Post by Andrew J » Wed Apr 10, 2024 1:28 pm

Afyer pulling away from a stop today there was juddering when pressing the brakes then dashboard lit up like a Christmas tree. Turned the car off then on and thrblights went away thrn came back. Car brakes fine now but the lights are still on. I've plugged my code reader in but nothing comes up. Any ideas folks?

ABS sensor normally. Should show a code though telling you which one it is. Mine went last week!

The code reader is a cheapy ebay jobby connected to Torque lite so I don't think it's that good. I'm getting the codes read on Friday by a friend who works for the AA so he should be able to tell me what the codes are. I've just seen some posts about this so hopefully it is just a sensor.

OK, from experience................ and happy to be corrected by other people's experiences:

Usually all four would suggest one of the wheel sensors.
Minus the abs light tends to be the yaw sensor under the seat.
I am lucky so far, not had one of the two sensors on the brake unit fail, so not sure what combination of lights that throws up.

If your speedo still worked then it's not the left rear sensor.

Always happy to help if I can.

If the forum helped you, why not help the forum back. Thats the Z4 way! :thumbsup:

I had this exact set of 4 lights last week. Code reader said front left wheel speed sensor. I replaced all four and cleaned up the reluctor rings. Cleared codes and all good :thumbsup:

DSC sensor throws the yellow handbrake light (obvs red if the handbrake is on!) and the ABS triangle.

Front left abs sensor confirmed by friend with AA computer. Any recommendations on a brand from autodoc? Lots to chose from on there.
