2013 Audi A5 Alternating flashing red and yellow after decryption

0 votes
2013 Audi A5 Cabriolet, push to start. Evo-all with THAR-AUD1. Good connection at CAN hi and low and brake pedal, T-harness to ignition. Software 60.08. Evo-all S/N 001A07073896. Suggested options loaded. Decryption succesful. When I re-connection after decryption, I get alternating red and yellow flashing, with no responce from a 3X lock. I have decrypted with both key fobs, and no responce with or without a key in the ignition slot, doors closed, open, makes no difference, still no responce.

Any suggestions would be reatly appreciated.

Thank you,

Alternating red/yellow means dcryptor did not end successfuly,

After Dcryptor is 100%, wait until module reboots and Flashlink tell you to disconnect the module.

Hmmm, that's what I have tried. I will try again and maybe going back into bypass after encryption and save my options again?

Does it matter if the battery is in the remote? I have read on some of the Audi install manuals, that the battery needs to be removed for programming,

Thank you.
Ok, it took a few more tries, I think I got the Decryption to be succesfull. Now when I plug the module in, I get all three light flashing for about 10 seconds, but still no responce.

Any more sugestions?

Thank you!
Still no luck here. I did a reset and now I am back to the red and yellow, alternating flashing. I have done the dcryptor many times, sometimes I get an empty key data error, then the next try, it'll finsih succesful. I have a TB-VW, but don't think I need it, or do I? I have been programming with both key fobs with the batteries in them. Do I need to be using the valet key, the plastic wallet key?

Help Please!!

Thank You!
I would suggest calling tech support at this point when you have the vehicle and module on hand.

After some more tinkering here, I was still getting red and yellow flashing. I decided to update to firmware 75.xx, now FlashLink says I have exceeded my flash limit. I now get a responce from a 3X lock, some clicks and lights on the EVO-ALL and what seems like an attempt to start. I think I made some progress, but I can't adust any settings now.

I sent and email to support@ifar.ca with this photo of my EVO-ALL.

Will somebody be able to help me reset this?

I finally managed to get this to work, I used an EVO-ONE and every thing worked fine with OEM remote and RF kit.

Used 60.10.

Thank you!!
