CG FC200 Audi DQ381 Error E111 Security Authentication Failed

 Problem: Trying to read an Audi Bosch DQ381 gearbox with CG FC200 ecu programmer on bench but failed to connect with this TCU.

It says error "E111 Security Authentication Failed", Any solution?


CG FC200 Audi DQ381 Error E111 Security Authentication Failed

Solution:

The boot version is bh1g0401.
This is generation 2 bootloader 401.
You can not read it with fc200.
Software too new and fc200 can’t break security, yet.

Flex or Autotuner can do it.

 Here is basic post for people asking basic questions, apparently now on high demand since we have gathered again new members in our ECU group . So you got bosch ecu in hand from car and how to figure out how to identify it and what pinout to use? On this case we can randomly take one bosch ecu that we will identify. So all bosch ecus start with serial numbers 028… 026. We just head to bosches page next https://www.bosch-repair-service.com/ Here you search by oe or bosch number, i have random bosch ecu here and it’s 0 281 014 544 and bosch page ends up with a result. We can see its edc16cp35. Now there are two ways. Either to search in foxflash bmw / edc16cp35 for pinout. Or we head to ecu pinout page and figure out pinout from there. One of the best online pinout catalogs can be found at ecu desing, So save webpage https://ecu.design/ecu-pinout/ Copy address and head out there. Type in edc16cp35, bmw uses two processors in this one mpc 562 and mpc564. Pinouts jus...
