How to Repair Benz W205 BMS with Xhorse VVDI prog

 This is the BMS (battery module) used on Mercedes C Class W205.

The battery is out of power.
So we need to repair the file using the xhorse vvdi prog programmer.
Put some soldering paste on it.

Use this hot air station to heat it until it reaches a certain temperature.
Then take it off with tweezers.

Be careful not to overhear when heating
Otherwise, the chip will be damaged.

There is a point on the chip shows PIN number 1.
According to the position we will know which direction to solder it on the adapter.
and match it to the small hole on the chip which shows PIN 1.

Then solder all, put some soldering paste.
Then connect the adapter with vvdi prog to read and write.

Run vvdi prog software
Select ST M95M01 chip

Read chip
Save chip
Then select the file to repair the BMS

Write chip

Write data successfully.

Reinstall chip back into battery module.

Xhorse VVDI Prog MQB NEC35XX Write Error 00?

Problem:

I’m trying to write Nec RENESAS V850 D70F3632 with xhorse vvdi prog after Erased and Unlocked. Config and P-flash writing with no problem, but D-flash I can’t write, give me Write Error (00). If I try to write an FF dump, all writing is good. I can change only the first 4bit, and write. Tool VVDI-prog. 5.3.2.
Does possible to write this Nec after unlocking?

Solution:

VVDI Prog can only read MQB NEC35XX RENESAS V850 D70Fxxxx mcu, cannot write mcu.

Same as RH850 mcu, vvdi key tool plus can only read, cannot write.

Program VW Passat B7 ID48 Key using VVDI2 and VVDI prog

 How to: program VW Passat B7 ID48 Key using Xhorse VVDI Prog+ VVDI2.

Here we have a working key so need to add a spare key. The easiest way is to clone ID48 transponder with vvdi mini key tool. Here we did it with vvdi prog and vvdi2 because have no id48 token. Same procedure if all keys lost.

Run VVDI2 software->VW->4th Immobilizer system- VW/Skoda/Seat->VW Passat/CC Key Learn

Select OBDII Read Login Code+ Part memory data

You can read engine ECU, get PIN, CS
Switch ignition OFF, then switch ON

security access failed, vvdi2 cannot read the login code for current ECU.

So we need to remove comfort module to read eeprom

Remove comfort module, read m95320 data with vvdi prog
Save original dump

Assemble the comfort module and install it back on the car.

Go to VVDI2 again
VVDI2->VW->4th Immobilzier system- VW/Skoda/Seat->VW Passat/CC Key Learn->Load Comfort Module EEPROM (95320)

Upload eeprom just saved

Select Get PIN, VIN and search 7 bytes CS from dump file

decrypt 95320 dump file

Find 7th byte success
Make dealer key with 7 bytes CS

Put new key into vvdi2 programmer

Make dealer key success

Input number of keys to learn: 2
Select Key Learning
Press OKAY button to start learning. Insert dealer key into car and switch it on for at least 2 seconds.
Then change next key within 5s.
Learn key successfully

New key will start key successfully.

You need to program the ID48 chip or the transponder separately.

The remote should be adapted separately.

Get the remote programmed by vcds cable.

Done.
