Hi All

I have an A2 2001 1.4 petrol. Recently my husband replaced the nearside front left wheel bearing since then the abs fault shows on the car. We have replaced the speed sensor but still no change. Have used a neighbours code checking machine and its showing No faults??? On start up only the abs light stays on and when you drive forward the car starts beeping loudly and the warning triangle comes on. Any ideas what could be wrong???
