Yanhua ACDP2 Correct Mileage on 2022+ VW DQ38x Gen2 Guide

In this post, you'll learn how to perform mileage and runtime correction on 2022+ VW DQ38x Gen2 (0DE/0GC) and DQ500 (0DL) transmissions using Yanhua ACDP1/ACDP2 on bench. These units feature the BH1G0401 bootloader and a 7-pin TCU connector.

 

Three hardware options are available:

• Option 1: Mini ACDP1 + ACDP1 Module 45
• Option 2: Mini ACDP2+ ACDP2 Module 45
• Option 3: Mini ACDP1/ACDP2 + A60B License+ Module 19, 25, or 30

 Tip for existing users: If you already own ACDP Module 19/25/30 or ACDP2 Module 19/25/30, you only need to purchase Module 45 A60B license. No additional hardware required!

 

Step-by-Step Instructions

The following example uses Yanhua ACDP with Module 45.

Step 1: Verify Your TCU

Open the hood and locate the gearbox TCU. You are looking for a 7-pin connector

✅ 7 pins → Proceed with this guide

❌ 4 or 6 pins → Stop – this method is not compatible

Step 2: Connect Hardware

Disconnect the original gearbox connector

Attach Mini ACDP and Module 45 SH25xx-0DE board to the gearbox

Set the jumper cap to the "CAN-R" position

Power on ACDP device

Step 3: Read Current Data

Open ACDP App

Check the top-right corner – ensure your device shows as connected

Navigate to:

VW/AUDI → Gearbox mileage correction → VW → DQ38x_Gen2 (0DE/0GC)

Tap "Identify info"

The app will display:

• Current mileage (e.g., 17,150 km)
• Current runtime (e.g., 453 hours)

Take a screenshot and save it for your records

Step 4: Change Mileage

Tap "Mileage correction (auto mode)"

Wait for the tool to read system and chip data

⚠️ CRITICAL: Save the EEPROM data – this is your backup

Enter your desired mileage

Example: 16,300 km (was 17,150 km)

Tap write to program the chip

Wait for the completion confirmation

Step 5: Change Runtime

Tap "Time correction (auto mode)"

Verify the mileage field shows your new value

Save the EEPROM data again

Enter your desired runtime

Example: 450 hours (was 453 hours)

Tap write to program the chip

Wait for the success confirmation message

Yanhua ACDP2 Program BMW BDC2 All Key Lost FAQ

Yanhua Mini ACDP/ACDP2 with Module 38 can program BMW BDC2 all keys lost on bench. The

BMW BDC2 Keys Learning Bench Platform is required to work with. Here have collected some frequently asked questions for reference.

Q1: Yanhua ACDP2 support BMW BDC2 All Keys Lost now? Is it true?

A: Yes! It needs Module 38 + BDC2 Keys Learning Bench Platform.

Yanhua Module 3 + B48 Interface Board are also required for DME B48 EEPROM data backup.

 

Q2: Can the BDC2 Bench Platform work with other devices except the ACDP host?

A: Yes, it is compatible with other tools that support BDC2 all keys lost.

 

Q3: How to read a locked ECU?

A: The DME module is not locked, so no special steps are needed.

 

Q4: Is reading ISN required?

A: No, but you must back up the engine EEPROM data (Step 1) using Yanhua Module 3 and B48 Interface Board. This data is used for Step 6 (Write DME ISN) and Step 7 (Reset EGS EWS).

Q5: Can't read with another device? Is it necessary to have all the adapters for each version of the BMW engine to make the first step (backup coding data)?  

A: Use Yanhua Module 3 and B48 interface board to read the EEPROM data of DME B48 SPC5777. You also can use other available devices to read the data.

 

Q6: Do I need extra modules to do Step 7 (Reset EGS EWS)?

A: Only require the Yanhua BMW BDC2 Keys Learning Bench Platform. Then reinstall BDC2 in the car and reflash via OBD after programming.

 

Q7: Does it also require parts from a donor vehicle the front left and right antennas? What can the antenna do? Is it necessary?

A: No.

The LF Smart Key Antenna & Remote Control Receiver are used for key functionality (intelligence & remote control) testing.

If you don’t have them, just reinstall BDC2 in the vehicle for testing.
