Attempted a VAG DQ500 (OBH) gearbox mileage correction using a Yanhua Mini ACDP2 and module 30. The process failed—the ACDP app reported a gearbox communication error. Furthermore, the module voltage dropped rapidly despite using an external power supply.

How to Solve Autel iKey Toyota 4D8A Low-Freq Key Error?
Problem:
This is Lexus RX350H 2023 all keys lost.
Tried to generate an Autel Toyota ikey with Autel IM608.
But the Autel device says it is wrong key and asks to use Toyota 4D8A low-frequency universal key.
Which key is this?
Solution:
Corolla/Camry and some Lexus 2020 to 2024 are 4A chip type, no way you will use that key because it’s 8A unless you use autel universal key.
For Toyota/Lexus 4A smart key, use universal type ikey instead. Low-frequency key here means universal ikey.
Or generate Xhorse XM38 with key tool max. It has been tested working fine on these models.

Lonsdor JLR Key 2020 Range Rover Sport Keyless Not Working Solution
Problem:
I got a customer has 2020 range rover sport.
New type key
I believe that that car has lost its keys before and some one did a key for it that start only with emergency and remote working normally( Lonsdor key).
The customer wants to do a key that works normally with keyless functions.
So the only method i got is to do RFA replacement and everything willl works normally?
Here some info got it from lonsdor k518 pro.
Solution:
If its PEPS key (passive entry, passive start) , you have to replace mcu in rfa module. Due to UWB function key clone wont work for keyless start.
Turn uwb off.
And add 2 Lonsdor keys.
Option 1 easy method. If you have autel, try generating a key in autel and hopefully everything works. If not….
Option 2. Replace SPC mcu in RFA. Write back proper calibration. Then add keys via obd.
RFA remplacement or MCU of RFA remplacement if you have soldering good skilks.
You need to replace the mcu and write data then program to car.

AutoTuner Adds Audi Porsche ASG1 ECU via OBD
We are thrilled to unveil a new technological breakthrough for our Autotuner Tool and AT One: the introduction of an exclusive protocol specifically designed for Audi e-tron / e-tron GT and Porsche Taycan (1st gen).
This protocol now enables full read/write access to Continental ASG1 ECUs directly via OBD. These control units, previously heavily restricted, manage engines that are significantly limited electronically, making them extremely receptive to performance gains.
Crucially, all performance enhancements remain safeguarded by the vehicle’s Battery Management System (BMS), which continuously monitors and ensures that power output never exceeds what the battery can safely deliver.
In short: we can finally unlock these powertrains and let them perform at the level their precision-engineered chassis deserves, while keeping everything fully protected by the BMS.
Key Features:
Type: Engine Control Unit (ECU).
Mode: OBD VR.
Readout: Calibration.
MCU: TC297.
Write time with patch: 10min 30sec.
Write time after patch: 1min.
Checksums correction.
Back to stock function (AT Tool only).
Compatibility List*:
Audi Models: e-tron - 2019 / e-tron GT - 2021.
Audi Engines: 50 Quattro / 55 Quattro / Quattro / RS / S.
Porsche Model: Taycan - 2020.
Porsche Engines: 4 PB+ (93 kWh) / 4S PB (79 kWh) / 4S PB+ (93 kWh) / Base PB (79 kWh) / Base PB+ (93 kWh) / GTS / Turbo / Turbo S.
*The list of vehicles may evolve over time.
