Engine management light came on when put on the Vadcom Code P0036 Heated Oxy Sensor (heater control circuit bank 1 - sensor 2) AA came out and confirmed it, needed to call the AA because i have breakdown repair cover and they have to come out and check it as a fault in order to pay out. Anyways took it to Russell Audi specialist in Wemberly, they also confirmed the it to be the señor 2 and change it and cleared the fault.
Two days later the code is back has anyone got an idea if it may be something else...could it be the wire that runs to the ECU that has a break in it????
Your thoughts please.
