MN3001 Metalnerd Socket for Bosch Triangular Bolt
Replace your New Beetle's injection pump seals or adjust your TDI injection pump timing with this special socket for the anti-tamper screw on all 1998-2003 New Beetle TDI VW injection pumps. This socket is required to loosen and tighten the triangular headed anti-tamper screw on the quantity adjuster's top cover as shown in the picture. Use your 1/2" socket or wrench to drive this socket. A 13mm will work in a pinch.
