We are in Sunny St Austell today investigating a "knocking" noise and ABS light on a Peugeot 206.
The ABS issue was easily diagnosed as corroded connectors under the passenger seat. These were quickly rectified with a bit of cleaning and clearing the stored trouble codes.
The culprit of the "knocking" noise was a faulty top strut mount on the near side of the vehicle. A quick phone 'round our suppliers came up with the faulty part at a very reasonable price. We are currently fitting it for the Gentleman now.
