The ABS (anti lock braking system) requires wheel speed sensors to operate. When one of the wheel speed sensors fails you will get an ABS warning light appear and it will not disappear until you have fixed the problem - in this case replaced the faulty sensor(s).

It is not a DIY job so do not attempt to do it yourself when you do not know what you are doing.

    Many thanx for your reply. I have fixed faulty VSS on different makes before. Advantage then was it was specific tasks that I was asked to perform with a someone else having diagnosed the fault. Whereas in this case I just need to be sure of the meaning of P0500. and speed sensor "A". If anyone knows please update. Oh it is something I will do myself no doubt. if I manage I will post images and information on how to fix the problem, I have been taking images and feel am near to fixing this, please heeeeeeellllllllllpppppp..

They are not the sensors you want. The car uses the abs wheel sensors for vehicle speed. Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. .

SOURCE: ABS Fault? Renault Megane

Hi Liz, I am in exacty the same position as you although I just had the new abs pump fitted and I still have the same problems??? I am going crazy with this, my garage's diagnostic machine won't commuicate with my car and my speedo is not working? My mechanic reckons the abs memory is stuck in a loop and that is why the lights ain't going out, but without a diagnostic I dont know, I guess I will have to take it to a dealership to be ripped off!!!!

SOURCE: ABS and service light reset after brake change

the ABS light resets itself every time the key is turned off and on, it is self testing and will only turn the light on when there is a problem in the ABS system, worn out brakes don't cause the ABS to come on, if the light is on the system has a fault present and it must be tested with a factory system scanner to determine the source of the fault or at least the area that is causing the problem, that can be one of the four wheeel speed sensors, a defective ABS hydraulic control unit and sop on.

A P0500 code is a diagnostic trouble code (DTC) titled "Vehicle Speed Sensor (VSS) Malfunction." This code is triggered when the vehicle's Powertrain Control Module (PCM) or Engine Control Module (ECM) detects inaccurate speed readings or lack of a signal from the Vehicle Speed Sensor (VSS).

P0500 is a problem with the vehicle speed sensor. The ABS light on is also caused by this P0500 code.

Get the vehicle speed sensor checked, see if the wiring is causing the problem (frayed). If there is no problem with wiring, try replacing the vehicle speed sensor.

T reg renault megane.ABS light and serv light on dashboard are staying on,are the 2 linked or is it 2 seperate problems.can i still drive the car with both dashboard lights on.

All the computers on the car are linked together. The ABS can trigger the service light on some applications, ie speed sensors. You can still drive, but you wont have ABS, meaning if you brake hard enough or in gravel the tires can lock up and skid.
