What is the advantage of Yanhua Module 29?

OBD identification function can know whether the vehicle supports OBD to read IMMO data, whether the BCM2 type is encrypted version, and whether the BCM2 module needs to be removed to read IMMO data.
Special interface board to read BCM2 IMMO data, pin intelligent detection, data read and write safe and reliable.

How to use Yanhua Audi Gen5 BCM2 IMMO Module?

Connection:

For BCM2-A interface board:

Step 1. Prepare ACDP, OBP+ICP adapter, BCM2-A interface board and BCM2 module.

Step 2. Locate the D1, D2, D3 anchors on the BCM2 module.

Step 3. Locate the probe test point location on the BCM2 module.

Step 4. Install the interface board fixing studs.

Step 5. Install BCM2-A interface board based on the registration point D1/D2/D3.

Step 6. Lock the studs and clamp the PCB lock.

Step 7. Short the jumper cap to "CAN-R-NC" port according to the marked position.

Step 8. Connect ACDP, OBP+ICP adapter, BCM2-A interface board and BCM2 module.

For BCM2-B interface board:

Mini ACDP APP Menu Path:

VW>> Audi 5th BCM2 IMMO>> Step 1: OBD Identify>> Step 2: Get BCM2 IMMO data>> Step 3: Make dealer key>> Step 4: OBD learn key

Besides, you also can perform special function.

Detailed operation process:

Step 1: OBD Identify

Tap read vehicle info to start

Notes:

Connect ACDP to vehicle OBDII, and it is forbidden to power off or unplug the device during operation!
If have working key, please insert to/near ignition switch and light the meter.
If all key lost, please open the car headlight and press the brake for several times!

Step 2: Get BCM2 IMMO data

1.OBD read IMMO data

Tap Start read data

Notes:

Connect ACDP to vehicle OBDII, and it is forbidden to power off or unplug the device during operation!
If have working key, please insert to/near ignition switch and light the meter.
If the working key is already in car, take out and insert in again (also switch START/STOP button).
If all key lost, open the car headlight and step on the brake.
If ACDP prompts that the BCM2 module needs to be powered off, disassemble/install the BCM2 module connector according to the illustration!

2.ICP Read IMMO data- BCM2 not encrypted

Select the corresponding BCM2 chip models below:

BCM2 (D70F3381)

BCM2 (D70F3382)

BCM2 (D70F3634)

BCM2 (D70F3635)

Notes:

Confirm BCM2 chip model, this feature is suitable for unencrypted BCM2 module read IMMO data, DFLASH and PFLASH.
Disassemble/install the BCM2 module connector according to the illustration, don't close the trunk!

Read IMMO data

Read chip data:

Read DFLASH data
Read PFLASH data
Write DFLASH data
Write PFLASH data

3.ICP Read IMMO data- BCM2 encrypted

Select the corresponding BCM2 chip models below:

A4L/A5/Q5 2014- add key or lost all key (All version)

A6L/A7/A8 2015- Lost all key (0824/0825/0827)

A6L/A7/A8 2015- Lost all key (0510/0521/0551/0560/0572/0582)

Pay attention to the note for every BCM chip

1.This feature is risky, all consequences are borne by the user.

2.Forbidden to move the module and harness and power supply during operation, don't close the trunk and keep the network connect.

For A4L/A5/Q5:

It is suitable for A4L/A5/Q5 key add and all key lost to read BCM2 IMMO data after 2013 (all key lost don't need to sync data).

Such models don't support OBD direct read BCM2 IMMO data, and BCM2 is locked and don't support programmer direct reading.

For A6L/A7/A8:

It is suitable for A6L/A7/A8 all key lost to read BCM2 IMMO data after 2013 (sync data needs to contact a third party).

Such models key add support for OBD to read BCM2 IMMO data, and don't perform this function.

Read IMMO data (Automatic)

Read IMMO data (Single step):

Step 1: Read BCM2 CONF data

Step 2: Online make IMMO/serve data

Step 3: Write BCM2 serve data

Step 3: Make dealer key

A4L/A5/Q5 2014- add key or lost all key- Don’t need working key

A6L/A7/A8 Touareg add key- Must have a working key

A6L/A7/A8/Touareg lost all key- should have the sync data

Notes:

1.Prepare the BCM2 IMMO data obtained in the step 2, and then put the blank key into the BAV-KEY adapter.

2.When the A4L/A5/Q5 add key or lost all key, make the dealer key don't need working key.

When the A6L/A7/A8/Touareg add key, make the dealer key need to get sync data from the working key.

When the A6L/A7/A8/Touareg lost all key, make the dealer key need to get sync data from a third party.

Step 4: OBD learn key

Tap Start learn key

Notes:

Connect ACDP to vehicle OBDII correctly, and don't cut the power nor pull out the device during the operation.
Prepare all the keys of the current car, the unlearned keys will not be able to start the car.
Insert the key to be learned into the ignition switch in turn, and when successfully learn a key, the X of X/Y in the instrument screen will be added by 1.
If there is only an induction coil, need to close and open the start button after each key learned.
All operations of learning the key should be completed within two minutes.
