How to Solve Yanhua ACDP2 Failed to Reset BMW FEM BDC Mileage?
Customer problem:
I tried to use Yanhua Mini ACDP2 to change km on a 2015 MW X5 with BDC immobilizer system. Initial programming succeeded but failed to reset, and appeared the error message “Reset FEM/BDC mileage failed”.
EOBDTOOL.co.uk engineer gives the solution below:
1.The possible cause is that you got the wrong connection between ACDP2 and FEM/BDC interface board, and the mileage, key frequency and UNKN info are lost.
Please check the correct interface connection as follows:
2.Then perform Step 6: Remove EEPROM Data and Step 7: Recover Coding Data to restore coding. Make sure you back up the original data before operation.
Restore the original data.
3.If restore coding is completed, but still fails to reset mileage.
Please check the BTLD software version.
If the version is 082, you cannot reset mileage by removing the BDC module. Please purchase Yanhua ACDP Module 31, and select “BDC OBD (F Chassis)” option to reset mileage.
Customer feedback:
Thanks so much! The device info can be identified now, and I reset km ok.

Launch X431 Program Keys to VW MQB RH850/V850 Cluster, Yes or Not?
Question:
Is it possible to add new keys or do all keys lost to VW MQB RH850/V850 Cluster by Launch X431 tool?
Here is the answer from EOBDTOOL.co.uk engineer:
Yes.
Currently, Launch X431 X-Prog3 Key Programmer not only can work with Launch RH850 Adapter to read and write Renesas encrypted RH850 R7F701xxx 48-PIN, 80-PIN, 100-PIN, 144-PIN, 176-PIN MCUs (click here to review), it also can work with X431 IMMO Plus, X431 IMMO Elite, IMMO Pro, IMMO PAD, etc to program key to some VAG MQB RH850/V850 R7F7014xx 5A clusters as follows.
R7F701401
R7F701402
R7F701404
R7F701406
R7F701407
Note:
1.Add key and all keys lost are supported. All keys lost require sync data.
2.Mileage correction is not supported.
The corresponding wiring diagram can be checked on the Launch X431 Tablet.
Some clusters require removing some components (resistors) or cutting wire.
X431 X-PROG3 comes with an integrated MQB2 calculator.
Under the 'All Keys Lost' function, there is an option to 'Obtain Sync Data'.
With this built-in MQB2 calculator, you can retrieve the sync data for free. You will need to collect the Component Security (CS) codes from each module: the instrument cluster, ECU, gearbox (if automatic), and Kessy (if keyless).
Instrument panel CS code: 16 bytes
ECU CS code: 16 bytes
TCU CS code: 16 bytes
ELV CS code: 16 bytes (if present)
Once you have gathered these, you will be able to obtain the sync data for free.
In addition, CG100X supports mileage correction for MQB RH850/V850 5A and 5C clusters.
Yanhua ACDP2 with ACDP Module 34 supports RH850 series 5A cluster IMMO and mileage correction and 5C cluster mileage correction.
Xhorse Multi- Prog/VVDI Key Tool Plus Pad supports MQB RH850 5A clusters IMMO programming.

How to Solve Yanhua ACDP2 Exceed Server Calculation Limit?
One customer used Yanhua ACDP 2 with Module 19 to clone DQ500 0BH Continental and he got the prompt “The number of server calculations has exceeded the limit”. Did the limited 5 connections to server over 24h period?
EOBDTool.co.uk engineer replied:
Yanhua Module 19 doesn’t have a limit, but because the Continental is connected to the server, and it has a limit of times. You can wait and use it tomorrow.
In addition, Yanhua Module 16, Module 25, Module 26, Module 27 and Module 30 also have server calculation limit.
If you are urgent, send the Mini ACDP serial number to ACDP engineer to add 1–2 calculations.
