This cable allows you to connect your CMDFlash to Temic DSG DQ250 controllers. This can be used to read out the original file when virtual read fails, as reading over OBD in tricore versions of DQ250 is not possible (type Exx and Fxx).
It can also be used to read/write all versions of DQ250 on the bench (type Cxx, Exx and Fxx).
The cable has both K-line and CAN wired (with integral termination resistor) and is fitted with a DB9 plug for a direct connection to the CMDFlash interface.
After failed programming due to bad checksum calculation or TPROT protection activation the VAG MEDC17 control unit can “lock”, resulting in the ecu becoming stuck in programming mode and no possibility to complete a write over OBD.
We offer a recovery file service to restore the ecu back to a fully working state.
We can also if required disable on TPROT active ecus the RSA signature check routines allowing flashing of modified files over OBD!
