Tag: VVDI MLB Tool

Problem:

I just got the mqb48 adapter for the Xhorse VVDI MLB Tool and it is showing up this error. It is updated, both USB cables connected. 2 different laptops and still have the same problem. I replaced the eeprom that came with it.

Error
“The current power supply quality is critically power, making it impossible to collect valid data.

 

 

 

 

Solution:

Follow the images below to use USB directly from pc.

Voltage 5V, Current not exceeding 0.5A.

The MQB48 adapter can only be plugged into a computer or key tool plus via USB. PC is recommended.

Also double check the wiring diagram, if everything is fine but still cannot collect data, download software here

Put it in the installation directory. Double-click to open it directly and try again.

Problem:

I recently purchased vvdi key tool plus and VVDI MLB Tool, I have had mini key tool and key tool max for some time. I combined these devices on the same Xhorse account. Today, when I wanted to read MLB’s conclusion, it gave me this message, “Failed to Parse server file ”

 

 

 

Solution:

You need to bind the MLB programmer to the device you will use it with, in this case key tool plus. It is not just plug and play. The MLB programmer should be shown on the tablet as a combined device in the combined devices section.

Updated:

FIRST TIME YOU NEED TO BIND MLB DEVICE. IT WORKS NOW.

Problem:

Had a problem calculating immo data with Xhorse VVDI MLB Tool and MQB48 adapter.

Error: “Failed to query last calculation result. There’s no result in server.” Any idea?

 

 

 

Solution:

Do not check ‘Query last successful reset’ option.

Hit Collect key data to calculate immo data again.

NOTE:

Removing the wrong capacitor can cause the MQB chip to become unrecognizable, making it impossible to collect data.
After reading the data, the capacitor must be restored; otherwise, the key cannot be programmed to car.

Here we will show how to calculate VAG MQB48 NEC35XX immo data with Xhorse VVDI MLB Tool and MQB48 adapter.

 

Model example: Audi Q2.

Tools used:

VVDI MLB Tool

MQB48 adapter

Original key

A new key to be programmed

 

 

Before using MQB48 adapter, we should modify MLB tool firmware as following:

How to Update VVDI MLB Tool Firmware to Use MQB48 Adapter?

Then we start to read immo data with MLB tool.

Run VVDI MLB Tool software. Choose MQB48 function and check wiring diagram.

Select corresponding wiring diagram. Here the key board is the same as type 5.

Need to solder 2 wires, black wire and red wire.
Remove a capacitor, the solder the red wire (near the IC position).

Open the original key shell.

Remove a capacitor as shown in the wiring. Then solder two wires.

 

 

Connect Xhorse XDMQBAGL MQB48 Adapter with MLB Tool.

Connect Key board with MQB48 adapter. Place the key to coil of MQB48 adapter in the vertical direction.

The MQB48 adapter has strict power supply requirements during data collection. Use two separate USB cables to power the MLB main unit and the MQB48 collector. Do not use charging adapters.
The MLB main unit does not require 12V power.

Then connect MLB Tool with PC via USB cable.

Read key information. Read Key ID successfully.

Press Collect Key data.

Collecting key data and calculating immo data.

Calculation finished. Restore key back to original status. Save MQB NEC35XX immo data.

Data Collection Time:
Good power supply: ~15 minutes for data collection, ~1 minute for immobilizer data calculation.
Average power supply: ~30–60 minutes for data collection, ~1 minute for calculation.

 

 

 

 

Resolder the capacitor back to the key. Reinstall key shell. This is very important !!!

 

NOTE:

Removing the wrong capacitor can cause the MQB chip to become unrecognizable, making it impossible to collect data.
After reading the data, the capacitor must be restored; otherwise, the key cannot be programmed to car.

 

If need to connect MLB tool with key tool plus to calculate MQB48 immo date, make connection like this:

Note: Tablets with a single Type-C port have poor power stability, leading to longer collection times and lower success rates. Strongly recommend using a PC.

Connect VVDI2 or VVDI Key Tool Plus with vehicle via OBD connector.
Go to MQB anti-system system (NEC35XX Continental/VDO), read cluster info.
Load immo data saved by MLB Tool.
Then generate dealer key and learn key.

Question:

Is it possible to reuse an Audi MLB key fob. Xhorse vvdi key tool plus has these options. Can we read key with VVDI MLB Tool and reset the key fob to a new state? What option… Recover the key / Upgrade OEM keys? Any idea?

 

Xhorse VVDI MLB Tool updated MQB48 NEC35XX immo data collection function recently. Follow the steps below to update your VVDI MLB Tool firmware to use MQB48 adapter.

 

The MQB48 adapter comes with solder wires and an enhanced version replacement chip.

Remove 4 screws on the back of the MLB tool and open the shell.

Remove 2 screws on the main board and check out the other side.

This is the front of the main board.

Replace this chip using the enhanced replacement chip in the package.

After replacing the chip, reinstall the VVDI MLB Tool.

Then you can use the MQB48 adapter to collect immo data.

NOTE: Both the device and the adapter need to be connected to a power supply !!!

By using with Xhorse VVDI MLB Tool, we can get the synchro, CS & Pin from the original key for backup. After successful MLB data collection and calculation, this data is available after the dealer key was generated. Detailed steps are as follows:

 

Step1. Identifiaction Key

Please place the key in the device identification area for identification.

 

Step2. Collect Key Data

Open the original car key, connect the original car key PCB as shown in the diagram, and click the collect key data button after connection. It will take about 3-4 minutes. The server takes approximately 10s to calculate. After the calculation is completed, please save the calculation results.

 

Step3. Make Dealer Key

Load the calculation data saved in the step2 and generate dealer keys. Then use VVDI2 or KEY TOOL PLUS for key learning.

Run VVDI2 software and select correspoding vehicle software, i.e Audi
Select Key Learn->MLB Immobilizer System.

 

 

 

Upload data read by MLB tool. Then you will get CS and PIN.

Today I finally have the chance to program a new key for Porsche Cayenne 9YA E3 with Xhorse VVDI MLB Tool + VVDI2. I have the original key and a 4-button key available. Fortunately, the key was workable.

 

Here’s how I do it:

1. Connect original key to VVDI MLB Tool.

 

 

2. Collect immo data from original key to generate dealer key.

 

3. Place keys in the slot betwwen the cup holders to program them to the vehicle.

 

4. Set desired key count. In this case it is 2.

 

Programming the second new key successfully.

2020 Audi Q8 Add Key with Xhorse VVDI MLB Tool and VVDI2 successfully!

Calculate and generate key data with MLB Tool, then learn key with vvdi2.

You have to remove capacitors.

On xhorse need only desolder 2 x capcitors. Nothing big work. On KYDZ you also need desolder capacitors.

Both tools require capacitors to be removed, the “solder less” adapters are only for the three wires you connect at the end which is the easiest part of the process.

The key cover shell is sealed, better to change shell.
