Had the ecu light come on in my missus's Audi A1 1.6tdi which brought up P242B code bank 1 sensor 3 which I replaced, cleared fault and everything was fine for a week till it came back on with the same code.
Could it be a bad sensor or is there something else causing this sensor to bring the light on like the cat ?
