2013 VW Jetta - Stalls/No Comms when hot

Mario Rojas (aka Super Mario Diagnostics) has been repairing cars since 2013 and sharing his repairs on YouTube for the last five years. Fitting to his username, he primarily focuses on diagnostics and troubleshooting – and he’s garnered quite a following doing so. He currently has over 52 thousand subscribers on YouTube and over five million total video views.

In this post, Mario relies on ALLDATA information and its interactive color wiring diagrams to diagnose a strange stalling problem from the 2013 Volkswagen Jetta. After some solid analysis inside ALLDATA and some targeted testing under the hood, he was able to zero in on the problem and repair the vehicle. See the whole video for all the details.
