Hi
Yesterday I tried to connect to the DSG DQ500, but without success.
After entering the command to read the MCU, a click was heard in the mechatronics area for 10s and the following error was displayed:
Error while Processing -Ref: 848-
I was disappointed and so was the customer.
I also wonder why I can't use hextag to read offline?

Hi
This error is similar to no communication with TCU. If you still have TCU please contact support to check.
Thank you

Right now it is supported DQ500 MQB, other versions may have some differences in the software, It is advised to contact the support team with TCU to check if it can be read.

It would be time for the developers to start dealing with this problem.

Today, same gearbox, same error and same result. I could not read any data from TCU.
I read DQ200, 250, 381 without problems.
It's sad that no one from the development department was concerned about it.

DQ500 MQB is supported as explained. DQ500 other versions are not supported and as for now, it is under development.

After a long research, I found out that there are two types of DQ500MQB.
DQ500 Bosch - Hexprog has RW support
DQ500 Continental - Hexprog not supported - gearboxes for vehicles with BITDI 240HP engine
