Description

This kit is intended for customers with tuned 2.0L TDI / BMW N47 cars who experience low rail pressure faults ONLY.

A slight percentage of tuned cars will throw low rail pressure faults at WOT in higher gears after installing the metering bypass kit. This custom socket and depth-setting punch are a quick, easy, and accurate way to adjust your car’s cascade valve and fix the low rail pressure issue. Please see the product instruction document linked below for a more in-depth description of what this adjustment does.
