2005 VW Passat 1.8T Tiptronic Transmission Fault Codes P0798 and P2716 - Unable to Shift into High Gear and Limp Mode

Model: 2005 VW Passat Fault Code: P0798 Posted: 2021-04-20 10:17

I own a 2005 Volkswagen Passat equipped with a 1.8L turbo engine and Tiptronic transmission. The vehicle is currently displaying fault codes P0798 and P2716, both related to the transmission system. The car fails to shift into high gear and is stuck in limp mode. I'm seeking advice on the most effective troubleshooting steps and potential repair solutions for this issue. Any insights into whether these codes point to a sensor failure, hydraulic problem, or electronic control module malfunction would be greatly appreciated.
