Hi wondering if anyone can help me with a problem with my A5, a week ago I'm getting abs esp and parking brake malfunction lights on dash, I've done a scan and getting multiple faults, I have replaced the front left abs sensor but problem is still there, I get a feed from the aforementioned sensor wires via multimeter, could this possibly be a problem with the abs pick up ring which is part of the wheel bearing? I'm thinking if it were the abs module I would get no readings off any of the wheels, no reading via live vcds from front left wheel but other 3 are fine when car in motion, many thanks in advance
