UK-POLOS.NET - THE VW Polo Forum

Hi all, new to the forum
My daughters polo keeps throwing this fault, which from the looks is 02 sensor circuit Bank 1 sensor 1, I have replaced the sensor with a Bosch one but now after around 8 miles puts engine warning light on a says its the same fault?
has anyone got any suggestions on why it would do this and tips on trying to resolve, its driving me crazy.
many thanks Nick

Follow the wiring loom back from the sensor. Its not uncommon that the wiring breaks up on these and then causes a fault
