Hi,
I'm Izzy.  I've been working on VW's since 2003 with my first one being a B3 Passat.  In 2005 I move to a VR6 Corrado which I still own till this day.  I was able to get the VR6 to 453hp and 420tq but family growing made me think my options if I wanted to continue down this path.  In 2012 I sold the VR6-T with a GT3582R turbo and swapped in a 01 Audi ATC 1.8T motor being ran by B5 AEB ECU.  It's been running great with an APR tune but now I would like to open my horizons and move into DBW.  I'm building an AWM (5 speed manual) harness currently while in quarantine and decided to look into tuning since now I have to start dealing with the IMMO and EVAP systems delete.  I know the AWM ECU # 4B0 906 018 DA, and I also have 4B0 906 018 BQ which has a lot of things it controls which I just been realizing.  I will need a lot of help since I've never done anything like this.  I've been reading this forum and it's a lot of information to take but in these times, time is something we have.  If anyone has a suggestion of how to go about removing the IMMO, ABS and LDP codes I'm a humble apprentice.  Thank you to everyone that has invested so much time in this forum to make it a one stop read.
