PD170 (BMN) G28 crankshaft sensor

[syko]

Hi

I have a Golf gt tgi pd170 (BMN engine code)

It didnt start yesterday and gave me fault code P0321 - engine speed sensor

I have purchased a new sensor but cant find 100% its location , some people saying to remove the oil filter and housing and others saying its in the gearbox

Could anyone confirm 100% were it is located

Thanks for reading
