How to distinguish whether Audi BCM is an encryption Type

 

Recently released Xhorse BCM2 Solder-free Adapter allows users to read encrypted Audi BCM2 module, but how to know if it’s a locked version? In this article we’ll raise two ways:

1. Judge by the number on BCM2 module
2. Read BCM2 info by VVDI2/Key Tool Plus

 

Generally, BCM2 modules before 2013 are unencrypted while those after 2013 are encrypted.

However, there are exceptions after 2013 and it’s hard to judge 2013 versions.

Then we have

Method 1. Judge by the number on the BCM2 module

After we remove a BCM2 module, check the number on the box. (Here we have “0711”)

On the chip selection page of VVDI PROG or VVDI Key Tool Plus, supported numbers are listed on the below.

If our BCM2 number is on the list, we need to read it by an encrypted BCM2 Adapter.

Notes:

1)VVDI PROG has “LOCK_BCM2-1(ADAPTER)” and “LOCK_BCM2-2(ADAPTER)”

2)For our “0711”, we should select “(all versions)” on Key Tool Plus.

If we cannot find a number on our BCM2 modules, remove the cover to check the number on the chip of the circuit board.

Then see if our number is listed on unencrypted versions.

If so, read it by the selection prompt (our “3634” is unencrypted and it can be read in a soldering/solder-free way);

If not, Do Not Try to read a unknown-version BCM2 and contact your dealer to confirm.

 

Method 2. Read BCM2 info by VVDI2/Key Tool Plus

Sometimes we find part of BCM2 modules on the encrypted list are unencrypted, so we have the second way - OBD identify/read.

Before We Remove A BCM2 From A Vehicle, connect VVDI2/Key Tool Plus to your vehicle via OBD to check.

Path 1 (on VVDI2):

• Key Learn>>Fifth Immobilizer-Locked BCM2 version

Path 2 (on Key Tool Plus):

• Immo Programming>>Audi>>Select by type>>Fifth Immobilizer System>>Start Programming>>Read BCM2 Data>>OBD identify BCM2 type

It’s accurate to read BCM info via OBD, and then follow the instruction:

For unencrypted versions, read D-FLASH and P-FLASH without encrypted BCM2 adapters.

For encrypted versions, Do use encrypted BCM2 adapters.

 

Other tips

1. When we read an encrypted BCM2 with VVDI AUDI BCM2 adapters, Do Not click on “Unlock”, or the module will be erased and no way to restore.

2. During removing BCM modules or soldering cables to BCM circuit boards (Particularly in winter), Do care static electricity, which may cause damages to chips or data loss.

 

Alright, that’s how we identify BCM2 status and some tips during operation.

How to disassemble Xhorse VVDI Key Tool Plus

Today xhorsevvdi is going to share with you how to take out PCB Board inside VVDI Key Tool Plus.



Let’s start it, easy and simple.

1. Remove 12 screws on the back. (8 surrounded, 4 on the center)


2. Make the front side up and remove the front cover. (note: watch the cable connected to the screen)


3. Disconnect 3 ribbon cables.


4. Remove the thin cable as shown.


5. Unscrew 4 screws on the PCB board.


6. Take out PCB board and disconnect battery cable.




Finished, that’s the process of taking out PCB board from Key Tool Plus Pad.

How to Fix VVDI Key Tool Plus Error Code: 13040031 with BCM2 Adapter?

During the process of using Xhorse Audi BCM2 Adapter to read & write data with VVDI Key Tool Plus and VVDI Prog, some may have error reports or failure messages. In this article, We will put together 2 errors and solutions for your reference.

 

Issue 1.

Read DATA1 success with BCM2 adapter , but during DATA2 reading VVDI Key Tool Plus prompts “Error Code: 13040031”and“Read Data fail”.

 

Solution 1 :

Do Not try as you like when it shows “Error Code: 13040031”, the correct way is to check cables & adapters connection and external power supply, try to read again and it should be fine (Do Not read DATA1 again, unlock BCM or try to install BCM back and read via OBD). Read data as instructions and restore BCM back, and there will be no other problems.

 

Issue 2.

Read DATA1 and DATA2 success, save Immo data and service data success, but write service data fail and it prompts “Fail to erase” when repeating service data writing. Try again and DATA1 reading also fails.

 

Solution 2 :

When VVDI PROG  reads DATA1 & DATA2 successfully and saves service data, we can select “Unlock” to unlock BCM’s CPU.

Until the system prompts that the unlock is successful

Then select “SERVICE DATA” and write it back.

After writing successfully, restore BCM back to vehicle, and vehicle can start without additional operation.

 

Above problems are collected from customers feedback. Hope this could help. More questions, contact us.

How to read locked BCM2 with Xhorse VVDI Key Tool Plus

 

How to use Xhorse AUDI BCM2 adapter with VVDI Key Tool Plus ,no need solder

Prepare:

1. VVDI Audi BCM2 Solder Free Adapter
2. VVDI Key Tool Plus
3. Network connection

Operation mainly includes:

• Step 1. Read basic module information
• Step 2. Read Immo data
• Step 3. Write Immo data

Note: Make sure Key Tool Plus is connected to network and adapter is supplied 12V power.

Procedure:

• Immo programming>>Audi>>Select by type>>Fifth Immobilizer System>>Start Programming

On system menu,
Select

• Read BCM2 Data>>Prog read – encrypted bcm2

Select vehicle type by the label on BCM2.
Here we select “

• A4L/Q5 2014- key adding and all keys lost (all versions)>>Adapter method”.

Then watch “Function introduction” and “Connection diagram” carefully.

Perform “Step 1 – Identify module information”.
Finish connection by diagrams, and care
Positions of D1, D2, GND.


Click on “Read” to get basic information.


Perform “Step 2 – Read immo data”
Confirm vehicle info we just get and
Click on “Read” to get BCM2 Immo data.

Then we go on to write it back to BCM2 module.


Now we can restore BCM2 module to vehicle and generate dealer key on Fifth immo system menu.
Done!
