VVDI MLB Tool MQB48 No Result in Server Solution

 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.

Xhorse VVDI PROG Read Hyundai XC2361A-72F Airbag

 Here are the Hyundai Verna airbag modules. As you can see, the second module we have made connection to the Xhorse VVDI PROG. Following we’re gonna read the airbag data for module reset.

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.
