Safety precautions

DO NOT!

ATTENTION!!! When installing a color MFD, there are 3 most important points.


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. It is necessary to cut the power paths going to the pins 
17,18,19,

then check that they are not voltage-free, you need to supply power to the cluster 

and check with a tester, one probe into the ground of the second to each pin 17,18,19. Should be 0v . Paragraph 10


3. 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. 

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

1.   Remove the arrows (scroll counter-clockwise and simultaneously pull ourselves).

Either Using knives for oil or spatula, shoot the arrows from their shafts. It is necessary to put

A cardboard or napkins between the nomes and the base of the device to avoid damaging it. Necessary

Pull the arrows up to yourself.

2.                 Then remove the substrate.

3. Remove the speedometer and tachometer motors.

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

5. Remove the display

6Remove temperature sensor

It should look like this:

We make sure that there are no jumpers made of tin. 

After removing the LEDs, clean the board of the residues of tin and rinse with alcohol

7VERY IMPORTANT:

For instruments with a BC installed, it is necessary to find and trim
tracks from
 the pins of the control of the standard BC on the board 

of the instrument panel (from the pins 17, 18, 19  of the grey connector)
Below are photos from some instruments.
On your device, the tracks may be located elsewhere

10.             We start to build wires according to the table. Wires are cleaned of

Isolation and twisting, ludim and cut off excess.

12. Through the holes in the board of the device, we extend the wires to the blue

And green connectors.

13. Using the tester, we find the wires we need and solder them to the feet

Connector according to the table.

Full size image

It is necessary to twist the wires of the connection to the CAN-bus into a spiral.

 

Lay 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.

9-pin of the blue connector is connected to the e — IN on the power supply board.

23 the leg of the blue connector is connected to + IN On the power supply board,

Contact to

 OUT
 Connects to 42 pin MFD

+ OUT Connects to the 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.

  

20. Cut off the main beam guide part.

On the red line.

Leave the semicircle.

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.

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!

 

 

28. In order to save the driving light indicator, we cut a slot in the light guide for the screen.

To connect the boost pressure control.

You will need to add one PIN to the dashboard 32 pin grey 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 ECconnector

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
