Safety precautions

DO NOT!

ATTENTION!!! When installing a color MFD, there are 2 most important points.

 

On some cars it is necessary to record the cluster to disable the factory FIS. On B6 this is not very important. On B7 this must be changed. Using VAG-Com ( VCDS) check/modify the following values.

 

17-Instrument 
10-Adapation 
Channel 19 
x? xxx: 
On-board computer 
0 - only level 2 (long-term memory) 
1 - levels 1 and 2

xx? xx: Driver information system (DIS) 
0 - DIS 1 
1 - Highline without DIS 
2 - DIS 2 

 

Change these values so the second digit is either 1 or 0 and their digit is O thus giving x10xxx or x00xx (x10xx works better). The x's will remain unchanged from

Using VAG-COM (VCDS) in 19th adaptation channel, switch the cluster to "trip 1 and trip 2" mode and
"Only DIS 1" (Second number = 1 and third numbers = 0)

 

(Following info from Remnevolt on Drive2.ru)

 

 
 

1. You need to configure the power supply to 5.5v.

The MFD operates at a voltage of 5.5v. When you connect the power supply to the MFD

you should make sure that the output of the contacts is 5.5v, otherwise it will damage the processor! Paragraph 18


2. You need to rinse all the soldering points. Install very carefully.

After soldering the wires, it is essential to rinse the soldering points with special flushing agents

or isopropyl alcohol. During washing, do not allow alcohol to enter the display or under the display and its board!

 

 

 

1. Disassemble the cluster.

1.1 With a screwdriver torx T10, unscrew the two screws edges on the rear of the instrument panel.

Bend all the latches neatly remove the front of the case with glass

View from above

1.2 Remove the needles.

There are 2 ways to do it:

  • scroll counter-clockwise and simultaneously pull it to yurself or

  • using using non sharp butter knives or spatula, shoot the arrows from their shafts.

Its better to put paper between the knives and the base of the device to avoid damaging it.

Pull the arrows up to yourself.

1.3.                 Then remove the substrate.

14. Remove the small displays under the speedometer and tachometer and white plastic.

1.5. Remove the display

It should look like this:

Remove LED

VERY IMPORTANT:
For instruments with a halfFIS or fullFIS installed, it is necessary to find and cut

tracks from
the pins of the control of the standard BC on the board of the instrument panel (from the pins 22,23 )
Below are photos from some instruments.
On your device, the tracks may be located elsewhere

2. Installation

2.1 Start to build wires according to the table. Wires should be cleaned from Isolation, twisted and tin plated.

2.2  Remove LCD board from motherboard and Stretch the wires from MFD motherboard

to the blue and green connectors through the holes in the cluster`s board.

 

  2.3  Take the multimeter, set it to Diode (Ring) mode.

Using multimeter and wiring diagram,  find the wires you need and solder them to the connector pins.

The 2nd way to install, is to solder to the points on the dash board.
 

Сhoose a way that will be more convenient for you.

 

ay the wires in such a way that they do not interfere with the installation of white

Light diffuser.  

17. Wires should be pulled from the back side Or as shown above,

So they do not interfere with the assembly of the device. So it's not right!

Attention!

18. Before installing the power supply, you need to solder the wires to it contacts + IN - IN and + OUT - OUT ,

then apply a current of 12V to + IN - IN , and connect the + OUT - OUT wires to the tester.

Now we need to adjust the output current. Using a small flat screwdriver slowly rotate

the special metal knob (figure 1 in the picture.) Clockwise

Arrow, until, at us on the tester will not appear 5,5v in an output voltage.

Next we place the power supply unit on the back side, we bring to its contacts the wires from the blue connector.

2 pin of the green connector is connected to the e - IN on the power supply board.

18 pin of the green connector is connected to + IN On the power supply board,

Contact 
+
 OUT
 Connects to the 38 pin MFD

- OUT Connects to 39 pin MFD

Choose the place of installation of the power supply so that

during assembly it does not interfere. Here are the possible

Options:

Attention!

After wiring, lay it so that they do not interfere with further assembly.

Need to  call all contacts and check on the table to avoid confusion anywhere.

  

22. Before installing the display, you need to glue two-way

cattle into three layers on the back of the display to lock the display.
Attention, you do not need to attach modules to the board!
It is enough simply to remove an additional support from a double-sided adhesive tape

without removing the protective layer from the side of the module board.

The USB cable should be fixed with glue.
Red USB wire do not use, cut it off.

 

After you solder the wires and set the display to its place,

you need to test the MFD performance in the car to make sure everything is properly installed and working well.

23. We take double-sided adhesive tape on a foamy basis, cut the squares 1cm X 1cm.

24. We collect these squares in 3 floors.

25. And we place them so that we do not have anything to do with mounting the module on the board

   

26. Place the module so that it is placed in the window of the device

27. For greater reliability, when the module is already installed on the board,

and you calibrated it in the window so that there were no distortions, it is better to fix it.

Its hot glue along the edges of the module.

Next, you need to glue the matte protective film so that the display does not glare in the sun.

Attention! Be sure to stick the film!
Otherwise, you may damage the display!

 

To connect the boost pressure control.

You will need to add one PIN to the dashboard 4 pin green connector.

And the second end of the wire needs to be connected
the signal wire of boost sensor, on this wire at idle should be 1.6v,
with increasing PRM the voltage should increase.
If your motor is not in the table, find the boost sensor under the hood, it has 4 wires,
Use a multimeter to determine the signal wire, remember its color and find this wire in the ECU connector

Usually it is blue - gray wire (blue with a gray bar) to the incoming

On the 101st contact of a smaller brain connector.

On diesel engines (AVB and others): 
- 71st contact of the motor brain, green - red Wire (green with a red stripe).

On petrol (AWM and others): 
- 101st contact of the motor brain, gray - blue wire (gray with a blue stripe).

In general, as far as I understand, at all B5-x diesel 1.9T supercharging is connected to the 71st

And the gasoline 1.8T is connected to the 101st contact. The color of the wire can vary depending on the year / engine.

And then we collect everything in the reverse order without forgetting to calibrate the needles with the help of the WAG-com.

I.       To do this, connect the device to the machine without installing the glass, connect the VAG-com,

 

Ii.       Go into the 17-unit dash panel

Iii.       Select test performers.

Iv.       Choosing in turn a tachometer, temperature and the rest, the arrows in turn will be

Do a turn on the whole scale, and then freeze on:

1.      Tachometer - 3 thousand revolutions

2.      Pace. Coolant - middle

3.      Fuel level - middle

4.      Speedometer - at 100 km / h

V.       Then turn off the power from the device!

Vi.       And set the arrows correctly rotating them in the desired direction.

Vii.       Then check everything again

Viii.       You can not turn the needles too quickly correcting the position, you can to damage the motors of the needles

Ix.       You can not turn the arrows when there is power on the device.
