Volkswagen Commercial Warning lights

If you own a Volkswagen commercial vehicle, it is imperative that you keep up with the maintenance of it. One of the biggest mistakes that vehicle owners make is only seeking professional servicing once their vehicle gives off some signs of distress. However, you can save yourself a lot of money in the long run by investing in regular servicing, as they will ensure that any issues with your commercial vehicle are picked up on before they turn into more expensive and troublesome ones.

Of course, your vehicle is also going to alert you if there is anything worrying going on. The vehicle dashboard will flash when there is an issue. Needless to say, though, some problems are worse than others! Some lights will require you to pull over and seek help urgently. There are then those that can be nursed until you are able to drive to your local VWCV Garage. With that in mind, it is important to make sure that you understand the warning lights on your commercial vehicle. Below, we will explain the different Volkswagen commercial warning lights and their meaning so you know the appropriate action to take if the lights start to flash on your dashboard.


Volkswagen uses a traffic light system

The good news is that Volkswagen has made it as easy as possible for you to determine the nature of the issue by using a traffic light system.

Red - If a red light flashes on your dashboard, this means that there is potentially a very serious problem with your vehicle. You should pull over as soon as it is safe for you to do so.

Amber - If an amber light flashes on the dashboard of your Volkswagen, it indicates that there is a problem that requires professional attention. While it is not as severe as a red light, you should not delay in getting your vehicle assessed by someone with the required experience and training.

Green - Green warning lights do not require action. Instead, they are for information purposes only.

Some of the different warning lights and their meanings

Now that you know about the different colour-coding for the Volkswagen commercial vehicle dashboards, it is imperative to take a look at some of the different types of warning lights and what they mean.​

VW brake system warning light

If the brake system light is flashing once you have fully released the parking brake. If it starts to flash while you are driving, this could either indicate that your Automatic Braking system is not working correctly or that the brake fluid level is low. When this light starts to flash, do not risk driving. Brakes are one of the most critical safety features for your vehicle, so it is crucial to act straight away when you see this red warning light.

VW engine cooling system warning light

This is another red warning light on Volkswagen commercial vehicles. If your coolant levels are running low and your engine is overheating, this light is going to come on. There are a number of reasons why this may happen. It could be that your system has a leak in it. However, it could be an indication of a much bigger issue, for example, a head gasket failure. You should make sure you stop your vehicle straight away. If you do not have enough coolant, your engine could end up getting so hot that it basically ends up welding itself together, and when this happens the damage will not be repairable.​

VW engine oil pressure warning light

The engine oil pressure warning light is an amber light. This will come on when the oil pressure or level is too low, or when the oil temperature gets too high. If the engine is not being lubricated by the oil successfully, this can lead to very costly or even irreparable engine damage. Therefore, it is vital to act with speed! When this light comes on, stop as soon as you are able to and switch the engine off. You should check the oil levels in your car and top them up if needed. If the oil levels are sufficient, it could be that you have a fault with the oil pump. If this is the case, you will need to use a recovery service, as you could cause some serious damage to your engine if you continue to drive your vehicle.

VW vehicle charging system warning light

If the vehicle charging system light comes on in your Volkswagen while you are driving, this is a sign that your battery is not charging correctly. There are several causes that could be possible here. In a lot of cases, it is a fault with the electrical system that causes this situation. However, it could also be as a consequence of damaged cabling, a bad electrical connection, a faulty battery, or a faulty alternator. When this happens, you will be able to keep driving your vehicle. Nevertheless, once the battery is drained, your vehicle  won't start. Therefore, it makes sense to get to a garage as quickly as possible before the battery dies.

VW ignition switch warning light

This warning light is designed to alert you if there is an ignition system malfunction. Of course, the ignition system has the role of enabling you to turn your engine off and on. Typically, this light will indicate that there is a mechanical fault. However, it could be that you have dirt stuck in your ignition switch, which is preventing the key from being turned properly. This light can either be amber or red. If it is red, drive to the garage right away, as once the ignition is turned off, you might not be able to turn it back on again

VW brake pad monitoring warning light​

If this light has started to flash on the dashboard of your  Volkswagen commercial​ vehicle, it means that the sensor has determined that your brake pads are too thin. This light should start to flash prior to the brake pads reaching the point that they are dangerously thin, so it means you are able to change the brake pads, but it is imperative that you do this straight away. It can be highly, highly dangerous if your brake pads wear out completely, so make sure you get this appointment booked in as soon as possible.

VW anti-lock braking system (ABS) warning light

Next, we have the VW anti-lock braking system (ABS) warning light. The ABS is a vital safety feature that is imperative if you find yourself needing to make an abrupt stop or if you are driving in conditions that are challenging, like flooding and ice. In terms of whether you need to stop immediately, it really depends on whether this light comes on by itself or another light comes on with it. If the brake warning light also comes on, it could be an indication that your brake system is failing, which means you need to stop immediately. However, if it comes on by itself, you should still have unassisted, normal braking, meaning you can continue your journey safety. Yet, you need to take extra care and keep your distance.

VW rear spoiler warning light

When your vehicle starts to speed up, a lift is generated. The rear spoiler generates downward force to counteract this, ensuring that your vehicle is kept on the ground firmly. Your vehicle could have an adjustable spoiler that can be raised when driving at fast speeds, for example, while on the motorway. The warning light is typically amber, and this will come on if there is a malfunction with a spoiler system, perhaps due to a faulty connection or fuse. If this happens, the spoiler system will be deactivated so that further damage is prevented. If this occurs, keep your speed down and get a service booked in as soon as you are able to. 


VW adaptive cruise control warning light

The final warning light that we are going to look at is the cruise control warning light. Cruise Control, when it is engaged, automatically keeps your vehicle moving at a speed you have selected. You can also make sure you maintain a safe distance from the vehicles ahead with ACC. Brakes will be applied automatically and if the gap gets too tight, you will be warned. The system is not working correctly if the amber light flashes. Stop your vehicle and restart the engine to see if this makes the light clear. If not, check for any dirt or ice blocking your sensors.
