A warning light that goes off is not a good omen. You may think that this is quite simply a concern related to sensors . Nevertheless, it is essential to pay attention to it. How does an ABS work? Why is the light on? What to do? We will answer all of these questions so that you can drive the Volkswagen 411 in complete safety.Volkswagen-411 warning light

What is ABS on a Volkswagen 411

ABS stands for Anti Blocking System . It is a device which offers the possibility of improving the braking system, in particular for intensive braking. Before the creation of ABS, the brake pedal was directly connected to the pads. When you pressed, the pads closed on the discs. The downside with this system is that there can be a risk of slippage. Thanks to sensors, the ABS calculated braking. Instead of pressing on the discs, the pressure will vary several times per second, thus preventing a blocking complete the tires of the Volkswagen 411. No slippage, and braking is much more efficient.

Volkswagen 411: why the ABS warning light is on

When the ABS warning light is on, your Volkswagen 411 is sure to have a problem. As with all other indicator lights, it is rather common that it simply concerns an electrical connection problem. However, it is better to be sure.

False contact

Reassemble the cables of the ABS sensors of your Volkswagen 411 and take the electrical intensity using a multimeter . If ever one of them does not have the same value as the others, there is an electrical problem. Go back up the line, if you find a bad connection it will have to be fixed. When a wire is damaged, it will have to be replaced.

A sensor problem

This naturally remains a rather recurring concern for a Volkswagen 411. The sounder may emit an incorrect message. Then, it will suffice to replace the sounder in question. It is possible to control the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of your Volkswagen 411 works using a system hydraulic , which manages the pressure of the brake pads. When this system is damaged, the replacement of the ABS unit is often necessary. When it is a concern of the block, it is often felt by braking.

Conclusion

The ABS warning light which remains on can come from quite different reasons. Either a pollster's concern, a false contact. If ever the ABS unit is faulty, it will certainly have to be changed. And this intervention is rather expensive, for a Volkswagen 411 or for each type of automobile. It is essential not to neglect an ABS warning light, for understandable safety reasons.
