Volkswagen Dashboard Warning Lights: What Each Symbol Means

Published

Short answer: Volkswagen warning lights use two urgency levels. The red central warning triangle is a priority 1 warning: do not drive on, stop when safe and get expert help. The yellow triangle is a priority 2 warning: have the fault checked soon by a workshop. Symbols such as the oil, battery, brake and ABS lights show which system has the fault.[1, 2, 3, 4, 5, 6]

How do red and yellow warnings work on a Volkswagen?

On Volkswagen cars, the red central warning triangle is a priority 1 warning. It lights or flashes, sometimes with a chime, other symbols and a text message. Do not drive on: stop when safe, check the fault shown and get expert help as soon as possible. While this warning is active, the instrument cluster menus cannot be opened.[2]

The yellow central warning triangle is a priority 2 warning. It lights or flashes, sometimes with a chime or other symbols. Check the fault soon and have it checked by a workshop, because low fluid levels or faults can damage the car.[1]

Red Volkswagen warning lights and what to do

Several red symbols on a Volkswagen dashboard tell you not to drive on. Each one points to a specific system, so read the message on the display as well.[4, 7, 3, 8, 5, 9]

  • Charging / battery warning symbolCharging / battery warning: lit red with a message, it means the 12-volt electrical system may fail. Do not drive on: stop safely, switch off unnecessary consumers and the ignition, and get expert help. The start/stop system does not work while it is lit.[4]
  • Coolant temperature warning (red) symbolCoolant temperature warning: lit with the red central warning and a message, or flashing red, it means the coolant level is wrong or the coolant system has a fault. Do not drive on: stop, switch off the engine, let it cool and check the coolant level. Get expert help if the level is correct but the light stays on.[7]
  • Engine oil level / oil pressure warning symbolEngine oil pressure warning (oil can): flashing red means engine oil pressure is too low. Do not drive on and do not leave the engine running. If it keeps flashing although the oil level is correct, get expert help.[3]
  • Engine oil sensor warning symbolEngine oil sensor warning: flashing red means the engine oil level is too low. Do not drive on: switch off the engine and check the oil level. If it stays on although the level is correct, do not drive or run the engine and get expert help.[8]
  • Parking brake warning symbolBrake warning (the brake (!) symbol): lit red when there is a brake system fault or the brake fluid level is too low. Do not drive on; check the brake fluid and get expert help.[5]
  • Steering fault (red) symbolSteering fault: red, lit or flashing. Lit means the electromechanical steering has failed and steering may feel heavy; flashing means the steering column cannot be unlocked. Do not drive on and get expert help.[9]

Not every red light is a do-not-drive-on warning. The red Seat belt reminder is a prompt to buckle up: it lights red, and flashes on the display, when the driver or front passenger has not fastened the belt with the ignition on. At higher speed a chime sounds too, and it goes out only when all occupants are belted.[10]

On some instrument clusters, an unfastened rear belt makes the seat symbols flash while driving.[10]

Red AdBlue and SCR warnings: when the engine won't restart

The red AdBlue level low bottle appears when the AdBlue level is too low and the yellow warning was ignored. A message asks you to refill AdBlue, and the engine cannot be restarted. Park and add at least the minimum quantity of AdBlue.[11]

The red SCR system fault symbol (AdBlue bottle and spanner) is the red stage of an exhaust aftertreatment fault or non-standard AdBlue, shown when the yellow warning was ignored. A message says the engine start is disabled, so once switched off, the engine cannot be restarted. Drive straight to a workshop without switching the engine off and have the system checked.[12]

