Hi Chaps,
Has anyone seen this code before on a tdci ?
P0325 Knock sensor 1 circuit bank 1.
code will erase but soon returns.
have checked knock sensor and replaced.
have pinned wiring out all ok.
i am suspecting an injector problem
car starts ok but has slight diesel knock especially from cold, also smokes slightly from cold, idle is uneven as though partially on three cylinders.
when warm after about half hour car is much much better.

does the description bank 1 refer to cyl 1 ?

Cheers
dave
