VW Polo EPC error and how to replace a faulty brake switch

My EPC warning light on the dashboard stand on indicating an error. Using an OBDII scanner it reported the brake switch as the issue for my car. The EPC switch covers a multitude of function so good luck with that. 

If you are buying a brake switch make sure you buy the correct part. Some have 4 pin connectors and some have 2 pin connectors.
