Here’s the instruction on Audi A6 C6 4F (2004-2011) EZS kessy all keys lost with Autel MaxiIM IM608 by OBDII mode without removing BCM immo box. Maybe someone need instruction to get same work do to. Xhorse VVDI2 cannot this 100%, but have to remove immo box to read data and then prepare dealer key. It’s a major pain in the butt to remove the module. IM608 procedure is much easier and quick.
This is an Audi A6 C6 4F year 2005. The customer has lost all keys. I have to connect fuse box wire 15 and 30 fuse and get electric power on. Took about 10 minute work, very easy job, made Dealer key and program the key (aftermarket key) with IM608.
IM608 has no instruction for this car and situation. Have to use google to power up (bridge 15 & 30).
Internet was connected, all time when use device, don’t know how much is depends or not, but key programmed success and customer have a great day to get the car running again.
On instrument cluster is nothing immo data it not need to come on, it just give extra power to elv and ecu then you can read the data and make it run.
