1999 Audi A6 95k miles Throttle Body Issues?

[Mr C]

I have a 1999 Audi A6. I was experiencing some problems with it where it would not let me go past 20mph. Recently I had to jump my car several times and I think it was the battery that caused it so I replaced it. But now the car dies suddenly after i start it up. I get a P1545 check engine light code which I know that code points to Throttle Position Controller Malfunction. So I bought a used Throttle Body from the junk yard and that didn't help. I dont know if that was bad also.

I have also tried to do a throttle body adaptation manually but everytime i try to erase the Check engine light code (with my obd II reader) it is still there. I even tried to remove the battery for 30 minutes and it wouldn't remove.

I then turned my key to the on position for 20 minutes and turned the key off and back on....Still nothing...

I am stuck on this...What do you guys suggest?

Also can someone give me instructions on how to do a throttle body adaptation with the VAG-COM?

Thanks!
