Hi. brand new member here. Can anyone tell me where the bank 1 oxygen sensor is on my 2007 V50 2.od, I think it's just beyond the manifold. Can you replace it from above? Thanks for any help.

 

Not many diesel experts here (wasn't available in the US), but there are (I presume) two sensors - one pre-catalytic converter, and one post-cat. On my petrol 2.4i variant, I seem to remember both sensors being relatively easy to get to. If you can see 'em, you can swap 'em easily! ;-)

 

Thanks habbyguy, could be different with a 4 cylinder but I'll have another look.
