Accessing valley hose & sensors on X350


(Brian Ternamian) #1

I am currently having a code for a knock sensor causing restricted performance. From what I can glean from extensive searches you have to remove the intake Manifold to access the sensors and hose.

Do you (or anyone) think the knock sensors can be accessed through the front of the intake manifold by removing the throttle body and the unnamed part in the illustration below?

It might (should) be easier then removing the entire intake manifold which I have done on a 2003 X308 and was bear of a job.

I posted this in the EGR valley hose thread, but haven’t received any feedback yet. I thought I’d cover my bases.

Best regards, Brian
