Programming sequence breaks at step 5

Question

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?

Hello,

"I couldn't find wires next to steering column. Could this be a problem?"

- Yes, this is the problem.

Best regards.

Answer 2

Hi, I looked at the pictures at https://www.wirecolor.com/en/vehicles/audi_a4_allroad_-_key-port_(2008-2014)_tdi_key-port_(2008-2014)/ - they are all different from my car. Maybe the fact that this is A4 allroad and not regular A4...

So I connected to a different pair of cables inside driver kick panel, see photo (red connector), orange pin 8 on the left and pin 9 on the back row.

Still, same problem...

Blue led illuminates originally, does it mean that it sees canbus? (blue led is supposed to mean canbus indicator?)

Any additional advice?

Thanks!

If the blue led does not flash this indicates an issue with the grey and grey/black wires coming from the evo-all.

If you turn the ignition to the on position and metter grey and grey/black wires 1 at a time, what do you get for voltage readins on each wire?
