1.6 A/C Air Distribution Housing Defroster
Outlet Door
♦ Beginning May 2007, a heater air distribution housing with a
door -A- (in the air outlet to the defroster vents in the instrument
panel) without a side cut-out -C- is gradually being installed.
On vehicles without A/C, the change to the door has no influ‐
ence on the heater control (the door is controlled only by
adjusting the Climatronic control module -J255- ).
♦ Beginning May 2007, a A/C distribution housing with a door
-A- (in the air outlet to the defroster vents in the instrument
panel) without a side cut-out -C- is gradually being installed.
With the introduction of the door with the side cut-out -C- the
Climatronic control module -J255- is changed (the door must
be opened further by the heater control due to the missing cut-
out -B-, in order to direct the same amount of air to the
windshield). Refer to the Electronic Parts Catalog (ETKA).
♦ The Climatronic control module, part number "8J0 820 043"
through index "AA" may be installed only in vehicles which
have an A/C air distribution housing with a door in the air outlet
to the defroster vents in the instrument panel with a side cut-
out -B- that has been or will be installed (exception: vehicles
that will only be driven in tropical regions).
♦ On vehicles, which will be driven in tropical areas only, to pre‐
vent the windshield from fogging up on the outside in the area
of the "Defrost" outlet, a door in the air outlet to the defroster
vent in the instrument panel without a side cut-out -C- has al‐
ready been installed since March 2007. Since, under these
conditions (no winter operation) the windshield does not fog
up from the inside, a Climatronic control module part number
"8J0 820 043" through index "AA" can be installed in these
vehicles.
♦ With the Climatronic control module part number "8J0 820
043" from index "AB" the "adaptation " function (in adaptation
channel "30") the door -A- (in the air outlet for the defroster in
the instrument panel) can be entered (Climatronic control
module adapting) using Vehicle diagnosis, testing and infor‐
mation system -VAS5051B- in the "Guided Fault Finding"
function.
