In addition to the functions described on the penultimate page for the vehicles marked with an asterisk available from software “SB” in the upper right corner of the control unit sticker: If button A, B or C was previously pressed, the flaps always open to ½ first when button D is pressed. Pressing button D again opens the flaps ¾ and pressing the button a third time opens the flaps ¼. Repeated presses will take you back to positions ½ -> ¾ -> ¼ etc.
As a special feature, we also offer a teach-in function for the flaps if, for example, a servomotor is replaced or newly installed. To do this, press and hold the C and D buttons simultaneously for 8-9 seconds. The servomotors then (re)learn the mechanical stops of their exhaust flaps.
Installation has to be carried out expertly by a qualified person:
-
Switch off the ignition.
-
Identify the exhaust flap electric actuator on the left-hand side. It is located on the left above the rear silencer (green circle). On some models, the servomotor can also be located behind the rear silencer.
The electrical plug must be unplugged. If it is dirty, please clean it without water or dry the environment as the plug and environment should be dry.
-
Depending on the vehicle model, loosen any screws and fasteners on the rear bumper to get better access and a look behind the bumper.
-
The control unit is basically waterproof and can be installed outside the vehicle in the underbody. However, before starting the assembly, check whether the control unit can also be installed inside the trunk. For example, under the trunk floor mat, there is space to the left next to the 12 volt battery. Then the large rubber stopper in the floor pan must be removed and the two electrical cables routed to the outside and the hole then sealed again with the cut rubber stopper. Alternatively, the rear left or right side panel could be considered.
-
Pull the release of the plug (if available) backwards a little (1). Then press the release (2) and at the same time pull the plug out of the electric servomotor of the exhaust flap (3). You can also practice this well in advance on the identical plugs/sockets of the exhaust flap control unit.
-
The removed plug must now be connected to the matching counterpart of the exhaust flap control unit.
-
Pull the electric cable of the exhaust flap control unit up to the exhaust flap. If necessary, you can also hide the electrical cable under the heat shield. Usually a few small screws have to be removed and reattached later.
-
Now connect the plug that was separated from the exhaust flap to the matching socket of the exhaust flap control unit until it snaps into place (1). Then slide the gray lock of the plug towards the socket so that the plug can no longer be detached (2).
-
Then connect the plug of the control unit to the servomotor of the exhaust flap until it snaps into place. Push the gray lock in the direction of the servomotor so that the plug can no longer come loose.
-
Fasten the cable to the electrical wiring harness in the bumper, e.g. with cable ties. Make sure that the connection line on the servomotor of the exhaust flap has enough room to move and is not under tension.
-
Identify the exhaust flap electric actuator on the right side. It is located on the right side above the rear silencer (green circle). On some models, the servomotor can also be located behind the rear silencer.
The electrical plug must be unplugged. If it is dirty, please clean it without water or dry the environment as the plug and environment should be dry.
-
Repeat steps 5 to 9 on the right side.
-
Fasten the cable to the electrical wiring harness in the bumper, e.g. with cable ties. Make sure that the connection line on the servomotor of the exhaust flap has enough room to move and is not under tension.
-
Store the control unit in a suitable place where it is not unnecessarily exposed to excessive heat or constant water exposure. Secure the control unit firmly at suitable points on the vehicle, e.g. with cable ties. (See also point 4)
-
Switch on the ignition and carry out a functional test of the exhaust flap control. If this works as described, reassemble all parts of the bumper in reverse order.
Attention! Exhaust flaps can become stuck after a few weeks or months if left in a fixed position for too long. Therefore, ensure that the flaps move regularly.
Remote control
The following functions can be controlled by briefly pressing a button: (The engine must be running for this.)
- A: Exhaust flaps permanently OPEN
- B: Exhaust flaps permanently CLOSED (Attention! Avoid full load / very high engine speed!)
- C: Exhaust flaps opened and closed by the engine control unit (Serial)
- D: Exhaust flaps can be opened individually to a half open position (Freestyle)
In addition, you can reconfigure the exhaust flap control unit by yourself via
the remote control:
From the factory setting, the exhaust valve control unit remembers the last
selected operating mode that was active when the engine was switched off.
If you want the exhaust flap(s) to be always in A, B, C or D mode, independent of the last setting when starting the engine, you can set this. While the engine is running, press and hold A, B, C or D for 7-8 seconds for the desired mode. When the button is released, the exhaust flaps open and close again twice for audible acknowledgment.
If you want to return to the mode where the exhaust valve control remembers the last flap position when the engine shuts off, press and hold one of the A, B, C or D buttons for 4-5 seconds. When you release the button, the exhaust flaps open and close again. (memory mode)
The exhaust flap control is equipped with an information channel via which the exhaust flaps can communicate with the engine control unit in order to notify it of a malfunction in one of the exhaust flaps, for example. The information channel is activated at the factory. If the information channel is to be deactivated, hold down the C and D buttons simultaneously for 5-6 seconds. When the buttons are released, the exhaust flaps open and close twice.
To reactivate the information channel, hold down the C and D buttons simultaneously for 2-3 seconds. When the buttons are released, the exhaust flaps open and close once.
With a sliding flap from the remote control, two or all four buttons can be hidden.
General information: no approval in the traffic law, installation and operation of the device at your own risk, no liability for damage.
Changing the battery for the remote control
Loosen the 3 screws on the back of the remote control with a small Phillips
screwdriver (PH0) and put the screws aside. Place the remote control with the
button side down and remove the back of the case. Remove the used battery from
its holder and replace it with a new one of the same type (12V battery type
A27 or 27A). Pay attention to the correct polarity (+/-). Reassemble the
housing parts and screw them together.
Notes on battery disposal
The remote control includes a 12V type A27 or 27A battery. Therefore, we are
under the Battery Act (BattG) obliged to point out the following:
You as the end user are legally obliged to return used batteries and
rechargeable batteries. Used batteries may contain harmful substances which,
if not properly stored or disposed of, could damage the environment or your
health. In addition, batteries contain important raw materials (such as iron,
zinc, manganese, nickel) that can be recovered if properly disposed of.
We work together to collect the batteries with the Stiftung Gemeinsames
After use, you can either return the batteries to us, send them to us or
return them free of charge in the immediate vicinity (for example, in stores
or in the municipal collection points and the collection boxes described). If
possible, the batteries should only be handed over in discharged condition or
protected against short circuit by attaching an adhesive strip. The delivery
in sale points is limited to the usual amount for end users and to those waste
batteries that leads the distributor as new batteries in his assortment or
led.
The crossed-out wheeled bin sign means you must not dispose of batteries and
accumulators with your household waste. If under this sign in addition one or
more of the following symbols are printed, this means:
Pb: battery contains lead (> 0.004% by mass)
Cd: battery contains cadmium (> 0.002% by mass)
Hg: battery contains mercury (> 0.0005% by mass)
Notes on the disposal of WEEE
As an end consumer, you are obliged not to dispose of waste electrical and
electronic equipment via household waste, but rather via a municipal
collection point. The collection of these old devices and the correct
recycling of raw materials protects the environment and protects the natural
resources.
Instructions for the disposal of packaging
Please do not throw packaging waste into the household waste, but feed it to
the separate collection. For this purpose, there is usually a bin for
paper/cardboard as wellas a separate bin or the yellow bag for plastics.
Alternatively, these materials can also be sent to a municipal collection
point. Collecting these materials and recycling these raw materials properly
protects the environment and conserves natural resources.
