The pressure switch is also part of your VWs idle stabilization system and will raise your engines idle speed to compensate for low pressure. If you have replaced all the other switches trying to sort out your high idle issue, this may be your last option.
The VW power steering pressure switch is bolted through the pressure line to the power steering pump. When it’s time to replace your switch you will need to have some new power steering fluid to top off your system.
