ABS issues

Hello. I'm having a few issues. A few weeks ago out of the blue 3 lights popped up on the dash. ABS, t/c esp, tyre pressure warning. A scan revealed rear left wheel speed sensor fault. So, fitted a new abs sensor but while I was fitting it I Noticed the magnet looked a bit rough. So put the car back together as I didn't have a new hub/bearing assembly. The fault returned as i set off. I do now have the part ready to go on. Now having read through the abs control unit thread it's now making me think it could be a faulty unit. But that shows a G201 fault iirc. Just some advice or heads up before jumping up and down on breaker bar to crack the centre hub nut loose would be very much appreciated!!
