Title: Possibly to connect vagcom for recode on bench? Post by: overclockedpc on August 28, 2015, 03:23:44 PM I'm wondering if it's possible to recode an ecu on the bench with VCDS/Vagcom? I couldn't get vcds to connect with wiring connected the same way as we would connect for bench flashing.

Title: Re: Possibly to connect vagcom for recode on bench? Post by: overclockedpc on August 28, 2015, 07:50:14 PM Yes sir, power to pin 3,21,62,121, ground to pins 1 and 2 and k line to pin 43.
I successfully flashed the ECU with the same setup. Title: Re: Possibly to connect vagcom for recode on bench? Post by: overclockedpc on August 28, 2015, 07:50:42 PM I should add that I tried with and without power to 121
