Characteristics of Air Intake Unit Versions 1 and 2

Characteristics of Air Intake Unit Versions 1 and 2

• There are different versions of the air intake unit and corresponding upper cover ( up to 05.04 Version"1" and after 05.04 Version "2" as a running change). If the Version "1" upper cover or housing produced up to 05.04 has to be replaced, replace the cover or upper housing of the air intake unit as well (you will only receive Version "2" components as the spare part).

• In the following figure, details marked with - A - indicate the status of Version "1", details marked with - B - indicate the status of Version "2".

• The changeover to version "2" will prevent water from penetrating the air intake housing through the various connection points.

• To prevent water from penetrating the air intake housing through the connection points of Version "1" components, at the factory a caulking strip is placed in the groove of the tongue and groove joint between the upper cover and the housing. In addition, the connection point between the inner cover and housing is sealed with a piece of butyl sealant.
