What is this Charcoal Filter?

[Applemobile]

Stupid question comming.....

What is this thing in the pic? it seems to me to be some kind of charcoal filter maybe? Can i remove it? do i need it? if i do remove it, can i just block off the pipes and bridge out the wiring? taaa (sorry i stold teh engine bay pic off someone on this forum)

Carbon canister - ticks when the engines running (more noticeable when cold) - not sure about removing it but helps with emissions on cold starts, and don't think there's any perfomance to be gained by removing it, and may cause excess emissions come MOT time if removed (possibly - others will likely know more)

cheers mate. Im not removing it for any performance reasons. Im doing a light ''tuck'' on my engine bay. So everything i can remove will go. I doubt it would make too much difference to my emmisions. Could it? lol

 

[Cupra Kev]

I doubt VAG would have put it there if it didn't do something for emissions - like I say not sure how much effect it'll have, but you may run into problems - if you have a exhaust gas tester could always check if it does anything to emissions

Mk2 Ibiza but probably relevant - http://www.seatcupra.net/forums/showthread.php?t=211701

i wouldnt agree with that tbh. Look at hondas running charcoal canisters...unless you live in calafornia, they are pointless. Yeah it probably will reduce my emmisions but i doubt it will be to a point it could fail mot. All the Mk1 golfs with the 1.8t conversions i have seen never seem to be running them.

awsome link mate. Cheers! it will be going! i not lik ethe sound of that pipe bieng a fuel tank breather tho lol. May have to put a lil filter on that and make sure its out of teh way of all sources of ignition!!

Its now gone, history, nil, zilcho...thanks for the help :d

I'm been thinking about doing the same as well. Only reason being that it would tidy the engine bay up as the hoses run quite a fair way. The hose is split and goes to the TIP and to the top of the intake manifold on my LCR.
Did you just block these two holes up?
Where did you run the hose from the fuel tank?
You got any pics?

 

[Applemobile]

i got some pics of how the bay stands as of today....and yes....its getting painted soon.

the pipe to the tank seems to have a 1 way valve....so it is only open when the inlet manifold is sucking on it. I just ran it down behind the expantion tank and into a hole on the wing. I blocked off teh vacuum pipe. and just cable tied the wiring out the way.

 

[rikwheeler]

Ok cool. Will give it a go soon.
Has anyone done this on an LCR?

 

[rikwheeler]

Can understand why the hose would go to the intake manifold but I'm curious to know why the hose is split to go to the TIP as well. Anyone know?

 

[Applemobile]

teh fumes are released back into the inlet...thats why.

 

[rikwheeler]

But if the fumes eventually go into the inlet then why not just route the fumes to the TIP OR to the inlet. Why both? Sorry if I'm just being stupid here

 

[Applemobile]

tbh mine just routed into a mass of vacuuum piping...didnt really pay attention to where it went. Just presumed it was to the inlet. If ot does go to the 'tip' then i presume that is to heat up the fumes before they are burnt via the turbo??

 

[rikwheeler]

That's how the LCR hoses are routed (I've modified the diagram to include my FMIC instead of the two SMIC):

Would love to know why the hose is split to the TIP and to the intake.
Obviously I'm going to remove them but it bugs me because I don't understand why it was done like this

Would like to block the two holes in the intake and the TIP but I'm not sure what with?

 

[Applemobile]

looks like its just done to heat up some of the fumes as i said. Run it through the turbo first.

 

[rikwheeler]

Finally got round to removing it. The sensor is now not connected to anything and the emissions light has come on the dashboard. Did you have this problem?
