DIY: TSI Tiguan Pipe Install / Noisemaker Delete

*Do at your own risk*

VW OEM PARTS:
1K0-145-770-N – Tiguan Pipe

1K0-971-866-A -- Firewall plug
1K0-971-865-A – Firewall Clip

OR a 2” Qwik Cap from Home Depot


TOOLS:
Torx T-30
Torx T-25
Flat blade screwdriver
Channel Locks
Ratchet
Ratchet Extension
7mm socket
13mm socket
10mm socket



1. Remove hose clamp with channel locks by the throttle body (slide to the right) & Remove T-30 screw

2. Unclip the 2 rubber hoses

3. Undo the T-30 screw

4. Use the flat blade screwdriver to pull up the clip....then pull out of the noisemaker inlet

5. Remove the plumbing from the car

6. Loosen up the upper clamp with the 7mm socket & unclip the boost sensor harness (push back on the tab & then slide down)

7. Undo the T-30 screw

8. Remove the (8) T-25 screws holding the belly pan on

9. Push on the tabs to release it from the car & set aside

10. Loosen up the lower clamp with the 7mm socket

11. Undo the lower T-30 screw

12. From under the car, pull down on the stock pipe to remove it from the throttle body hose & then wiggle it free out of the car.

13. What you removed

14. Comparison picture



15. Swap the boost sensor over to the Tiguan pipe with a T-25 Torx

16. Reinstall in the car…sliding the pipe up from underneath the car. Slide it into the throttle body hose FIRST. Then connect the lower intercooler hose. Makre sure everything is lined up, then tighten the 2 screws on the pipe to the engine block. Then tighten down the stock upper & lower clamps. Reconnect the boost sensor harness.






17. Remove the alternator bracket (if you wish)…since it’s not needed anymore. It’s 2x 13mm bolts.

18. After removal

19. These 2 hoses can be zip tied together, OR I used a OEM clip from a Passat/Tiguan to hold them together (since they don’t have the noisemaker from the factory).



20. Now you have a opening for the inlet of the noisemaker.

21. You can cap it off with a $4 2” cap from Home Depot





22. OR you can use the Jetta firewall insert for a cleaner OEM look

23. Remove the weather stripping (just peels off) & foam inserts on the ends

24. Remove the firewall panel…..lift up on the wiper cowl to see the 10mm bolt on the passenger side & the 10mm nut on the driver’s side. Make sure the wire harness on the back side of the panel is removed from the clips on the back, before you remove it.



25. Here’s the noisemaker. It’s held down by (2) T-30 screws. Remove them & then you can wiggle the noisemaker out from under the cowl





26. Now you’re left with a hole in the firewall plug.

27. Remove the upper clip (2 prongs on each side). Push back on the “plug” & wiggle the harness out of it to fully remove it

28. A comparison of the 2 firewall plugs

29. The new firewall plug & top clip



30. Slide the harness into the new plug & snap it into the firewall. Then snap the top clip onto it.

31. Put the firewall panel back in place. Make sure the wire harness snaps back into the clips on the back of the cowl piece as well. Tighten down the 10mm bolt & the 10mm nut. Install the weather stripping & end foam pieces.

32. Finished product





33. Compared to stock

Awesome write-up, man! This'll save a lot of us some cursing and skinned knuckles. :thumbsup:

STICKY!!!

Yeah I meant to do the write up when I had my MKV, but never did.....so when I did it on my MKVI....I finally finished it

Whats the point of this??

Uhhh...didn't you see the pictures?

1. Better throttle response (due to less boost plumbing)
2. Cleans up the engine bay by removing the unnecessary piping
3. You can hear the engine/turbo instead of the fake noise that the noisemaker creates

Good write-up, well done. I gotta get around to mine when I have the time.

Now sell me the tiguan pipe lol ahaha...nice write up man

what is the part number for the little clip you used to hold the two hoses together? Good write up!

lol still pointless, if i wanted all the swoosh sounds I would have bought a srt-4.

Wow your retarded. What's pointless is that pipe making useless noise inside the cabin of your car. It has nothing to do with a blow off valve sound

Do a search for "noise pipe" on these boards. You'll learn that VW made a "pointless" noisemaker for the GTI that uses boost piping to make "fake engine noise". This mod is to get rid of that noise and improve throttle response.

I don't have the part number, sorry

I "borrowed" it from a Passat, and there aren't any markings/part numbers or anything on it

Just seems like a universal VW clip :iono:

OR just use a zip tie like I did on my MKV before I found the clip

LoL so i'm going to spend money to make the turbo sound go away . . .
great write up by the way

Do you even own a GTI? :iono:

You're missing the point...the noisemaker uses "boost" & extra plumbing to create a muffled sound inside the cabin....which doesn't allow you to hear the turbo at all

Deleting it (the whole point of this write up), allows you to actually hear the engine & the turbo "spool" (instead of a muffled/fake noise that the noisemaker creates)

Are you just turning a blind eye to multiple people also saying "IMPROVED THROTTLE RESPONSE"????

Have you even researched what the noise pipe does and how it goes about doing what it does??? Unnecessarily diverting boost to provide some sound when it could be used by the motor right away if there wasn't an extra unnecessary pipe to fill with boost.
