Recently, some AUDI models got in trouble of dead dashboard with a black screen and failed to communicate, all because of reading data. Share some professional ideas from Xhorse VVDI2 engineers.
Audi Q7 2015
Audi A6L 2013
Some other models that replaced J518 CPU
VVDI2 key programmer
Symptom after the car was dead:
The gateway cannot be activated!
Keys cannot programmed even online!
Change another new CPU or reflash J518 data
Engineer analysis of the cause:
The FLSH data in new models’ CPU differs a lot from the old’s/ earlier’s.
Attention please when read EEPROM data with AVDI, VVDI2, or AP!
If you use the default capacity: 128, then the car will be dead.
But select 256 as capacity, it would be OK.
Unluckily, AVDI, VVDI2 VAG, and AP cannot automatically recognize J518 capacity; so usually, DEAD.
So as for new models to add new keys, please manually select 256 as J518 cpu capacity with VVDI 2 commander key programmer.
AT YOUR OWN RISK to try.
