So I just made a pretty big mistake, broke this coolant pipe stem while disconnecting the line from it - it’s one of the two coolant lines that hook up to the intake manifold. I need some ideas on how to repair this without replacing the entire coolant pipe. My best idea so far is to tap it and install a new stem, just not sure on the logistics of that as I’ve never done it with a coolant system. Please give me any ideas. Any help is seriously appreciated.

Ah well the part is only $80 and everything is accessible so I’m just going to replace it.
good stuff.
That was lucky…glad you got it sorted…
Me thinks your engine needs a bath ;D
seriously…I read the title…then saw the pic and thought he was going to say ’ I accidentally drove into a sandstorm and accidentally left my hood open’
lol
for emergency repair you can tap out the stem and use a selftapping screw then use jb weld.
You might be able to just bypass the intake manifold and save yourself 80$ and sometime.
If you can get better pictures I can tell you if you can just bypass the line going threw the intake. If its what Im thinking this might turn from a need help/ Urgent to a DYI mod thread.
Ill keep a close EYE on this thread today if you need support
tech assistant: the broken stem and the unplugged stem in the picture both had small coolant hoses leading to the intake manifold right under the throttle body.
I had a thought earlier today that these two lines might be functioning as a throttle body heater. After speaking with Count a few hours ago, I believe this is correct. I think the one that I broke is the input and the one that is still there is the output. The part number for the entire coolant pipe is 06C-121-085-H. Fortunately I won’t be purchasing that part and my weekend got a whole lot better because of it. I’m going to go ahead and block off both of those stems on the main coolant pipe.
I’ll be editing the original post with DIY info on installing the intake manifold spacers, removing the SAI pipe, and blocking off the throttle body heating lines.
Count: thanks for making my weekend good again.
looks like it really snapped off in a odd spot. Chances were good that it became brittle over time with heat cycles. Looks like a great opportunity to do the coolant bypass.
Im glad what seemed to be a concern has turned into a great performance project. 
Great man looking foward to this. I did something simmilar so its great to see more of this.
Please excuse my ignorance I’m not good with the technical peices and I might of missed this peice of information but why is the secondary air injection pipe being removed? Can someone please explain the advantage to this?
eeehhh… it seems like I’m really good at breaking stuff. I got everything back together and operating properly, but broke the cylinder head vent hose in the process. It was really brittle and snapped with very little pressure.
Can anyone ID this part number for me? Highlighted in red. It connects from the left valve cover to the breather valve.
I have a etka let me look for it. Ill get you the part number later today when I get off work, if someone else doesn’t beat me to it.
komseh - I think I have a lead on that part. Check your email, there’s a VIN split.
check out my lowes handy/crappy work for a temp. fix:
It works… I think I might even look at getting a 1" ID vacuum hose to to replace the original tube since it’s gonna be a hell of a lot cheaper, and in my opinion way better. The original tube is just a pain in the ass to work with in every way, not to mention the material degrades to peanut brittle. I really hate Audi’s clips and fasteners.
I’ll be creating a new thread for the stuff I did. It should provide some useful tips to those that will do this stuff in the future, hopefully saving them time and headaches.
