AUDI Q3 TDI NON START NO ENGINE ECU COMUNICATION DIAGNOSTC AND REPAIR

Hi and welcome to the channel and here we have a Audi q3 witch was recovered in with a report of cut out and wouldn't restart so we inspected the vehicle and confirmed she would start intermittently and then cut out straight away we found no communications with all the important modules these modern vehicles require in order to work so lets see what we find although we have the fabulous autel maxys 919 elite the diagnostic machine can only tell so much so lets see what we find and if you like the video please subscribe for free and have a great day
