Could anyone please point me in the right direction regarding changing the air filters on my car which has the 350 bluetec engine. Does anyone have a pdf with the change instructions and could you please let me know if so

Also in terms of resetting the system after changing the air filters do you need star for this or can you reset using something like an icarsoft portable scanner tool that I have?

Many thanks

They are plug and play so no resetting needed, you access them under the engine cover which lifts off, massive filters, the passenger side has the flow meter in it IIRC

I’ve had a look and can see where the two filters are located just not sure how to remove them and what needs to be disconnected/loosened first.

Having done a search there just seems so many variations not sure what is the ‘proper’ way of doing them
