What are these canisters?

fire_mike · 05-03-2011, 10:24 PM

What are those two black canisters for? Looks like something that has to do with vacuum. The reason I ask is because while I was trying to pull out my damn DRL bulb, the pliers slipped off and I hit the bottom nipple on one of them and broke it off!!!

Now I need to figure a way to fix it FAST!

Thats what it is!

Jb weld may work or taping it...

I've got some glue stuff I had in the garage on it right now (hoping it sets quickly), but I'd like to replace it with a new part asap. Anyone know where to get it online, or what it's called?

Lucky for you it only cost 29 bucks!

Goto dealer and order part #1 Here is the link of the part number

Thanks for the part number. It is only $29 everywhere I have checked, but everywhere also wants $14 to ship it.

If the glue I have holds well enough for now, I might just wait until I go down to Phoenix and buy one direct from a dealer there. I just don't want them to ask why I need it. . .

I think its for the brakes, so they have vacuum if the engine is off?

You'll also have no boost if you unplugged one.

Tell them the truth...its something that can happen to anyone...You can even tell him that your angel eyes light blew and you changed it out yourself and accidentally did this, but to be honest I dont think dealer's part department really cares...

A part description I found said the hold vacuum for the turbo system. Yay.

Hopefully it was a clean break... Epoxy should fix that if there's enough material left on the nipple and you let it cure overnight.

Those are vacuum reservoir pressure accumulators........one for each turbo's wastegate setup.
The wastegate actuators are driven via vacuum constantly supplied by the engine driven vacuum pump and then stored and regulated via those pressure accumulators.
To open and close the wastegates, the ECU sends a signal to the solenoid driven Electro-pneumatic pressure transducers, which then regulates the vacuum for wastegate operation. Since we have two of these pressure accumulators and solenoid tranducers which are both supplied vacuum in parallel, both operate in tandem.......so even though you only broke a nipple on one of those vacuum reservoirs, your wastegates would still operate although not at their ideal threshold.
There, I said it...............my head hurts.
