A4 flex fuel fifth injector location

[Ark88]

Has anyone located or swapped out the 5th fuel injector on their flex fuel vehicle. I would like to replace all 5 at once rather than just the 4, if anyone has any info please feel free to share.

Videos, write ups, or pics I'll take.

The 5th injector is in the intake manifold; it's a port injector, not a direct injector. I wouldn't associate too much between it and the other four. It's not even used that often, "cold start E85 injector".

If you're playing with the car at this level, erwin.audiusa.com, pay for a day, get all the PDFs for your VIN. Most everything you'll need to know is in there.
