Red Dashboard Warning Lights: Meanings for Audi, BMW, Škoda

Published

Short answer: Red warning lights flag the most urgent faults, and their meaning varies by brand. On Audi and Škoda cars, the red triangle points to an urgent message you should read at once. Red oil pressure warnings on Audi and BMW mean stop and switch off. A coolant overheating warning on Audi, BMW and Škoda means stop and do not drive on.[1, 2, 3, 4, 5, 6, 7]

What does the red triangle mean?

On Audi cars, the Central warning (red triangle) draws attention to an urgent message shown with it. On its own it does not identify a component. Read the full message or second symbol in the driver display straight away and follow its instruction.[1]

On Škoda cars, the red triangle is the central warning for a serious hazard. It may light alone or together with another red light, and the instrument cluster normally shows a message about the fault. Read the message and follow the instruction for the light that accompanies it.[2]

On BMW cars, the Check owner's handbook symbol (a book with an i) in orange or red is a fault or hazard warning to take seriously. Look up the accompanying message in the owner's handbook to find out how serious it is. For any other central warning light on a BMW, check your own manual.[8]

Red oil and coolant warnings: when to stop the engine

Oil and coolant lights are among the most urgent red warnings, but the instructions differ by brand. Some point to low pressure or overheating, others to a low level that you can check yourself.[3, 9, 10, 7]

  • Engine oil level / oil pressure warning symbolAudi, red Engine oil level / oil pressure warning: oil pressure may be too low to lubricate the engine, even if the oil level reads fine. Stop safely, switch off and arrange recovery. Do not restart to get an electronic oil reading, and do not drive on after adding oil.[3]
  • Engine oil sensor warning symbolBMW, Engine oil sensor warning in orange or red: the sensor reports dangerously low oil pressure. Stop the engine as soon as it is safe and have the car checked before driving on.[4]
  • Engine oil level / oil pressure warning symbolBMW, oil can symbol in orange or red: the oil is low. Check the level and top up, or have the car checked.[11]
  • Engine oil level / oil pressure warning symbolŠkoda, oil can symbol flashing with the red triangle: engine oil pressure is too low. Check the engine oil level.[9]
  • Engine oil sensor warning symbolŠkoda, Engine oil sensor warning with the red triangle and a top-up message: the oil level is too low. Check the level and top up if required.[10]
  • Coolant temperature warning (red) symbolAudi, red Coolant temperature warning: coolant may be low, the engine may be overheating, or the reading may be faulty. Follow the stop instruction and switch off for overheating or fast coolant loss. Never open the coolant cap while the engine is hot, and a full-looking reservoir or normal gauge does not cancel the warning.[6]
  • Coolant temperature warning (red) symbolBMW, thermometer-in-water symbol in orange or red: the engine is in danger of overheating, which can cause severe engine damage. Stop safely and have the cooling system checked before driving on.[5]
  • Coolant temperature warning (red) symbolŠkoda, red coolant light with the red triangle: with an overheating message the engine is too hot, so do not continue driving. With a coolant-check message the level is too low, so check the coolant level.[7]

Red brake and ABS warnings

  • Brake warning (BRAKE) symbolBMW, Brake warning (BRAKE) in orange or red: the braking system needs to be inspected as soon as possible.[12]
  • Brake pad wear warning symbolBMW, Brake pad wear warning in orange or red: the pads are probably worn and due for replacement. Book a brake service.[13]
  • Brake overheating (red) symbolAudi, Brake overheating (red): the discs and pads are overheating. Pull over as soon as you safely can and let them cool, because the brake fluid can boil and braking pressure can be lost.[14]
  • ABS warning symbolAudi, ABS warning with the red brake warning, or with a pedal that feels different: stop safely and get assistance.[15]
  • ABS warning symbolŠkoda, ABS warning with the red brake light: there is a fault in the brake system and ABS. Do not continue driving.[16]

