How to Read Porsche BCM and Program Key with VVDI Tool

 

This article is about to compare different ways to read Porsche BCM and program keys by Xhorse Programmer. Some require de-soldering, while some don’t with certain cables and adapters.

 

Method 1. VVDI PROG (Desoldering required)

This way requires MC9S12 reflash cable included in the package and to desolder components (and to cut wires on part of chips).

1)Panamera (1L15Y) tested OK

It requires removing a component and soldering it back after reading and saving the FLASH file.

2)Macan (1N35H) & Cayenne GTS (5M48H) tested OK

It requires removing two components, cutting a wire, and soldering them back after it’s complete.

 

General procedure (VVDI PROG+VVDI2):

• Read&save D-FLASH file (VVDI PROG)>>Load the file (VVDI2)>>Program keys>>Install back BCM>>Learn keys via OBD (VVDI2)

 

Method 2. VVDI Programmer with Porsche Fast Easy Cable

This way requires Porsche Fast Easy Cable and wiring. No soldering is required.

This adapter works with VVDI PROG, VVDI2, and Key Tool Plus to read BCM without soldering.

1)1N35H tested OK

The rest procedure is similar to method 1.

 

Method 3. VVDI Key Tool Plus/Mini Prog with XDNPP017 Adapter

This way requires XDNPP017 Solder-free Adapter, so soldering is not required in this way as well.

1)Cayenne (5M48H) and Macan (1N35H) tested OK

 

 

General procedure:

• Read&save D-FLASH file (Key Tool Plus/Mini Prog)>>Load the file (Key Tool Plus)>>Program keys (Key Tool Plus)>>Install back BCM>>Learn keys via OBD (Key Tool Plus)

 

 

Alright, different methods require different adapters & cables and operation and watch the devices that adapters support.

How to downgrade ISTAP with Xhorse VVDI Prog +BIMTool

Here we’re trying to downgrade CAS3+ ISTAP. Because it’s encrypted since ISTAP upgrade and it doesn’t allow VVDI BIMTool or any software to write a key to it.

 

What we want to do is:

Write back the original FLASH data that was doing a key before.

Try to crank CAS3+ module by BIMTool and bench test platform.

 

Step 1

So, first we write the original FLASH into CAS3 by VVDI Prog Programmer.

 

Step 2

Set up bench test platform:

Connect the cable to all hardware (BIMTool, JBE, CAS3, key slot, switch…)

Notice the PIN on JBE module.

Insert the key and light on the cluster.

We see there is a steering lock but we can bring up the mileage. (The temper dot comes from the mismatch of the kilometer between CAS and cluster)

 

Step 3

We hook up BIMTool.

Turn to “CAS key learn” page and connect.

Click on “Get Key Info” and “Add key”.

If it’s encrypted, here it’ll prompt.

But, it asks if we’re going to update firmware, which means FLASH writing by VVDI Prog worked.

Now disconnect PC from the Internet.

Press “No” to update firmware.

Then press “Yes” to flash CAS firmware.

Follow the instruction and it gives us key info.

Finally we manage to crack and downgrade CAS3+ ISTAP on bench.

Try if it can give us ISN.

Exchange ECU/CAS>>CAS – CAS3+ OBDII>>Read ECU ISN

No.

Try it via EEPROM dump file that we got from VVDI Prog, and a working key.

Yes.

Done!

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 connect AUDI BCM2 Adapter with VVDI 2 & VVDI PROG

 

With VVDI PROG and VVDI BCM2 adapter, VVDI2 support:

1. 2013-2019 A4L /A5/Q5 add key and all key lost
2. 2013-2019 A6L /A7/A8 get BCM2 immo data while all key lost (Synchronize data can get from 3rd service provider)(Add key can get BCM2 immo data directly via OBDII)

What we want to do today:
Read and write Audi 5th Immobilizer System- Locked BCM2

Good to know:

• Warning 1 : This function is high risk, all the consequences caused are undertaken by yourself
• Warning 2: In VVDI-PROG function, Don’t touch power supply, cable, BCM2 module!!!

VVDI-PROG data instructions:

• DATA1: VVDI2 stepl require data, you can read DATA1 after connect in VVDI-PROG
• DATA2: VVDI2 step2 require data, you can read DATA2 after you get instructions in VVDI2(load DATA1 in stepl)
• SERVICE-DATA: you can get this data in step2. Write this data to BCM2 activate module
• DATA2-BACKUP: If read DATA2 failed(cause by power or cable), you can use this function to get DATA2 data

Instructions of using AUDI BCM2 Adapter with VVDI 2 & VVDI PROG:

• First use OBD Read Version function, OBD read BCM2 version and check support status
• Open trunk: Find the BCM2 in right-rear area, remove the two big plug, then small one(DON'T close trunk)
• Connect VVDI-PROG and BCM2 module, VVDI BCM2 adapter require support +12V
• Enter VVDI-PROG->immobilizer->Audi->LOCK_BCM2-1 orLOCK_BCM2-2 read DATA1 data and save it(Depends on the SW version)
• Enter WDI2 stepl, load DATA1 data(require internet), continue with VVDI2 instructions (maybe not need DATA2)
• If VVDI2 ask you provide DATA2, enter VVDI-PROG read DATA2 and save(After read DATA2, BCM2 will enter service mode)
• Enter VVDI2 step2, load DATA2 data(require internet), it will save 2 files: BCM2 immodata and BCM2 service data
• BCM2 immodata can use learn key, BCM2 service data can write to BCM2(make BCM2 work again) with VVDI PRO.
• After write BCM2 service data, restore BCM2 to car.
• Enter 5th immobizer system learn key.

Enjoy!
