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 and neatly remove the front of the case (with glass).

Bottom view

1.2 Remove the arrows.

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.

 Then remove the substrate.

1.3 Cut the jumpers, we work carefully, so as not to damage the board.

It should look like this:

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.

1.5 With the help of pliers, we bend the metal clamps restraining fullFIS display.

1.7  Solder the plume of the standard display and remove it.

On some instrument panels, the plastic base of the OEM FIS is soldered to the board pretty hard,

to dismantle it — remove the tin, using a soldering iron and a special vacuum.

9. Then you need to remove all the LEDs that are were under the standard display

An example of Skoda Octavia`s cluster with MFA in a small screen above the tachometer..

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 (grey — for Audi)  through the holes in the cluster`s board.

	2.3. IMMO 2 If you have a 1J0 comfort unit installed.  To display open doors and a range of data, you need to determine the type of comfort unit.   Or your car is Seat Leon 1M. Be sure to stretch the wires from the comfort unit to the cluster. The comfort block 9 -> 8 pin of cluster`s outputs (CAN-H Comfort) of the green connector. The comfort block 6 -> 9 pin of cluster`s outputs  (CAN-L Comfort) of the green connector.

Be sure to twist in a spiral the wires, which you will be connecting to CAN bus. Comfort CAN bus — 8 and 9 pins of Green connector; CAN-bus motor — 19, 20 pins of Green connector.

C.2.4. If these wires are NOT connected to the comfort unit
you need to disassemble the comfort block and make sure that there is a CAN-bus chip

2.5. IMMO3 Cluster Installation in a vehicle with IMMO2
If you are installing IMMO 3 cluster in a car with 1J0 CCMS (comfort unit) — you shoul remove 2 resistors from the cluster board.
These resistors are coming from 8 and 9 pins of the green connector.

 

2.6. If you are Installating IMMO3 cluster in a vehicle with IMMO2,

you should activate the ambient temperature sensor in the cluster`s EEprom.

Passat B5 You need to change 1ef from 08 to 01 line 0001E0 column F

Golf 4 Cluster 1J0920806G no fis no show temp in dispay You need to change 1e5 from 2B to 2F line 0001E0 column 5

 

Change 2B in 2F and work

I changed that one 1E0 column 6 from 2B to 2F and it works

 

2.7.  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.

2.4 Be sure to twist in a spiral the wires, which you will be connecting to CAN bus. Comfort CAN bus — 8 and 9 pins of Green connector; CAN-bus motor — 19, 20 pins of Green connector.

There are 2 ways to connect CAN bus wires. Choose what is convenient for you.

	1-st way: solder the wires to to the pins of the green connector	2-nd way:  solder the wires to the points, indicated in the photo

2.5 Lay the wires in such a way that they do not interfere with the installation of white Light diffuser. 

     

2.6 If you have  noFIS or halfFIS dashboard, you need to solder the wire

from  36 pin of MFD board to the LED`s cathod, on the dashboard.
If you have FullFIS, this wire does not need to be soldered!

Important!
If you have NoFis or Half FIS,
you need to remove 3kOhm (302 or 3001) resistor from 36 pin of MFD board.

If you are the lucky owner of Passat B5, released for USA market, you have to add a few SMD resistors to the dashboard.

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

   
Attention!
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:

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.

  

2.9 Before assembly, check the functionality of the module in your car.

3. Assembly

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.

 

 

7. Next, you need to glue the matte protective film so that the display does not glare in the sun. Unfortunately, the film may not always be included, but it is easy to find on Marketplace, you can use a polyurethane matte screen protector for any smartphone just cut out with scissors to the right size. Product Reference 7. Далее нужно приклеить матовую защитную пленку, чтобы дисплей не бликовал на солнце. К сожалению пленка не всегда может быть в комплект, но ее легко найти на маркетплейсах, вы можете использовать полиуретановую матовую защитную пленку для экрана любого смартфона просто вырезав ножницами нужный размер.

Attention!
Be sure to stick the film!
Otherwise, the display may be damaged!

 

 

	4. IMMO 2  If you have a 1J0 comfort unit installed. Or your car is Seat Leon 1M. Be sure to stretch the wires from the comfort unit to the cluster. The comfort block 9 -> 8 pin of cluster`s outputs (CAN-H Comfort) of the green connector. The comfort block 6 -> 9 pin of cluster`s outputs  (CAN-L Comfort) of the green connector.

4.1 IMMO3 Cluster Installation in a vehicle with IMMO2
If you are installing IMMO 3 cluster in a car with 1J0 CCMS (comfort unit) — you shoul remove 2 resistors from the cluster board.
These resistors are coming from 8 and 9 pins of the green connector.

 

4.2 If you are Installating IMMO3 cluster in a vehicle with IMMO2,

you should activate the ambient temperature sensor in the cluster`s EEprom.

Passat B5 You need to change 1ef from 08 to 01 line 0001E0 column F

Golf 4 Cluster 1J0920806G no fis no show temp in dispay You need to change 1e5 from 2B to 2F line 0001E0 column 5

 

Change 2B in 2F and work

I changed that one 1E0 column 6 from 2B to 2F and it works

 

5. BOOST

To connect the boost pressure control, You need to add pin 15 to the green 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.

 

Most often,

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 B5 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.

6. ASSEMBLY

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. Choose in turn: tachometer, coolant temperature, fuel level and speed . The needles will make a turn on the whole scale, and then freeze. Remember or make a photo of difference in readings. Click «Done» and exit from the unit. Turn off ignition, remove the key and set the needles to correct position, turning them back counterclockwise.

	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 bucks! » =)
