Hi everyone am new to this site so please excuse me if in wrong area. So I have A7 3.0 tdi which had engine warning light pop up. So my son put the carista obd analyser on and it came up with code for egt sensor, Bank 1 sensor 1. So rang audi and they give me part numbers for 2 sensors. Just over £300 for both sensors. So fitted both new sensors today.fitted one at a time and then both new ones. Reset fault light but only stays off for 2 starts of the engine and then fault comes back as bank 1 sensor 1. So my question is should the Carista reset the code or does the car need to go to Audi. Any help would be appreciated. Gray
