VW Jetta, Golf, New Beetle 1.9L TDi Unichip PnP Installation Instructions

Although the PnP kits and ECU’s are identical, the New Beetle’s EC’s location is different than the Jetta/Golf; therefore these instructions are split – the first section describes Golf/Jetta installation and the second section describes Beetle installation.
(2) The ECU connectors lock and unlock by pulling the “T-handle” located at the connector’s edge. Look at the locking handles on the PnP harness and familiarize yourself with the mechanism before trying to remove the OEM plugs.
(3) When trying to remove the OEM Plugs from the ECU, getting your fingers into the T-handles can be difficult. You can gently pry the T-handles back using a screw driver.
