3DColorMFD ver. 7.8.1
You will need:
|Soldering iron 40 W|
|Nippers||Pliers||Knife||Thermocouples||And screwdriver Torx T10|
ATTENTION!!! When installing a color MFD, there are 3 most important points.
Bend all the latches and neatly remove the front of the case (with glass).
View from above
Then remove the substrate.
1.3 Cut the jumpers, we work carefully, so as not to damage the board.
It should look like this:
1.5 With the help of pliers, we bend the metal clamps restraining fullFIS display.
It is necessary to remove the display by gently heating the loop
with which it is soldered to the board, do not tear off the display as you can damage the dashboard board.
1.8. Then you need to remove all the LEDs that are were under the standard display
We make sure that there are no jumpers made of tin.
After removing the LEDs, clean the board from tin residues and rinse with alcohol.
For instruments with a halfFIS or fullFIS installed, it is necessary to find and cut
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
2.2 Remove LCD board from motherboard and Stretch the wires from MFD motherboard
to the blue and green connectors (grey — for Audi) 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.
2.5 Lay the wires in such a way that they do not interfere with the installation of white Light diffuser.
In clusters for the American market, there are no open hood and
oil level control resistors, and there are no oil level and temperature sensors in the engine sump.
2.7 The wires should be pulled from the back or as shown above.
Wires should not interfere with the assembly of the cluster.
So it’s not right!
2.8 Power connection
There are two types of power supplies
Before installing the power supply, you need to solder the wires to its contacts IN+, IN- and OUT+, OUT- ,
then apply a current of 12V to IN+, IN- , and connect the OUT+, OUT- wires to the multimeter.
Now we need to tune the output current. Using a small flat screwdriver, you should rotate tuning resistor
clockwise, until you have 5.5V output voltage on the multimeter.
Next, we place the power supply on the cluster`s back board and bring wires from the blue connector to its contacts.
How to do this, look at the connection diagram specifically for your car model.
Choose the place of installation of the power supply so that during assembly it does not interfere.
Choose the installation location of the power supply so that it does not interfere later in the assembly. For example:
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.
2.9 Before assembly, check the functionality of the module in your car.
After wiring, lay it so that they do not interfere with further assembly. Check wiring with multimeter, in Diode mode.
On the display, at the back, there is a piece of double-sided tape (if yours doesn`t have it, attach one). Don`t remove the protective film from it! We use it only as a support for the display!
|Do not solder these wires! Pins 6 and 7 are spare.|
|3.1 Cut off Red USB wire, we don`t need it.||3.2 USB cable should be fixed with glue.|
3.3 We take double-sided adhesive tape on a foamy basis, cut the squares 1cm X 1cm.
3.4 Collect these squares in 3 floors.
3.5 Place them so that nothing prevents you from mounting the module on the board.
3.6 Place the module so that it fits in the cluster`s window.
3.7 Cut off the main beam guide part. On the red line. Leave the semicircle.
3.8 Cut off the protruding part!
3.9 Install a white diffuser and cut off the excess (as shown in the picture).
Then place the display and align it so that it clearly fits into the cluster window.
3.10 IMPORTANT! For greater stability, after you have tried and calibrated it, fix its position with hot-melt adhesive.
3.11 Next, you need to glue the matte protective film so that the display does not glare in the sun.
Be sure to stick the film!
Otherwise, the display may be damaged!
To connect the turbo boost pressure control.
You will need to add one PIN to the dashboard 32 pin grey connector.
The other end of the wire must be connected to the engine ECU.
According to the table below, you should find the signal wire of the boost sensor.
When the engine is idling, the voltage on the wire should be between 1.6 and 1.9 volts.
With an increase in RPM (engine speed), the voltage on this wire should increase.
On diesel engines (AVB and others):
— 71st pint of ECU, green — red Wire (green with a red stripe);
On petrol (AWM and others):
— 101 pin of ECU, gray — blue wire (gray with a blue stripe).
In general, as I know, in all diesel 1.9Turbo, supercharging is connected to the 71st pin,
And the gasoline 1.8T is connected to the 101 pin. The color of the wire can vary depending on the year / engine.
Collect everything in the reverse order, without forgetting to calibrate the needles with the help of the VAG-com program.
6.1 To do this, connect cluster to the car (without cluster glass) and connect it with VAG-com.
6.2 Go to unit-17.
6.3 Select Test unit.
6.4 Make a needle test.
6.6. Tachometer — 3, 000 RPM.
6.8. Speedometer — at 100 km / h
6.9. Coolant temp. — middle
6.7. Fuel level — middle
Then check everything again
You can not turn the needles too quickly correcting the position, you can damage the motors of the needles
You can not turn the needles, when there is power on the device.
6.6 Put back the cluster glass and put the cluster back into the car.
7. Take a photo and post it on all social networks.
Go to auto club meeting and brag to your friends.
8. Show it to your girlfriend/wife with words: «Look what a cool thing I bought for just 20 b
