Keydiy KD-X6: Read MQB48 Key Data Directly – No External Device Needed

A significant upgrade of the Keydiy KD-X6 key programming tablet is the integration of MQB48 and MLB functions. Our customers have tested the built-in features and provided us with positive feedback, and we are pleased to share this with you.

 

Model example: 2019 Audi Q3

Transponder: MQB / ID48 chip

 

Disassemble original MQB48 key.

Turn on KD-X6 tablet.

Go to IMMO Programming- MLB/MQB48 function- MQB48.

Check key wiring diagrams and find the correct one that matches your original key circuit board.

Follow diagram to solder wires to the key circuit board. Need to remove a capacitor carefully.

Then read MQB48 key data.

Calculate key data in 5 minutes; not very fast, but very stable.

Restore the capacitor on the key circuit board after the data reading is finished.

Then generate dealer key and learn key following the KD-X6 prompts. The key learning procesure is the same as KD-X4.

 

 

Cheapest Way to Unlock VAG SFD Gateway

What’s the most cost-effective solution for VAG SFD security gateway unlocking?

 

We would like to recommend a few more budget-friendly options.

1). OBD Eleven 

Unlocking SFD (Vehicle Diagnostic Protection) itself is free once you have a qualifying account, but you need at least the PRO plan (€59.99/year) or ULTIMATE plan (€189.99/year) to use the manual coding and SFD unlock features.

 

There is no extra cost for unlocking SFD.

SFD Unlock Function: €0.00 (No extra cost per unlock, tokens, or GeKo account required).

Required Plan: Available on the OBDeleven PRO Plan (€59.99/yr) or ULTIMATE Plan (€189.99/yr).

One-Click Apps (Alternative): If you use pre-made One-Click Apps instead of manual coding to change settings, you do not need a PRO plan; you only need Credits (micro-currency), though running them still goes through the underlying SFD server request.

2). Autel SFD unlock annual subscription 

Autel has two ways to unlock SFD: 1 token ($15 for a 90-minute SFD unlock, not the cheapest) or an annual token subscription.

Pay the 115$ to Autel for a year subscription and unlock as many vehicles as needed.

Check supported Autel devices and detailed info here:

How to Online Unlock VAG SFD with Autel MaxiSys (Purchase Tokens in Device)?

Most scan tools can unlock SFD, the yearly subscription unlock is the best option if you’re doing them regularly.

TOPDON and LAUNCH X431 also have one-year SFD unlocking authorization, but they cost much more than AUTEL’s.

Topdon’s 1 year SFD access is $229 and Launch X431 is more complex [European users must get SGW bundle package $1,151; Japan, South Korea, New Zealand, Australia: 299USD; Other Asian countries: 199USD.].

There are also some other devices that support SFD unlocking, i.e Xhorse, Keydiy, but they charge on a per-use basis, which is not cheap in the long run.

 

Please be aware that this refers to the SFD1 unlocking solution, not SFD2.

Yanhua ACDP BMW BDC 085 Lost Coding Solution

Problem:

Tried to add a spare BMW BDC 085 version key with Yanhua ACDP2 but failed. It says “usb line is poll out” and coding was lost.

14V stable power supply.
Not touched anything during preprocessing.

Any solution?

Solution:

You can restore it with ACDP itself.

If does not work error “Restoring Coding data failed, please use BMW ESYS to restore the Coding data”, follow the suggestion and restore data with E-sys.

 

User report:

1). Restored (remotely) with esys and added key on bench.

2).

I had the same issue with a BDC in two different occasions.
I ended up restoring data with Vvdi bim tool.

With the latest Flex update, version 8.17.0.0, Mercedes Bosch ECUs equipped with SPC5777 processors are now supported via Korhex and the EMFI – Electromagnetic Fault Injection technology.

This procedure simplifies access to the unit: no need solder the PCB nor to remove components.

Less steps, more autonomy in your workshop.

Place Korhex, follow the Flex-guided procedure and access the SPC5777 microprocessor.

To perform these operations, you need the FLS0.20 license or the Flex Full FLS0.5 configuration.

Can we unlock without korhex ?
This processor requires the use of Korhex.

 

No soldering method?
No, no desoldering.

 

KESS3 Supported Boot Glitch Unlock ECU List

KESS3 expands the range of operations available on the latest “Locked” Bosch MDG1 ECUs and introduces a new dedicated accessory: the KESS3 Unlock Module.

With the new Alientech KESS3 Unlock Module, you can perform the Unlock procedure directly in your workshop on supported Bosch MDG1 ECUs and then access their memories in BOOT mode.

 

This new accessory is specifically designed to perform the “Unlock” procedure directly in the workshop on MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 (HW80), MG1CS031, MD1CP006, MD1CS005 and MG1CS002 ECUs. Once the unlock is complete, the ECU can then be programmed in BOOT mode, accessing its memories to perform reading, writing and a complete backup of the contents.

 

This update expands coverage across a wide range of diesel and petrol applications equipped with protected ECUs, produced from 2021 to the present day: from commercial vehicles to high-performance cars and SUVs.

The benefits for everyday workshop operations:

• Unlock protected ECUs directly in the workshop
• KESS3 Unlock Module dedicated to managing the BOOT “Unlock” procedure on supported ECUs
• Access to ECU memories after the Unlock procedure
• Reading and writing in BOOT mode
• Complete backup of ECU contents
• Greater coverage of multi-brand diesel and petrol applications
• New opportunities to work on commercial vehicles, cars and high-performance SUVs

With KESS3 Unlock Module and KESS3, you can manage the entire operation directly in the workshop, maintaining control over every stage of the process: from the initial ECU unlock to memory access and subsequent programming in BOOT mode.

The new protocols are available to KESS3 users with CAR BENCH/BOOT activation and an active subscription. The KESS3 Unlock Module is required to perform the BOOT “Unlock” procedure.

Solve Land Rover P400 BECM BMS Fault Code P0AA0-66

Here comes the solution for Land Rover P400 BECM BMS hybrid battery module fault code P0AA066.

 

Fault Code P0AA066:
Fault code P0AA0-66 in Land Rover and Range Rover hybrid (PHEV) vehicles means “HV/EV battery positive contactor circuit – signal has too many transitions/events,” indicating the Battery Energy Control Module (BECM) refuses to close the high-voltage safety contactors because internal counters or signals exceeded their safe limits.

Root case:
Internal BECM Chip Failure: Corrupted data or physical wear on an internal chip (such as the TC264 processor) inside the battery management unit.

Contactor Cycle Overflow: The module records “positive contactor switching cycles exceeded” due to false or excessive signal transitions.

 

Repair Solution:

Full Unit Replacement: Dealerships typically want to replace the entire high-voltage battery pack or BECM unit at a very high cost.

Component-Level Repair: Specialized auto-electric workshops can fix this without replacing the whole battery by replacing and reprogramming the specific faulty processor chip on the BECM board.

1). Replace with a brand new MCU chip.

2). Reflash data to the new MCU chip with proper programmers (such as JLR Pluto, Launch X431 PAD VII).
