2014 B3 Biturbo Oxygen Sensor

Post by dougiewoop » Mon Sep 18, 2023 2:54 pm

Hi all,

My new to me B3 Biturbo is showing fault code 12A801 'Oxygen Sensor after catalytic converter 2, electrical: short circuit to B+'. Does this mean I need a replacement sensor please and if so could anyone please share the correct part number and where to get hold of one?

Many thanks!!
