Hi - just got a 1999 Charade 1.3 16V (HCE engine) & need a little help. There is a grey cannister-type component low down on the right hand side at the back of the engine compartment. A thin pipe comes out of this, runs up the side of the air filter housing and just ends. Can anyone tell me what the component is and whether the pipe should be connected to anything? The tickover seems high - 1500-1700 RPM at first, reducing to 900-950 when warmed up (about 8-10 mins). Any connection to the unconnected pipe? Any help appreciated...
