Two adapters are each equipped with two card slot fasteners.
There is also a cable connecting the interface board and the KD-X4, along with some fixing pillars used to secure the interface board and the BCM2 module.

Select the corresponding interface board based on the processor chip.
It is essential to choose the correct cboard.
Takes D70F3635 board as an example.

First, remove the two fasteners.

There are three holes on the back side of the BCM2 module.

Secure these three holes using the fixing pillars.

Align the three holes of the interface board with the three fixing pillars on the module.

Press the BCM2 interface board downward.
Continue installing the fixing pillars.
Then, fasten the board fasteners.
The shorter side should be on top, and the longer side should be at the bottom.




After installing the interface board, connect it to the KD-X4 device via the cable in the package.
Connect the KD-X4 to a mobile phone using an OTG cable, and use the app to operate the software and read data from the BCM2 module.

Xhorse Multi Prog Repair Porsche Cayenne 12V Lithium Battery

 How-to: repair Porsche Cayenne / Lamborghini Urus / Audi Q8 12V lithium battery with Xhorse Multi Prog programmer. Multi-prog has built-in algorithms that can directly repair modules.

Fault code DTC P1D6C00 – 12V lithium battery diagnostic system monitoring fault.

This error appears after a critical battery discharge. After the battery is discharged, the BMS module turns on protection.
There are 2 ways to solve the problem: buy a new battery or remove protection in DFLASH.

Repairing the battery is not a difficult task, the most difficult thing is to get to the BMS board.
The battery is located at the feet of the front right passenger.

We take out the battery and take it to the table for repair.
The BMS board is under the top battery cover. The cover is glued and you will have to tinker to remove it. You need to remove the side cover and unscrew the two battery terminals, then carefully remove the top cover.

To remove protection here we use multiprog, but it can be done with another programmer.

Multi Prog pinout to Porsche 12V battery module SPC5644B-ON32E.

Steps:
1) Read and back up DFLASH data.
2) Correct the file (click Renew and Repair)
3) Write it back
4) Before connecting, be sure to charge the battery; if you do not do this, you may get the protection triggered a second time.

Xhorse VW T6 2019 Car Starts Remote Not Working Solution

Problem 1:

VW Transporter T6 2019 add key mqb48 successful with xhorse vvdi key tool plus but remote not working. I try to add remote from 09 central control system but it’s fail straight away. Did use every single remote possible I did program about 7 different type of remote mqb ….the car start but the remote control not working also I do own VW transporter 2017.

Problem 2:

Add key Caddy 2019 – i generated the below vvdi MQB smart key and added using vvdi2 but cannot get my remote function to operate. Key starts fine. Only original remote working. Any advice?

Problem 3:

VW Caddy 2019 year successfully programmed new key and start engine but remote not work.

Here is the clue.

Everybody complains that problem is with 2019+ Transporter, Sharan, Caddy, Amarok, etc IMMO 4.5 system.

If 2019+ only dealer key and odis but if 2018 and down you can use Xhorse remote no problems.

Caddy use UDS system like the 5k0 AD remotes. From 2014 until 2018 it is UDS remote with MQB. You can generate 5k0 ad and use seperate id88 transponder.

After 2018+ the remote system is locked and only odis and dealer key can be added.

4.5th genaration IMMO key MQB48 2019 some cars need original key.

After 2018/7 months you must use chip on board key and only dealer key you can program online with ODIS after you program the chip the remote works directly.

Remote central locking channel is blocked 2018+. Need ODIS to open channel with dealer key and remote can be added then.

 

Solution 2:

If you don’t have OEM key, you need the right key, most of the aftermarket 5K0837202DH don’t have the chip on board but have a separate PCB for Transponder which after 2018 you can’t program remote as the Channel is locked.
Order key FCC BH will work xhorse not work on this module.
Can add with vvdi2 need BH part number, mqb key. After learn key remote automatically add.

 

Solution 3:

Did plenty and had same issue after program remote indicator flash but remote not working. You need to flash Bcm with same firmware or highier and that will fix issue.

Yanhua ACDP BMW BDC2 All Keys Lost Warning

 While Yanhua Mini ACDP supports BMW BDC2 all-key-lost functionality, there are still critical considerations.

Here are the risk warnings.

1. This All-Key-Lost function is only an emergency solution and will affect the BMW Dealer service. Please consider and note this before use.

2. This All-Key-Lost function will change the original vehicle IMMO info. If you want to restore original vehicle IMMO info in the future, you need to order a new key from BMW Dealer. Then restore the IMMO info with ACDP assistance.

3. This All-Key-Lost function does not work on BDC2 electric and hybrid cars.

 

4. It does not change the ISN, it changes the eeprom. It resets bdc2, ecu and tcu. Issue is that if you do akl this way, owner will sell car, new owner would like to buy key from dealer, that official key will never work on car after acdp akl solution.

 

5. When performing All Keys Lost with ACDP the BDC2 will be locked. Keys bought from the dealer will not work and unless you are the original one that made a key no new keys can be added unless you contact ACDP and get them to restore the modules.

 

 

 

ACDP won’t accept any dealer key after this procedure. If the owner wants to order a key from BMW dealer, it cannot be used either.

Unless contact ACDP to restore the modules.

The AKL procedure must be done by ACDP to restore the original dealer key.

Recovery process after getting the dealer key:

Step 1: Read the BDC2 key

Step 2: Read the dealer key’s IMMO data

Step 3: Write the dealer key’s IMMO data back to the BDC2.

Step 4: Get in the car and program the dealer key (the ignition must be able to turn on)

Step 5: Write the DME ISN (the car can be started)

Step 7: Clear the transmission
