knock sensor replacement diagram needed

Unfortunately the Sprinter was not offered in the USA by Mercedes in 2007 as it was produced by Dodge as they were owned by MB back then.

So we don't have a manual on this specific engine but from what I remember they are in the same location as the 3.5L which means they are under the intake.

Here is the process for the 3.5L. Let us know if you have other questions but unfortunately we are limited to what was offered in the USA in the material that we have so hopefully this helped. Thanks

Good morning,

The sensors are under the intake manifold.

I attached 2 pictures for you of the location of the sensors.

Do you have codes for these? If you do, can you post the codes?
