An illuminated indicator light is by no means a good sign. One can think that it is simply a problem coming from sensors . However, it is important to pay attention to it. What is ABS used for? Why is the indicator light on? How to do? We will answer all of these questions, so you can drive and drive your Volkswagen Golf 7 Sw with confidence.
What is ABS on a Volkswagen Golf 7 Sw
ABS stands for Anti Blocking System . It is a system which will make it possible to improve the braking system, in particular during sustained braking. Before the creation of ABS, the brake pedal was directly linked to the pads. As soon as you pressed, the pads closed on the discs. The trouble with this system is that there can be a risk of skating. With the help of sensors, ABS calculated the braking system. Instead of maintaining the discs, the pressure will oscillate a certain number of times in a very short time, thus making it possible to prevent a blocking complete wheels of the Volkswagen Golf 7 Sw. Not a single slip, and braking becomes much more efficient.
Volkswagen Golf 7 Sw: why the ABS warning light is on
When the ABS warning light is on, there is no question that the Volkswagen Golf 7 Sw has a problem. As with all the other indicator lights, it is rather common that it simply concerns a contact problem. However, it's better to be sure.
False contact
Wind the ABS sensor lines of the Volkswagen Golf 7 Sw and read the electrical current with a multimeter . In the event that one of them does not hold the same value as the others, it is because there is an electrical problem. Follow the wiring, if you discover a connection fault it will have to be fixed. If a wire is ever damaged, it must be replaced.
A sensor problem
This is of course a fairly common problem on a Volkswagen Golf 7 Sw. The sensor may be sending the wrong message. In this specific case, it will suffice to replace the sounder in question. You will be able to test the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of the Volkswagen Golf 7 Sw operates using a mechanism hydraulic , which will manage the pressure of the brake pads. In the event that this mechanism is deficient, replacement of the ABS block is generally essential. When this remains a problem with the block, you can usually feel it when you brake.
Conclusion
The ABS warning light that remains on can come from quite distinct reasons. Either a sonar problem, an electrical fault. Assumed that the ABS unit is not functional, it will probably have to be changed. And this intervention happens to be relatively expensive, on a Volkswagen Golf 7 Sw or on any car model. It is important not to neglect an ABS witness, for obvious security reasons. Leave us a comment if this specific ABS warning light article was useful. Enjoy the road!
