Volkswagen T5 Warning Lights – What Do They Mean?

The Volkswagen T5, part of the renowned Transporter series, is a versatile and reliable vehicle popular among commercial and private users alike. Like any modern vehicle, the T5 is equipped with a range of warning lights on its dashboard. 

These warning lights play a crucial role in alerting drivers to potential issues and ensuring the vehicle operates safely and efficiently. Understanding what each warning light means can help you address problems promptly and avoid further complications. 

This guide provides an overview of the key warning lights you might encounter on your Volkswagen T5 and what actions you should take.

The colour system explained

When it comes to warning lights, you’ll notice that they are split into three distinct colours – red, yellow/amber and green/blue. Here are the steps you should take for each warning light. 

πŸ”΄ Red warning lights: immediate action is required. Stop the vehicle and check the specific issue, such as brake fluid, oil pressure, or coolant levels. Seek professional help if necessary.

🟑 Yellow/amber warning lights: prompt attention is needed. Schedule a diagnostic check to identify and rectify potential issues with the engine, ABS, or DPF.

🟒 Green and blue warning lights: informational lights that do not indicate a fault. Ensure these lights function correctly to aid in safe driving practices.




Red Warning Lights

Brake system warning light

The brake system warning light is one of the most critical indicators on your dashboard. It typically appears as an exclamation mark inside a circle, flanked by two brackets. If this light illuminates, it indicates a serious issue with your braking system, such as low brake fluid levels or a problem with the brake pads. 

You should stop the vehicle as soon as it is safe to do so and check the brake fluid level. If the problem persists, seek professional assistance immediately.

Engine oil pressure warning light

This light, often depicted as an oil can, signals low oil pressure. Low oil pressure can lead to severe engine damage if not addressed promptly. When this light comes on, stop the vehicle and check the oil level. 

If the oil level is adequate, but the light remains on, do not continue driving the vehicle. Instead, contact a professional mechanic to diagnose and rectify the issue.

Coolant temperature warning light

The coolant temperature warning light, usually symbolised by a thermometer or waves, indicates that the engine is overheating. Overheating can cause significant engine damage. If this light illuminates, you should stop the vehicle immediately, turn off the engine, and allow it to cool. 

Check the coolant level and top it up if necessary. If the engine continues to overheat, seek professional help to inspect the cooling system.

Yellow/amber warning lights

Engine management light (EML)

The engine management light, also known as the check engine light, appears as an engine block icon. It indicates an issue with the engine or emission control system. 

While the vehicle may still be drivable, it is advisable to have the engine checked as soon as possible to prevent further damage. A diagnostic scan can identify the specific fault code and guide necessary repairs.

ABS warning light

The Anti-lock Braking System (ABS) warning light, depicted as the letters "ABS," signals a problem with the ABS. While the regular braking system may still function, the ABS may not, affecting your ability to brake safely in emergency situations. Have the ABS system checked by a qualified technician to ensure optimal braking performance.

Diesel particulate filter (DPF) warning light

The DPF warning light appears as a box with dots in the centre. This light indicates that the diesel particulate filter, which helps reduce emissions, is becoming clogged. To resolve this, drive the vehicle at a sustained speed on a dual carriageway or motorway to allow the filter to regenerate and clear itself. If the light remains on, a professional cleaning or replacement of the filter may be necessary.

Green and blue warning lights

Indicator and hazard warning lights

These lights, represented by green arrows, flash when the indicators or hazard lights are activated. They are purely informational and do not indicate a fault. Ensure that these lights function correctly to signal your intentions to other road users.

High beam light

The high beam light, usually a blue icon of a headlamp with rays, illuminates when the high beams are turned on. This light serves as a reminder to switch back to low beams when appropriate to avoid dazzling other drivers.

Additional advice

Refer to your manual: your Volkswagen T5's owner's manual is packed with helpful information, including a detailed list of warning lights and what they mean. Keep it handy for quick reference whenever a new light appears.

Consider an OBD-II scanner: investing in an OBD-II scanner can provide deeper insights into specific warning lights. This tool can help you troubleshoot minor issues before heading to the mechanic, potentially saving you time and money.

Don't ignore warning lights: ignoring warning lights on your dashboard can lead to bigger problems down the line. Address them promptly to keep your Volkswagen T5 running smoothly and avoid costly repairs.

Remember: this list covers common warning lights, but your Volkswagen T5's lights may vary based on their model year and trim level.

Trust the lights

Understanding your Volkswagen T5's warning lights gives you the knowledge you need to take the right action when they appear. Regularly checking your dashboard and addressing issues promptly ensures safe and reliable driving. 

If you're ever unsure about a warning light, consult your owner's manual or a qualified mechanic for assistance. With vigilance and proactive maintenance, your Volkswagen T5 will serve you well for years to come.
