on a S1 205 GTI, under the front passenger's guard there is this "canister" like thing, with 2 small hoses connecting to the top of it.
Now, the thing is... one of the hoses has been dodgily spliced into another and as such does jack all! The hose comes up to a connector on a fat right-angled hose somewhere around the throttle body (if that's what it is called.).
I just need to know what this does, lol. Surely it has to be important if it is actually on the car!
Also, the vacuum advanced unit, is that the thing that is kind of like a circular disc on the side of the distributor? If so, that doesn't have any hoses coming off of it either.
Look forward to a quick response! Cheers
