2005 Audi A3 AKL
First one programmed no problem with VVDI2 (OBD)
Next one (also 2005) got pin code and CS with Supervag as VVDI2 wouldn’t read codes and entered codes manually but VVDI2 wouldn’t program transponder.
What to do?
Experience for sharing: maybe dash fujitsu? Try use carprog for read CS and prepare key. I tried on table and now key prepare by carprog is correct – dash see new key as DEALER.
I have this dash for test and read immo data on bench, only use gateway, no need wakeup.
VVDI2 read pin and 6 byte CS from ECU, but can’t read immo data from dash.
Thanks to @castin (dk forum) for experience sharing. It’s very nice.
