Second Generation Faults & Fixes
Hi,
I own a 2008 R56 Cooper S which recently threw an engine light.
I recently completed a 100k service so was a bit surprised but nevertheless run my OBD scanner and it came up with code P0131.
(P0131: Heated oxygen sensor (HO2S) 1, bank 1 - low voltage)
I did some research around the place...
