brake pads sensor

The road conditions are probably more the reason the nearside fails in the UK, bigger pot holes near the kerb, more vibration through the struts and wiring vibrating , may also be the routing and extra weight of the wear sensor pair of cables. As said check the existing wiring at the sensors then you know which 4 to trace back.
 
For what it's worth..

Yes, I know that lots of people have done the solder method but having got the proper repair kit I thought I would try and do a proper job.
I am with you on that and in my case I am forced into it. I tried connecting new to old in the engine compartment and the pad sensor is still present on the dash; I must have a discontinuity higher up. I have to say I was shocked at the corrosion on the pad core wires in the engine compartment so I am not surprised. It must be the nature of the pad circuit as the ABS cores are pristine.

I've always imagined that the ABS wires on the front left and right are equally likely to break due to the stresses from the steering, but I don't recall anyone on the forum getting that problem.
Yes I agree, I have seen the odd post about a ABS loom fault at the front but it is rare and generally not a problem, always the pad warning loom. As mentioned I suspect for some reason corrosion in the warning loom and/or the exposed position of the connectors and previous abuse when changing discs/pads.

..... for the front right the same kit is used and the brake sensor plug cut off.

Nothing so crude, it will have a different part number and have a different length.

I have chased this problem for a while now, over the years. I started with shorting the wires down by the plug which was fine for a few years but just recently it came back with a vengence. I tried further up, I tried on the multiplug by the door jam and finally gave up have done it on the back of the instrument cluster. Bridge pins 2 & 24 on the blue plug. Job done.
 
i try all solution for this brake pads warning light but with no success, can somebody confirm that by making a bridge like AndyP suggested will put the message to off.

Morning,

You can also creat the circuit at the A pillar, much easier and saves removing the instrument cluster.

Kind regards,

Tom
 
what color or number are the wires in the A pillar area ?
It varies depending on the model and age of your A2. Furthermore, the Audi documentation for the A-pillar connectors is riddled with inaccuracies, so it’s important to verify the purpose of any wire before making modifications.

Cheers,

Tom

Hello there,

To further helpfully assist, can you confirm that the vehicle you propose this to be completed on is as per your profile:

2000 1.4 AUA

Kind regards,

Tom
 
While I fully understand you want to "short out" the pad wear inside the car. I feel you would be better getting the system working correctly by replacing the complete loom. If the damage is due to corrosion or physical damage such as tyre rubbing then the second and more important part of that loom - the ABS sensor wiring may also be damaged.

As @timmus has said the wiring diagram was not given to the electricians when they wired the car and frequently do not match the wiring you find. If you are not confident have a professional complete this for you.
 
Good Afternoon,

As said the best course of action is to replace the loom in some form.

However if you wish to bypass the pad warning at base of the A-pillar from memory you need to focus on the red⁕ 17 pin connector and the red⁕ wire at pin 13. (⁕= normally in our part of the world) . To my eyes the red wire is a long way to to being a pink wire. you can see it here disconnected (you have no need to disconnect).

To check short the pin 13 to earth and the dash warning should go away. To make this permanent I would unwrap (& rewrap when finished) the loom 10cm and cut the red wire. Strip the red tail sufficient to attach a ring connector and then connect to the main earthing point also shown in the picture.

Evening @Valentin,

Andy @Andrew has provided a great answer which will help you get the warn pads illumination to extinguish. As has been said throughout this thread though, best course of action is to repair so you can be notified when the pads do actually become worn.

Andy’s helpfulness above is spot on and very similar to what I done on Project OEM as a temporary measure until I got a replacement loom. The only difference is that I didn’t cut any wires, I simply removed Pin 13 from the Red connector and soldered an additional wire to it, which was long enough to reach the earthing point at the base of the A pillar (shorting/creating the circuit) then placed the pin back in the connector. Once the correct repair was complete with a replacement loom I desoldered the additional wire and everything was back to how it should be as per a factory arrangement.

A very quick temporary solution which doesn’t involve removing the instrument cluster.

Kind regards,

Tom
 
thank you all for various solution detailed here, the car is 200 km from me (is my sister in law car) and when is possible I will give it a go.
