How to use VVDI Prog to Enable paid options by Tesla for Free such like free supercharging , free FSD and much more.

This method cannot be changed by Tesla.
Once you change config by this way, the car is 100% continue work with all updates.
After changes have been made to the dump and written to the car, you should write correction to save the changes from update.

Solder and bridge the following resistor on the board of MCU2 Intel.

Xhorse VVDI2 MQB49 5C IMMO Error Code 5000

 Problem:

I managed to read this dash VW Crafter 2019 MQB49/5C and saved the dump by Xhorse Multiprog, but when I load it to VVDI2 it can not decode immodata. I want to add a key to the car.
Any idea where is the problem?

Solution:

Only 5A cluster for immo data decoding
5C only for KM. Cannot do immo data.
Mqb 49 is not decoded by any machine.

VVI2 will add key MQB 49 5C but still need to get sync data. It cannot do MQB 49 5C all keys lost.

BMW CAS4 FEM BDC Coding Lost VVDI BIMTool Pro Solution

This is a tutorial on how to solve BMW CAS/FEM/BDC version & coding loss issue with Xhorse VVDI BIMTool Pro. You can refer to the solution in this article if you’ve met the following problems:

• BMW CAS4+ and FEM/BDC OBD show unsupported versions and require upgrades.
• BMW CAS4+ and FEM/BDC OBD preprocessing completes but indicates coding loss with no recovery possible.
• BMW OBD preprocessing is unexpectedly interrupted due to missing SWFL version, halting further processing.
• The vehicle’s SWFL or coding version mismatch causes functional deficiencies.

Solution

Here’s taking FEM module as an example.

When the SWFL, CANFD coding and key position info are missing, we can resolve these issues using BIM TOOL or BIMTool Pro.

1. Connecting Tools

Connect VVDI BIM TOOL, then open software, select

Fxx/Gxx Program/Code >> Auto detect >> Connect car

2. Calculating Programming Files

Vehicle programming >> 40-FEM[FEM_BODY] >> Calculate Programming File

Detected programming file which calculated success for this vehicle.

Press YES to load the calculated programming file directly.

Press NO to calculate the programming file again.

Calculate programming file require 1-5 minutes.

Click YES.

Noted the “Target istufen lev” should be the same as the “Shipment date”.

3. Programming

The gray area indicates the module’s current version information.

The orange area indicates the calculated programmable version information.

Click “Programming” to proceed.

Note: After programming is completed, read the vehicle’s DTCs and clear them.

4. Key Learning

After clearing the DTCs, process “FEM/BDC Key Learn >> Get Key Info”.

You can see the coding and key position info have been restored.

Xhorse Multi Prog Read ECU via OBD?

 Some users asked what the Xhorse Multi Prog OBD cable in the package is used for.

The OBD cable connects multi-prog with vehicle via OBD connector to read ECU by OBD.

Multi-prog supports some ECU reading/writing via OBD.

No specific ECU list is available.

Just check multi-prog software, see if there is OBD mode option.

If yes, connect multi prog with vehicle via OBD cable.