Red battery, engine and powertrain lights

  • Charging / battery warning symbolBMW, Charging / battery warning in orange or red: the battery is not being charged properly. Have the charging system checked by a workshop soon.[17]
  • Charging / battery warning symbolŠkoda, red battery light with a 48V network message on mild-hybrid cars, or a message that the 12V battery is not charging: park safely, switch off the engine and ignition, and get help from a specialist garage.[18]
  • Charging / battery warning symbolŠkoda, red battery light together with the red coolant light and the red triangle: this indicates an engine fault. Stop and do not continue driving.[18]
  • Engine management warning symbolBMW, Engine management warning in orange or red: a solid engine symbol can mean anything from a loose fuel cap to a severe engine problem. Check the fuel cap and have the engine diagnosed.[19]
  • Emissions warning symbolBMW, Emissions warning (an outlined, not filled-in, engine) in orange or red: an emissions problem. Have the car checked.[20]
  • Drive power / powertrain warning symbolBMW, Drive power / powertrain warning in orange or red: a powertrain problem that needs immediate attention. Stop safely and get help.[21]
  • Engine start system fault (red) symbolAudi, Engine start system fault (red): the electronic start system has a fault. If the engine is running, do not switch it off; drive straight to a workshop and contact it right away.[22]

Red collision and driver assistance alerts

  • Audi pre sense collision warning (red) symbolAudi, Audi pre sense collision warning (red): a collision hazard has been detected. The system warns with visual, sound and haptic signals and can brake partly or fully, tighten the seat belts, close the windows and sunroof and switch on the hazard lights. React immediately.[23]
  • Audi pre sense warning symbolAudi pre sense never takes over the driver's responsibility, and a red collision alert needs an immediate reaction from the driver.[24]
  • Distance warning (red) symbolAudi, Distance warning (red): a vehicle or obstacle ahead is too close or being approached too quickly. Brake and increase the gap. With an exclamation mark it can point to a system fault, often from weather or a dirty sensor, so drive with extra care.[25]
  • Front Assist collision warning (red) symbolŠkoda, red Front Assist collision warning: there is a risk of collision. If the driver does not react, the car brakes automatically.[26]
  • Active Cruise Control warning symbolBMW, Active Cruise Control warning in orange or red: take over. Pay closer attention to the road or put your hands back on the steering wheel.[27]
  • Dynamic Stability Control (DSC) symbolBMW, Dynamic Stability Control (DSC) symbol in orange or red: stability control is working hard to keep traction. Drive carefully.[28]

Airbag, AdBlue, DPF and other red lights

  • Airbag warning symbolBMW, Airbag warning in orange or red: the airbags may not deploy properly in an accident. Have the system checked as soon as possible.[29]
  • Airbag / restraint system warning (amber) symbolAudi, airbag or restraint system warning: usually amber, but on some models the same symbol lights red. Have it inspected promptly with suitable diagnostic equipment, and do not unplug seat or airbag wiring to make the light go out.[30, 31]
  • AdBlue warning symbolAudi, AdBlue warning: red no-start messages need the exact procedure for the vehicle. Act before any no-restart countdown reaches zero, and note that a refill does not fix dosing or sensor faults.[32]
  • Diesel particulate filter (DPF) warning symbolBMW, Diesel particulate filter (DPF) warning in orange or red: the filter needs attention. Have it serviced.[33]
  • Auto Start/Stop fault symbolBMW, Auto Start/Stop fault in orange or red: the Stop/Start system is malfunctioning and needs attention at a workshop.[34]

If a red light on your car is not listed here, or your brand is not covered, check your own owner's manual for its exact meaning.

Frequently asked questions

Can I keep driving with a red warning light on?
It depends on the light and the brand. Red oil pressure warnings on Audi and BMW, coolant overheating warnings on Audi, BMW and Škoda, and the BMW powertrain warning all call for a safe stop. The exception is the red engine start system fault on Audi: if the engine is running, do not switch it off and drive straight to a workshop.[3, 4, 5, 6, 7, 21, 22]
What does it mean when the ABS light and red brake light come on together?
On Škoda cars, this means a fault in the brake system and ABS, and you should not continue driving. On Audi cars, if the red brake warning comes on with the ABS light, or the pedal feels different, stop safely and get assistance.[15, 16]
Why is the red triangle on with another light on my Škoda?
The red triangle is Škoda's central warning for a serious hazard. It may light alone or together with another red light. Read the message in the instrument cluster and follow the instruction for the accompanying light.[2]
Is a red battery light serious on a Škoda?
Yes. With a 12V not-charging or 48V network message, park safely, switch off the engine and ignition, and get help from a specialist garage. With the red coolant light and red triangle, it indicates an engine fault: stop and do not continue driving.[18]
Why did the snowflake on my Audi dashboard turn red?
On Audi cars, the frost warning may turn red at freezing point. It means roads may be icy, so drive with care.[35]
