Question: Is it possible to generate MQB48 transponder from xt27A or xt27B vvdi super chip to be used in VW cars post-2018 to star the car? Pic is from Xhorse VVDI Key Tool Max Pro.
Solution:
Xt27b is on available in the b5 remote version. You won’t find the transponders alone.
At the moment xt27b are inplemented on board XHORSE XEB510EN B5 Super Remote with XT27B Super Chip. Or buy XHORSE XT1M Chip they are MQB Chips.
They have XT27B chip inside.
If you have a Tire Pressure Monitor malfunction DTC error after programming BMW 4D/8A motorcycle keys with VVDI Key Tool Plus or VVDI2, here is the working solution.
The problem can be solved by VVDI BIM Tool or VVDI BIMTool Pro programmer.
Connect BIMTool pro with laptop and motorcycle.
Run VVDI BMW software.
Go to “Program/Code” function.
Auto detect and connect Car to retrieve vehicle information.
Select Vehicle Programming.
Make sure “target istufen lev” is the same as the “Shipment date”.
If there is no shipment date available, choose the latest one.
Click on “FEM” and press “Calculate programming file”, press Yes to confirm
The calculation is completed.
Gray areas indicate the current module version information.
Orange areas indicate the programmable version information.
Click Programming to proceed.
Auto input VIN code.
Programming finished.
After programming is completed. Read and clear DTCs.
No DTC display on BMW motorcycle dashboard.
Done.
Problem:
Failed to update xhorse vvdi mini key tool firmware via app and via upgrade kit on PC.
When update firmware via app, it reported error “Erase the internal chip 1 fail”.
Here is the VVDISHOP engineer solution:
1. Turn off device.
2. There is a small hole on the back of the device case. There is a button inside, press the button with a toothpick, then hold the power button.
3. Turn on device, then try to update firmware again, it should be fine.
Question:
Can I generate a chip control for a 2016 Chevrolet Beat with xhorse vvdi key tool max and vvdi super chip? Is a 4A chip.
Answer:
Yes you can generate GM 4A chip with super chip, but need super chip XT27B not XT27A.
You can do 4A with Xhorse B5 Super XT27B Universal Remote Key 3 Button – XEB510EN.
Here comes the similar problem:
BMW F30 after desoldering 95128 eeprom all data lost (maybe overheated). Using xhorse vvdi prog and vvdi2.
In new eeprom i wrote data from another FEM but car now starts only from the emergency coil, remote did not works.
i try wrote many dumps from another fem. update FEM with ISTA , but remote still not working.
Tried to desolder with hot air, the eeprom may have been damaged.
Is it possible to restore data? What is the procedure to recover the FEM? Or do I need to buy new FEM?
Solution:
NO NEED TO BUY ANY NEW FEM.
Find any 95128 dump make all programming FEM with vvdi2.
Restore coding
Now in car key must start only from the emergency coil.
next
At first read isn by vvdi from the working key.
Erase key with vvdi.
Dissemble key.
Renew key by vvdi key tool or vvdi prog.
Program “old” -new key with vvdi2.
Also if it is manual gearbox you will need to virginize the elv.
AND ALL !!!!
You can also restore FEM with autohex, same procedure as above.
For the guys wondering why when a FEM flash fails you cannot fix it.
FEM has 2x SWFL, they control the ignition, if both SWFL become corrupted then the FEM does.
not know when and how to cycle the ignition, this is why you hear the relays clicking, if the bootloader is ok you may be able to restore the SWFL by updating istep, if the BTLD is corrupted then its likely a new FEM
if only 1 SWFL is corrupted and the other is ok then the FEM can be restored.
You also have other ways to program BMW FEM key, via clip solder free adapter or with bench test platform.
For example:
Program BMW F30 FEM All Keys Lost via Godiag
User feedback:
Car worked after writing file to new eeprom. Vvdi2 also let me correct the mileage.
Xhorse VVDI Key Tool Plus Program BMW F30 FEM All Keys Lost via Godiag FEM/BDC test platform successfully.
You cannot do it via obd fem. You opened fem module to read and write eeprom files.
You can do bench via godiag test platform.
Procedure:
1.Backup coding
2.Service mode, read eeprom data, load eeeprom and prepare service EEPROM, write service
EEPROM data, restore FEM/BDC shell, provide 12V+ and connect OBD.
3.Unlock FEM
4. Write back EEPROM
5. Recovery coding
If you read the warning it says if obd pre processing you can ignore that.

Problem:
Tried to read MQB 3525 cluster with vvdi key tool plus and MQB solder free adapter, but kept showing error ‘chip crack failed’. Any solution?
Solution:
If had a chip crack failed error when using xhorse MQB adapters, do a test 57 (Other/Test Function 57).
If 57 test function is ok, the MQB adapter is fine. Double check the connection and don’t forget to give power to mqb adapter. Subscribe our youtube channel and check video instructions.
If 57 test function is not ok, there maybe something wrong with the adapter. Take a video and send it to your dealer for analysis.
