Signs of a decryption issue (Bypass) on a VW Jetta 2015

0 votes
I have installed a EVO ALL on a Jetta 2015 TDI (Push Start - Automatic).  I have the EVO ALL, THAR-VW1 and TB-VW installed as per instructions (I decided to skip the trunk release wiring as I didn't find the feature useful for me case).   The EVO All is programmed with Diesel Option enabled and it went through the Decryptor without any issues.   But when I press the 3 lock sequence.   It doesn't start or crank.   I see the red light turns on,  and then the yellow light turn on... and it repeats this procedure twice (as per the options programmed).   The dash of the car doesnt come on (as expected) during the sequence.   I will check the brake lights when I have time but I was wondering if there is possibly something wrong with the bypass.  

Thanks

Assuming that both the (-)Start/Stop and Brake wiring is OK, then that means it should remote start if you sit in the vehicle with your key fob.

If the dash is not lighting up, verify the (-)Start/Stop connection. A15, Pink/Black, needs to be wired to the Brown wire on the T-harness.

Thanks for some reason I didn't see the Brown wire needing to be wired to the harness.   This helped with the dash coming up but now I am getting a "NO KEY" message.   I don't understand as I did the decrypt and everything went well.   Do you need to decrypt EVERY time you reprogram the device?

(If I keep the key in the car then the car starts up,  but as soon as I take it out of the car,  the "NO KEY" comes back)
