closed. The intake air must flow through the whole intake pipe. Its length is selected in such a way that the
pressure waves, produced by the inducting pistons, arrive at the right moment at the open intake valves for the
next induction stroke. The result is improved cylinder charge and thus an increase in torque.
At higher engine speeds (e.g. from 3900 rpm) the actuation to the variable intake manifold switchover valve is
interrupted - the variable flaps open as a result of the spring force. Through the shortened route the pressure
waves arrive in time even at higher rotational speeds before the closing of the intake valves to the combustion
chamber.

The intake manifold is assembled out of several magnesium pressure castings. When fitted together, they
produce the individual intake manifolds and the air collecting volume. The parts are sealed off to each other by
plastic. The intake manifold cannot be disassembled.
The individual intake manifolds each approx. 800 mm long, are arranged in a spiral shape around the air
collecting volume. A single intake manifold is assigned to each cylinder.
Each single intake manifold has a further opening to the air collecting volume in the middle. These can be
opened or closed by means of variable flaps which pivot through approx. 60°.
The variable flaps are attached to steel shafts. One shaft is installed for each bank of c
ylinders. The

interconnected flap shafts are closed by means of vacuum by the intake manifold switchover diaphragm unit.
When the variable intake manifold switchover valve is open, the vacuum is supplied from a vacuum reservoir
with check valve in the intake manifold. The reservoir volume is designed for about 5 operations without
renewed evacuation.
The variable flaps open by means of spring force.

System Control Unit
Position of the identification
For vehicle models 170, 202, 203, 208, 210, 215, 220, 230, 463 an identification plate is located on the fiber
optic cable wiring harness behind the radio on which the fiber optic cable modules (1, 2, 3, 4) specially fitted to
these vehicles are specified together with their exact length.
With models 129, 414 the identification plate is in the trunk next to the CD changer.
With model 168, the identification plate is in the passenger footwell in the area of the control unit box. If there
is no length specification on the identification plate, the respective fiber optic cable module must be removed
and the necessary length measured.
Vehicle model 163 does not have any identification plate.
With repairs, the individual fiber optic cable modules with corresponding length specification can be ordered
(see spare-parts documentation Group 82).

Fig. 6: Identifying Fiber Optic Cable Components Location
FIBER OPTIC CABLE, FUNCTION - GF82.00-P-4000-04A
The fiber optical cable consists of plastic with a fiber diameter of 1 mm. Each fiber optical cable is protected
against mechanical damage and against admission of outside light with the help of an orange-colored insulation.
The light for the data transfer in the digital data bus (D2B) has a wavelength of 650 nm; by comparison, visible
light lies in the range of blue with 400 nm to red with 800 nm. Optical attenuation of the light signal can occur
in the fiber optic cable. Attenuation of the optical signal in the fiber optical cable is dependent on:
the length of the line between the individual components
the bending radii when routing the fiber optical cable, which must have min. bending radius = 25 mm
the condition of the insulation of the fiber optical cable
A passive connector; this is used when a component is removed from the digital data bus (D2B) due to a
fault.
To ensure the functional availability of the remaining components, the digital data bus (D2B) is closed again
using a passive connector. The fiber optical cable has two different connection ends:
The fiber optical cable input, which is the output to each control unit. This is marked in "white".
The fiber optical cable output, which is the input to each control unit. This is marked in "red".

After calculation of the route, the navigation processor makes up a list of the streets along the route. This route
list is used for navigation. It can be displayed during navigation by pressing the "I" (INFO) and "RTE" (Route)
buttons.
Route updating
If the driver deviates from the calculated route, a new route list is automatically calculated by the navigation
processor. The current position and the direction of travel are taken into consideration, and the new route is
optimized accordingly. This is accomplished without any message on the display.
Circumventing traffic jams with "Traffic jam" menu key function
After a traffic jam is reported on traffic radio and before reaching the affected section, a route can be calculated
for driving around the traffic jam. For this purpose, activate the "Traffic jam" menu and enter the length of the
traffic jam including the distance to the start of the traffic jam.
The "Traffic jam" function is also available for Federal and State highways as well as for inner city areas.
Trips outside the digitized map area
If the vehicle leaves the digitized DVD map area (e.g. driving into a multi-level car park), then no route can be
calculated or updated. "OFF ROAD" appears on the display. Upon leaving the map boundary, the display "OFF
MAP" appears.
Destinations which lie outside of the digitalized map area cannot be taken into consideration on calculation of
the route.

When traveling within the digitized map area, the following information calculated by the navigation processor
is available to the user (partially to be called with "I" (INFO) button):
Route list indicating the distance to be driven on the affected streets or roads
Distance to destination and estimated time of arrival (the time must be set correctly for this purpose).
Driving recommendations
Arrow indicating the driving direction
Current location, in other words name of city and street, latitude and longitude
Name of the next road into which the vehicle should turn
Distance to next turning point specified in units of length or as bar graph (3)
The navigation processor generates graphic signals for the navigation system symbols.
Actual route guidance is supported by voice output via the vehicle loudspeakers.

Driving direction recommendation

The data is determined by the navigation processor and transmitted to the radio and navigation module
(A2/56) The current route guidance is primarily supported by the voice output (English).
The scale of the displayed map can be changed in increments. In addition it is possible to select whether the
map is aligned in the direction of motion Head-Up ) or toward the north North-Up ). The graphical signals for
map illustration is generated by the navigation processor.

When traveling outside of the digitized map area (e.g. company grounds, parking buildings, dirt roads,...),
however still within the DVD map boundaries, the navigation processor switches over to "navigation system in
non-digitized map area".
On the radio (A2) display the following message appears:
"OFF ROAD"
If the vehicle is also outside the DVD map limit, the following message appears:
"OFF MAP"
In both cases, only basic location finding is accomplished with correction using the GPS data.
A (limited) route guidance can be conducted only with specification of the:
Distance from the destination as the crow flies
Direction to the destination (as an arrow)
After reentering the digitized map area, the system automatically continues with "navigation system in digitized
map area". The possible streets/roads on which the vehicle may be located are determined with the aid of GPS
location finding. During this process a slight delay in the route guidance may result.
The road data of several Central European countries are stored on the navigation DVD, so that the "OFF
MAP" message will not appear, if borders between the stored countries are crossed. No special foreign country
DVD has to be inserted.
