I have 2013 Audi A4. Following guide #77151 - EVO-ALL_IG_THR_BI_AUD1-A4-A5-Q5-S4-S5_2015_PTS__A_77151.pdf
On page 6, step 5, when I press and release programming button, blue led just turns off, and does not flash rapidly. I tried it a lot of times. After that, there is no way to continue.
1) I connected CANBUS hi/lo wires to the OBD port, I couldn't find wires next to steering column. Could this be a problem?
2) There is a 4-pin socket (blue) and connector (black) on the harness, next to 4-pin black connector that goes into EVO-ALL unit. I tried it both connected and disconnected, same results.
Any ideas?
