Problem:
After using Yanhua Mini ACDP Module 34 to read Dflash from Seat Leon MQB RH850 R7F701402 (which it did successfully) dashboard now completely dead, managed to also read pflash but think it’s corrupted as it gives checksum error or something, can it be repaired?
Solution:
ACDP has an option to restore data and repair the dead cluster. Do following:
Take the 7F701402 instrument cluster as an example
Menu path:
Go to VW MQB IMMO (ODO)->MQB48/49 ODO- Method 2 (R7F7014xx 5A/5C/5D)-> R7F701402-A (5A/5C)-> Special function-> Full backup data.
Do full backup data procedure, send the whole volkswagen data folder (zip) to ACDP team.
If need to change mileage on the cluster, provide the mileage you desire, ACDP will modify mileage for you manually.
If need to program keys, they will fix flash data, you can program key with the restored flash data.
To sum up, ACDP will repair data manually if data is lost or has issues.
If using other device, there is no option to repair data. You may need to buy donor dashboard and adapt with ODIS online Geko.
Buy other dash adapt with odis geko. Buy new (no used) instrument cluster and learn via odis online.
User working experience:
Donor cluster and write dflash from old one onto it which allows to program the key, car starts and runs ok and ODIS used to configure the rest of dashboard.
