Hi all,today I replaced the nsf wheel bearing on my mates A4,(was the full hub type one with 4 bolts in the back) and upon starting the ABS,T/C and brake pad lights came on,also the speedo no longer works.Code read the vehicle with a launch computer and came up with fault code 00283(front left speed sensor) and something about short circuit to positive,unplugged the sensor and re read for faults and got the same code,so assumed I'd damaged the sensor,fitted a new sensor and the problems still there.All the wires look ok and the sensor looks to be lined up with the gear on the driveshaft,reading through another thread on here looks like someone else had the same problem however there was no explanation to why,anyone here know what this could be or had the same problem?It's a 52 plate 1.9tdi fwd
