okok, you KNOW I searched...

I know you can swap ECU's in B5's and can modify the Tip/Manual with a VAG-COM, but can you swap ECU's in a B5.5? I had heard rumors that it was not so simple; is it true?

thx much!!!

If the part numbers match, you can swap. However, you will need to get the immobilizer reprogrammed at the dealer to match your keys.

Does every number and letter have to match? Mine ends in DA and the other is CM. All of the other numbers match. Mine is 2003 1.8t 5 speed and his is a 2002 1.8t 5speed. Can anyone with vagcom redo the keys or must it be done at the dealer. Any help is greatly appreciated

You cannot program a B5.5 Immobilizer anymore with a VAG-COM. See the Ross-Tech web page for why. You MUST get that done at an actual dealer.
