    ABS wheel speed sensor fault - sensor and bearing changed twice

    Thanks ScottyP45 you’re right I was being dumb and measuring it wrong! I’ll try again and measure correctly I thought I had ruled out the abs control unit but that’s because I measured the signal wrong. So if I see a signal on the scope this time then that confirms it’s the abs control unit...

    ABS wheel speed sensor fault - sensor and bearing changed twice

    Thanks I saw that the other day so I lifted up the rear seats but didn’t find anything. The car in his video is not a 5 door A3.

    ABS wheel speed sensor fault - sensor and bearing changed twice

    I had a 1 meter breaker bar to do the extra 180 degrees but because the bolts were those horrible torx type I struggled to get 90 degrees. I’ve replaced the stretch bolts on the front wheels (when replacing the cv boots) which used the 12 spline type bolts and I managed to do 180 degrees on...

    ABS wheel speed sensor fault - sensor and bearing changed twice

    I did think of trying this but I don’t know where the connector further up stream is? I can see the wiring go from the sensor into the wheel arch liner (behind a plastic fuel pipe as it’s on the same side as the fuel filler) but I don’t know the route it takes to get to the abs module?

    ABS wheel speed sensor fault - sensor and bearing changed twice

    No the scope is on DC coupling, it’s showing a voltage level of 12V DC but no pulses when spinning the wheel. The sensors are 2-wire current sensors (not 3-wire voltage sensors). There is usually a pull down resistor in the control unit to convert the current to a voltage which then goes to a...

    ABS wheel speed sensor fault - sensor and bearing changed twice

    Six months ago the ABS warning light appeared on the dash of my Audi A3 1.8 TFSi (2007, 8P). Using VAGCOM I found that the issue was with the rear right wheel speed. I changed the sensor but this did not fix the problem, so I changed the wheel bearing (which has the magnetic ring on it) and...

    A3 8P bonnet won’t open

    Thanks Will you have saved my bacon (almost) ! Unfortunately I destroyed the plastic lift catch and don't know how to get around this, any ideas ? Im not bothered about the mess I've made to the car, its a piece of sh1t (never buying Audi or VW again) and Im sick of fixing it all the time! I...
