Audi A6 J518 Dash is Dead with Black Screen (Solved)


Audi A6 J518 Dash is Dead with Black Screen (Solved)


Recently many Audi (A6,Q7) cars got in trouble of dead dashboard with a black screen and failed to communicate. Here’s the engineer solution to the problem.



Audi Q7 2015

Audi A6L 2013

Some other models that replaced J518 CPU


Device used:


VVDI VAG diagnostic interface

Symptom after the car was dead:

The gateway cannot be activated!

Keys cannot programmed even online!



Change another new CPU or reflash J518 data


Possible Cause:

The FLASH data in new models’ CPU is different from the old/ earlier.


Please pay attention when read EEPROM data with AVDI, VVDI/VVDI 2!

If you use the default capacity: 128, then the car will be dead.

But select 256 as capacity, it would be OK.

Unluckily, AVDI or VVDIcannot automatically recognize J518 capacity; so usually, DEAD.



If you want to add new keys to new Audi, please manually select 256 as J518 cpu capacity withVVDI commander key programmer.


Good Luck!