Yellow Volkswagen warning lights: get them checked

  • ABS warning symbolABS warning: lit yellow, ABS has failed or has a fault. The brakes still work, but without ABS, so drive carefully and have it checked.[6]
  • Airbag / belt tensioner fault (amber seated occupant) symbolAirbag / belt tensioner fault (amber seated occupant): lit continuously yellow means a fault in the airbag or belt tensioner system; have it checked straight away. It also lights briefly at ignition on as a function check.[13]
  • Passenger airbag off symbolPassenger airbag off: lit yellow while the front passenger front airbag is switched off with the key switch.[14]
  • Brake pad wear warning symbolBrake pad wear warning: lights yellow when the brake pads are worn. Go to a workshop straight away and have all brake pads checked and replaced if necessary.[15]
  • Electronic parking brake fault (amber) symbolElectronic parking brake fault: the yellow central warning light comes on and the parking brake button indicator lights yellow. Have it checked by a workshop.[16]
  • ESC / TCS (amber solid car with skid marks) symbolESC / TCS (car with skid marks): flashing yellow means stability control or traction control is intervening. Lit continuously means an ESC fault; if it stays on, go to a workshop.[17]
  • Headlamp fault warning symbolHeadlamp fault warning: lights yellow when exterior vehicle lighting has failed fully or partly. Check the bulbs and lights.[18]
  • Water in fuel filter warning symbolWater in fuel filter warning: lit yellow means water in the diesel fuel. Slow down at once and drive to a workshop; if it lights straight after refueling, do not drive on, switch off the engine and get expert help immediately.[19]

Driver assistance warnings that need instant action

  • Front Assist collision warning, car between lanes (red) symbolFront Assist collision warning (red car between lanes): warns of an acute risk of collision with a red light and a chime. Brake or steer round the obstacle at once; depending on speed, the car may also brake automatically without an earlier warning stage.[20]
  • Rear Traffic Alert obstacle (red) symbolRear Traffic Alert (red): the system has detected crossing traffic behind the car while you reverse out of a space or maneuver, and it may brake. Keep watching the surroundings, because the system only works within its limits.[21]
  • Take over steering now (red hands on wheel) symbolTake over steering now (red hands on wheel): Travel Assist or Emergency Assist shows it with a message when you must take hold of the steering wheel and steer immediately. It follows the white request to take over steering if that was ignored.[22]

What does it mean when two lights come on together?

  • ABS warning symbolABS light plus the red brake warning: ABS control may have failed completely, on top of the brake fault or low brake fluid the brake light signals.[6, 5]
  • ESC / TCS (amber solid car with skid marks) symbolESC light plus the brake warning: ABS control may have failed too.[17]
  • Passenger airbag off symbolPassenger airbag off plus the airbag warning: there may be a fault in the airbag system. The same applies if the passenger airbag off light does not come on while the airbag is switched off.[14]
  • Airbag / belt tensioner fault (amber seated occupant) symbolAirbag light on for about 4 seconds after ignition, then flashing for about 12 seconds: the airbag or belt tensioner system has been switched off with a diagnostic tool.[13]

These meanings come from the Volkswagen Tiguan owner's manual (11.2021). If a light on your Volkswagen is not listed here, or behaves differently, check the owner's manual for your own model.[6, 1, 2]

Frequently asked questions

Can I drive with the ABS light on in my Volkswagen?
When the ABS light is lit yellow, the brakes still work but without ABS, so drive carefully and have it checked. If the brake warning light is also on, ABS control may have failed completely, and the red brake warning tells you not to drive on.[6, 5]
What does a flashing red oil light mean on a VW?
Depending on the symbol, it means engine oil pressure is too low or the engine oil level is too low. In both cases, do not drive on; switch off the engine, check the oil level, and get expert help if the light continues although the level is correct.[3, 8]
Why won't my Volkswagen restart after an AdBlue warning?
The red AdBlue and SCR warnings appear after a yellow warning was ignored, and they disable the engine start. For low AdBlue, add at least the minimum quantity; for an SCR fault, drive straight to a workshop without switching the engine off.[11, 12]
What does the yellow triangle mean on a VW dashboard?
The yellow triangle is a priority 2 central warning. Check the fault soon and have it checked by a workshop, because low fluid levels or faults can damage the car.[1]
Why does the airbag light come on when I start my Volkswagen?
It lights briefly at ignition on as a function check. If it stays lit yellow, there is a fault in the airbag or belt tensioner system and it should be checked straight away.[13]
