Default They should be. I believe those are early 2001, pre-immobilizer...
should be a direct swap. I know for a fact that ATs are compatible without needing to be cloned.

I have a "T" and just want to make sure an "AT" will work

Default Yes! My TT had a factory "T" ECU but my chipped ECU was a "AT"...
And as JohnLZ7W said you do not need to worry about codes for an immobilizer. It's just plug and play between the two ECUs.
