Make sure your writing tool does checksum on flash. This function also allow you to edit VIN. Require full read EEPROM and FLASH to work. VAG DSG TEMIC TCU EEPROM + FLASH IMMO OFF:ĭSG TEMIC D元81 D元82 DQ200 DQ250 (GEN2 AND MQB), this is a total immo off. The generated file will be ready to write. This function now calculate and correct the file checksum. This function will not work with virtual read. This is a very exclusive feature, again we garanteed* no dtc and no immobilizer message failure, this is a total immo off in flash + checksum correction. You can consult the tested files list. MED17/EDC17 FLASH checksum correction is not made by the software, make sure your writing tool does it.

We runned the algo and tested it against 5600+ files. The function will automatically detect your flash will apply the right patch over it. It will work on ALL MEDC17 ecu from VAG from years 200X to 2021. This is a TOTAL immo off for MED17/EDC17 in FLASH only, this is a new way to patch, it does not require eeprom modification anymore and it does provide an immo off with NO DTC AND NO IMMOBILIZER MESSAGE FAILURE, THIS IS GARANTEED*. This service will disable and correct checksum on eeprom for following ecu: MED17/EDC17 WFS5, MED9, EDC16, ME7.X, EDC15. I assume in this case that the security data pin/code is still on the eeprom for BSI coding.SOLUTION WORLD-WIDE AWAITED IMMOBILIZER REMOVAL:ĭSG TEMIC FUNCTION ALLOW YOU TO EDIT VIN. So what are the impacts on the BSI? Does the three connector ECU use the flash to check the security code/pin, or the eeprom?ĭoes this mean if you write a different file to the flash on any PSA three connector ECU then the immobiliser won't work? Ie, you'd need to always edit the original file if remapping? Three connector sounds like it has coding for immo/security on the eeprom in an encoded form, which can be decoded to then be able to be written to the flash (if you need to) Single connector had coding for immo/security data on the eeprom. I'm a little confused about how the PIN is stored and used from single connector to three connector ECU's.

So the eeprom contains data that is checked against the flash, so the data in the eeprom is like a checksum for the flash data too?

If you just wont to adapt keys for PSA group PIN can be calculated from eeprom - PIN can be programed to the ECU. Tihiuvek wrote:If it is EDC15C2 Ecu with 3 connectors immo can be removed only in flash (AMD29F400BT) all other EDC15 can be done in eeprom (95160, 95P08.).
