	A3 8L Quattro AJQ ECU Swap to Wideband « on: May 04, 2023, 08:09:27 AM »

Hello, currently i have AJQ engine with ecu: 0261206269 06A906032AF 350034 0004 and want to convert it to Wideband.
Question is, can i apply ANY Wideband ECU ? or do i have to have Quattro one ? AWD ecu is hard to get in my region.

Thanks for reply.

For short.. yes. Any me7.5 forced induction ecu will work. Try sticking with mk4 ecu's from TT 8N, A3 8L etc., there are differences in some A4 B6 ecu's to my knowledge.

Ok then i am gonna use AUM or AUQ FWD from A3 or TT in my AWD AJQ.
Do i have to change soft coding for anything in A3 Quattro?

I have done this too a while ago on my AWD AJQ Leon

1.8T Alhambra wideband ECU
8N0906018H TT AWD base file

No issues works perfect
