Wastegate Calibration Harness

The CTS Turbo Electronic Wastegate Actuator Extension Harness (Part # CTS-WH-003) is an essential tool for simplifying the calibration and troubleshooting process for Gen3 TSI engines. This harness enables you to connect and set the wastegate voltage on a new turbo or actuator while it's off the vehicle, on your workbench. This eliminates the need to access the tight engine bay for adjustments. Utilizing this extension harness streamlines the process. Simply connect one end to the vehicle's electrical connector and the other to the turbo. With the ignition on (engine not running), you can then use diagnostic tools like VCDS or OBD11 on your computer to calibrate or troubleshoot the wastegate voltage at your convenience. This can help resolve common diagnostic trouble codes such as P2563, P00AF, and P0045. Key features include easier wastegate voltage calibration without the turbo installed, troubleshooting wastegate operation, and saving time and money by simplifying adjustments. The harness offers convenience and an ease of adjustment, removing the need to work under the car. This extension harness is designed for all Gen3 TSI engines. Specific fitments include various models of the Volkswagen Jetta (2014.5-2019, 1.8T & 2.0T Gen3), Volkswagen Golf, Sportwagen, Alltrack, GTI, Golf R (2015-2019, 1.8T & 2.0T Gen3), and Audi AllRoad, A4, A5 (2017-2019). The detailed fitment table further specifies compatibility across numerous Audi and Volkswagen models, engines (including 1.8T, 2.0T, 3.2L V6, and TDi), and drive types (FWD, Quattro) across various model years, from the Audi A3 8V (2014-2020) through the VW Mk7.5 Golf R (2018-2021).
