    Hi, looking for some guidance here, I ve had the abs asc lights on and off in the last few months and typically they choose to pop on during mot test. Ok I think I have to sort this, I bought a C110 and adaptor and its telling me both front sensors and pump motor.

    I've tried removing one of the sensors but its stuck fast.

    Does anyone have any tips on how to remove them?

    Also the pump motor code is it possible this is showing because the system has been disabled by the ECU because of the sensors?

    Thanks in advance
    Garry

    The sensors rarely come out with ease. It's usuall you have to break and drill them out. Modern ABS sensors aren't a tight fit in they have plastic "fins" to keep them centralised but don't corrode into the hub.

    I had to beat mine out the last time I changed one. Once it was out I cleaned the hole out with a Dremel with a flexi extension and mini grinding bit. Worked great.

    Personally @Greybloke I'd do the sensors first as these can sometimes throw up the ABS module error code. If the problem is still there afterwards then do the ABS module. I had a similar issue with my black zed but the garage diagnostics said right side sensor and ABS module. I bought a pair of sensors from an ebay seller in Germany for around £20 the pair. Anyway, I changed the sensor and went for a ride and the lights went out after only about 100yds. I still haven't needed to touch the module. I know some members have had issues with the module but I'd do the cheaper things first. Good luck.

    Going back to your first post @Greybloke my sensor was stuck so had to beat it out. I tried to prize it out but it wouldn't budge. So, remove the wheel, brake caliper and disc so that you can get to the bolts holding the back plate to the hub. Remove the bolts so that the plate swivels on the hub. If you rotate it you will be able to see the bottom end of the sensor. Find an appropriate size drift and just beat it out. Once it's out you can clean the hole out. I used a Dremel with a flexi hose with an abrasive bit. It doesn't take long to do once you get onto it.
    I meant to do a "how to" on this but I'm sh*** at remembering to take photos. That comes with being old =))
