and may cause considerable damage, so drive carefully to a garage to get it checked out as soon as you can.

If this light comes on in your VW when you’re driving it indicates that the battery is not charging. This could be due to a problem with your car’s electrical system and it could have several causes, such as a faulty alternator, faulty battery, bad electrical connection or damaged cabling.
Your car will run as normal until the battery is dead but once it is drained nothing in your car will work – so get to a garage quickly before you run out of juice!
This light warns you about a malfunction in the ignition system that allows you to turn the engine on and off. Usually it indicates a mechanical fault but it could even be dirt stuck in the ignition switch that is stopping the key from turning.
If this light goes yellow you should go to get the ignition switch examined as soon as possible to find out the cause. If it goes red, then drive immediately to a garage, as once you turn off the ignition, you may not be able to turn the car back on again.
ABS is an important safety feature that really comes into play when you need to make an abrupt stop, or when driving in difficult driving conditions like ice and flooding.
If the ABS light comes on by itself you should still have normal, unassisted braking, so it's safe to continue your journey – but keep your distance, take extra care, and get it checked as soon as possible. If it comes on with the brake warning light, it could indicate that the brake system is failing and you should stop straight away and call the RAC for recovery.
This warning light indicates a problem with traction control. If it’s flashing it means the ESP system is intervening – for example, if you’re driving on a slippery road. If the light stays on it means the ESP system is deactivated.
Since this system only kicks in when you're losing traction on loose ground or ice, you should be okay to drive with due care if you're on normal road surfaces.
You may have inadvertently turned off the ESP system. To check, try stopping and restarting the engine. If the light remains on after restarting get it checked at a garage as the ESP system is an important safety feature.
Adblue® is a type of diesel exhaust fluid. If this light turns yellow in your diesel VW it means the diesel exhaust fluid level is low, which will eventually prevent your engine from starting.
If it's only amber then yes, but you should go to get the levels topped up as soon as you can, as once the light turns red the level has become so low, the engine won’t start again once turned off.
This warning light may indicate a fault with your VWs transmission – often that the transmission fluid temperature is higher than normal – or it could serve as a reminder that your transmission fluid levels are getting low and need to be topped up.
Continuing to drive could cause more extensive damage and automatic transmissions can be expensive to replace. If you have the skills and confidence, you could check and top up the transmission fluid yourself but it’s wise to get any problems checked by a professional.
This light will come on if one or more of your brake lights has burned out.
You’ll need to get this replaced as soon as you can, not least because they’re an important safety feature but also because if you continue driving with a brake light out you may get pulled over the police. If this happens they could either give you a verbal warning, a notice to get the light fixed within 14 days, or even a fine and points on your licence.
Read our guide to checking your lights.
If this light comes it means that a sensor has detected that your brake pads are too thin. This warning light should come on before the brake pads become dangerously thin, so you have time to get them changed.
No, if your brake pads wear out completely it could be extremely dangerous. You should get them replaced as soon as you can - get your motor booked in with your nearest garage.
For more information read our guide to brake pads.
This light will normally turn on when your engine is warming up, however if it’s flashing this indicates that it’s not working properly and the glow plugs may need replacing.
No, you could damage the engine so get it checked by a professional as soon as possible. A fault with the glow plugs may put the engine into safe mode to prevent any damage to the engine so you may experience a noticeable drop in performance until the problem is fixed.
Modern VW cars may have a front assist system that monitors the traffic in front of your car, measuring the distance and relative speed of the vehicles ahead, to warn you if you get too close. It even prepares the brakes for emergency braking if it senses that you’re in danger of collision.
If the front assist warning light is yellow, this means that the system is not working properly, and you should drive with extra care and take your car for a service to get it fixed. This light will go red when it detects a risk of collision, and you need to take evasive action or brake to avoid a crash.
When engaged, Cruise Control automatically keeps your car moving at a speed chosen by you. The Adaptive Cruise Control (ACC) function will also allow you to choose a safe distance from the cars ahead. This system will automatically apply the brakes and warn you if the gap gets tight.
If the ACC light goes yellow it means the system is not working properly. Try stopping and restarting the engine to see if it clear the light. You could also check for ice or dirt that may be blocking the sensors. If the light stays on you’ll be fine to keep driving without ACC but you should take your car in for a service when you can to get it fixed.
When your car speeds up, it starts to generate lift. The rear spoiler creates downward force to counteract the lift, keeping your car firmly on the ground. Your VW may have an adjustable spoiler that can be raised when driving at high speeds, such as on the motorway, or lowered for a cleaner look when it’s not needed.
The yellow warning light will come on if the spoiler system is malfunctioning - perhaps due to a faulty fuse or connection. In this case the spolier system will have been deactivated to prevent further damage. If this happens you need to keep your speed down to a maximum of around 70mph and book your car in for a service to determine the problem.
