Will Xhorse Super Chip XT57B Clone VAG MQB48 MQB49 Chip

Question:

Will Xhorse vvdi key tool max pro + XT57B super chip clone VAG MQB48 and MQB49 chips?

Answer:

No, XT57B cannot clone MQB48/49 chips.

XT57B supports MQB48 and MQB49 chip types. But they are not used for cloning MQB systems. They only be used to generate and program them.

NOTE:

The XT57B chip has region limitations. The global version cannot be used with Chinese version device, and vice versa. What we sell is the global version, which can only be used with global version key tools.

XT57B is compatible with mini key tool, key tool max, key tool max pro, key tool plus and key tool MIDI.

VVDI2 and old VVDI Key Tool cannot generate XT57B chip.

Xhorse Gen2 Red Remote Not Working Solution

 What Changed with the Xhorse Gen2 Red PCB Remote?

First, it’s important to understand the upgrade. The new Red PCB remote isn’t just a color change; it represents a significant internal overhaul:

• In-House Manufacturing: Previously, Xhorse purchased ICs (Integrated Circuits) from external suppliers for the Green PCB. The Red PCB features an IC designed and manufactured by Xhorse itself.
• Improved Performance: This change results in a higher operating frequency and, crucially, reduced battery consumption. The Red PCB remote will last longer on a standard 2032 battery compared to its Green predecessor.
• Dual Connectivity: While it retains the programming socket (for wired generation), it now also supports a wireless cloning/generation option, which is the source of both its convenience and the current user confusion.

Some users reported that the cloning function not working using the new red PCB remotes.

When attempting to clone a remote using the standard “Clone” function with a Red PCB, the process fails. This has led to frustration, as the Green PCB method no longer applies.

Solution

The fix is simple but requires following a specific path in the software. Here’s how to successfully clone to the new Red PCB remote:

What You’ll Need:

• Your Xhorse key tool (e.g., Key Tool Plus, Key Tool Max Pro, Mini Key Tool etc).
• The new Red PCB remote with a fresh 2032 battery installed. (The battery light should illuminate).
• original key

The Correct Procedure:

Enter Clone Mode: On your Xhorse device, navigate to the “Remote Clone” function- “HCS/Fixed Code Clone”.

Read the Original Remote: Follow the on-screen prompts to read the frequency and button data from the original remote. You will typically press buttons like Lock, Unlock, Trunk, etc., as instructed until the device captures the frequency (e.g., 314.98 MHz).

Hit the ‘Clone’ button.

CRITICAL STEP – Do Not Use “Normal Clone”: After reading the original, you will be prompted to place the new Red PCB remote to burn/clone the data.

DO NOT select the standard “Clone” or “Normal Clone” option here.

INSTEAD, you must select the “Wireless Generation” option (only support wire remote gen2).

Initiate the Burn: With the Red PCB remote (battery installed) placed on the device, simply press the Unlock button once. The device will now successfully write the data.

Verification: You should see a “Burn Success” or “Clone Complete” message. Test the newly cloned remote on your central locking tester or the vehicle to confirm Lock/Unlock functionality.

Key Takeaways for Professionals

• The Green PCB is being phased out. The Xhorse Red PCB Remote is the present and future for Xhorse remotes.
• The cloning process has changed. The wired socket is no longer necessary for this operation. Success depends on using the “Wireless Generation” sub-option during the clone process.
• Battery is mandatory. Unlike some wired programming, the Red PCB remote must have a battery connected for wireless cloning to work.

Xhorse VVDI2 BMW BDC2 Coding Unknown Version Solution

Problem:

Want to add a new key to BMW G31 BDC2 system with xhorse vvdi2 and BMW BDC2 adapter. but I can’t get past reading the code.
VVDI2 gave an error coding unknown version.

Solution:

Coding file is corrupt. Put it into the car and add coding file with your tool.

The car has a software version from 2021, but the coding data is missing, you can do your work normally, it has to be imported cafd manuel later, but that only works with a coding program, car missin cafd from S15A-21-11-560.

User report:

The problem has been solved and VVDI2 handled it very well. The problem was that the client arrived with corrupted CAFD data. Didn’t notice it at first. I put the BDC back in the car and fixed it via obd2 using the X-Diag program and Launch adapter. Then I went back to the previous steps and everything went smoothly.

I changed the BDC coding via OBD and the vvdi2 program accepted the new coding allowing me to program the new key.

VVDI2 VW Polo MQB R7F701401 Decode 5000 Error Solution

 Problem:

It’s a 2018 VW Polo MQB48 model with processor R7F701401.
I have the PCJ7991WT chip on the PCB, which finally confirms that it is the mqb49 5c.

Xhorse VVDI2 cannot decode data (read by multi prog) or change the mileage.

Solution:

It’s MQB49 cluster. Requires new MQB49 5C adapter set.
Only use the new MQB49 adapter, vvdi2 will decode data to change 5C/5D cluster mileage.

Use new MQB49 adapter and use this option to read cluster, than decode data with vvdi2.

Xhorse XM38 Toyota RAV4 No Proximity Function Solution

Problem:

Tried to generate 2011 Toyota RAV4 AKL proximity with Xhorse key tool max pro using XM38 Toyota smart key. Tried every option available for the 11 model and with some option I get no beeps and with some I get a single beep when adding new proximity after smartbox reset. Any solution?

If you have one beep it means that the transponder sets correctly but the proximity part of the key isn’t, you need your change frequencies in order to find the working one.

Possible solutions:

Solution 1:

RAV4 & Highlander generally share the same keys around that era.
In special functions/vvdi remote settings/toyota scan your XM38 & check the signal strength (0 is the strongest – 7 is weakest)
We’ve had cars with the right profile not detect because the signal strength was a 4, changed to 1 and went straight in with 2 beeps.

Solution 2:

Take out battery of xm38 after correct remote generation.
For some weird reason the double beeps on successful add, only happen with no battery in remote.
It’s counter intuitive as you usually just leave battery in to generate. Try it next time, it’ll work perfect. Have to do this on prox Toyotas only.
