The tire pressure and traction control systems in your Volkswagen are closely linked\u2014and sometimes, one light can trigger another to turn on. Here\u2019s why that happens.<\/p>\n\n\n\n
Whether you drive a Jetta or Beetle<\/a>, all Volkswagen warning lights are more or less the same\u2014and it\u2019s important to know what they mean, and when they\u2019re a cause to be concerned. In this article, we\u2019ll be covering the meaning behind your car\u2019s ABS, traction control, and tire pressure lights.<\/p>\n\n\n\n Learn more<\/strong>: How to lower Volkswagen insurance costs<\/a><\/p>\n\n\n\n If you notice the traction control light (TCS) turn on in your Volkswagen vehicle, it could mean one of two things: either your car\u2019s ABS traction control system is functioning as intended, or there\u2019s a serious problem. As you can imagine, that\u2019s why this light is one of the most confusing dashboard warnings out there.<\/p>\n\n\n\n Basically, your ABS traction control light isn\u2019t always a warning light. Sometimes, it\u2019s activated simply when the system is functioning as intended\u2014which is when it\u2019s maintaining traction between your tires and the road surface. In wet or slippery conditions, you may notice this is happening if the TCS light flashes on and back off, or stays illuminated only for a brief period of time.<\/p>\n\n\n\n When this happens, the TCS light may be accompanied by other lights\u2014including your ABS and tire pressure lights\u2014before turning back off. If, on the other hand, the TCS light turns on and stays illuminated, it could be an indicator that there\u2019s actually a problem.<\/p>\n\n\n\n Your Volkswagen\u2019s ABS traction control system uses sensors in the wheels to monitor tire speed and grip\u2014and, if there\u2019s a loss of traction, to trigger the car\u2019s traction control module <\/strong>to activate your anti-lock braking system. But if any of the components involved in this system (from the sensors to your anti-lock brakes) malfunctions, your car\u2019s TCS light may come on, often alongside the ABS and tire pressure lights. Low tire pressure can also trigger your TCS light to come on.<\/p>\n\n\n\n Below, we take a closer look at some of the most common reasons your Volkswagen\u2019s TCS light turns on.<\/p>\n\n\n\n Learn more<\/strong>: Are Volkswagens expensive to maintain?<\/a><\/p>\n\n\n\n As we\u2019ve mentioned, your traction control light typically turns on during normal operation\u2014that is, whenever you\u2019re driving in conditions without much traction.<\/p>\n\n\n\n If your traction control system is working to maintain your tire\u2019s grip on the road surface (as it should in slippery conditions) then the light may flash on and back off, along with the warning lights of other closely related systems, like your anti-lock braking system and tire pressure monitoring system.<\/p>\n\n\n\n If your TCS light doesn\u2019t<\/em> turn back off, there\u2019s a chance you\u2019re dealing with a different kind of problem\u2014and faulty wheel speed sensors <\/strong>are one of the most common reasons your traction control system malfunctions.<\/p>\n\n\n\n Given that the wheel sensors are mounted to your VW\u2019s wheels, they\u2019re subject to all the rough and tumble conditions that we drive through\u2014and eventually, they wear out. If your traction control light won\u2019t turn off, bring the vehicle to a repair shop to check the wheel speed sensors. You can also use an OBD-II scan tool to check for trouble codes associated with these sensors.<\/p>\n\n\n\n Another common reason your Volkswagen TCS light won\u2019t turn off is related to low tire pressure <\/strong>in your wheels. Your wheel sensors can interpret low tire pressure as a traction problem, causing the TCS light to turn on. A bad tire pressure monitoring system (TPMS) could also trigger this issue.<\/p>\n\n\n\n
