00:00What would cause your Audi traction control light to stay on?
00:06Traction control light or TCL of your car if on, it is a sign of trouble.
00:11There are countless reasons why the TCL of a car may come on.
00:17Here, we will discuss some of them in detail.
00:21But, before we proceed, let's have a brief conversion about the traction control system.
00:27Traction control system or TCS, what does it do?
00:33TCS plays an important role in your vehicle's stability control system.
00:37It ensures that your car is not losing traction on a slippery road surface.
00:43It does that by preventing wheels from overspinning.
00:48And, to make that happen, it takes the help of the following component.
00:52A hydraulic controller, an electronic control unit, wheel speed sensors, wires, connectors.
01:01If your car's TCS stops working, TCL will light up to warn you about the problem.
01:07Traction control light reasons why it may come on.
01:12Wheel speed sensors are faulty.
01:14If your Audi's TCL is on, it is usually because your wheel speed sensors are faulty.
01:23To turn off the TCL, you have to identify and replace the defective sensors.
01:29Electronic control unit, AQ, is defective.
01:34AQ is programmed to regulate different aspects of TCS operation in your car.
01:39If it fails due to a programming error or for any other reason, TCL will be triggered.
01:46ABS may be failing.
01:51Abs and TCS are two sides of the same coin.
01:56They may seem different from the outside, but they are very closely related.
02:00If one goes down, the other will follow suit.
02:08If ABS goes bad, the TCL will come on.
02:12Failing braking system
02:14It has also been found that problems in the braking system of a car can trigger TCL.
02:24Sum up
02:24Lit up TCL warns you that there is something wrong with your car's TCS.
02:33Get to the bottom of the problem before it's too late.
