Trying to figure out what these parts are!

[FrankA6]

To make a long story short, my 04 A6 2.7T had a small engine fire caused by a failed power steering line, it damaged a bunch of vacuum lines and the engine wire harness.

I've tracked everything down but having a hard time figuring out this sensor, btw the 04 2.7T is a BEL motor but I figured I would ask on the b5 section since the C5 section is pretty dead these days.

Any help would be extremely appreciated!

This sensor came from the backside top of the motor, looks to be some type of temp sensor? it was charred so much that I can't pull any part number off of it and I can't seem to find it on any diagrams...



And this last piece is a plastic pipe that runs along the driver side valve cover, comes from behind the fender near the power steering bottle and runs down behind the backside of the motor, can't find any part number on it also.

I don't have a photo of it, but this gives you an idea where it runs.



thanks guys!

Kinda looks like the sensor could be the iat, but that would be under about the middle of the intake.

Id just run a new vac line instead of that plastic pipe.

I just replaced that plastic pipe on an allroad at work. You can just cut the pipe and slip some vacuum hose on it. No idea about the other thing; does look like a temp sensor.

Maybe get everything else sorted, fire it up and see what codes you throw?
