Hello Chris,

What engine, and what codes are set please?

Has the valve been checked?

Ive never replaced a knock sensor in a Vectra.

have replaced knock sensor and it's a v6 .

Hello again Chris,

I meant to say above, has the valve timing been checked?

The V6 engine is a very fussy engine, and special tools are needed to do a timing belt.

The engine is prone to engine noise which might log codes for the knock sensor.

Can you tell me the code you get now?
