Is the idle in your MKIV VW erratic or high? Have you replaced all other components but are still stumped? This power steering pressure switch from Euromotiv might be your solution.

When this sensor notices that power steering pressure is lower than it should be, your engine compensates. Your motor increases RPM to get more fluid moving through the system and make it effective again. So if you are still looking for your high idle problem, check this unit out from Genuine VW/Audi.

When doing service to the power steering system, you will most likely loose some fluid. Browse our website to choose the best fluid for your application. OEM and high performance, replace it now to extend component life and get stock performance.

This sensor is made for the 28-40 bar range.
