Original BMW Media Blasting Wand for Tangential Port, BMW 335d and X5 xDrive35d (2009–2013)

The Original BMW media blasting wand for the tangential port, part number 81-29-2-356-969, is a service tool head that works with a walnut shell blaster to clean carbon deposits from the intake valves of the M57N2 diesel in the 2009–2011 BMW 335d and 2009–2013 X5 xDrive35d. It connects to the walnut shell adapter and directs blasting media into the tangential intake port. The wand is made in Germany. Over time, carbon builds up on the intake valves of these diesels, and BMW's M57N2 is especially prone to it. Heavy deposits can lead to poor performance and check engine lights.

A 24-month parts warranty covers Original BMW Parts bought from PMB.

Walnut shell blasting is used to clean carbon deposits from the intake valves. This wand is specific to the tangential port, and it is also referred to as a media blasting head. The blaster unit and walnut shell adapter it attaches to are separate items.
