Hi everyone,

my 156 2.0 JTS keeps have the good old MCSF message, which my diagnostic gizmo tells me is "No signal from oxgen sensor Bank A sensor 1" so ok I have a bust sensor. I can change this myself no problem, but which is it?

Looking from the front of the car I have 2 sensors pre-cat and 2 post-cat, so which is which?

Thanks!

Sam.
