Does anyone know where/what the 'Ventura' is on a 1.4 VW Golf? This is my girlfriends car and before the last service the car was very sluggish. The bloke at the VW garage told her he cleaned out the venturav (probably the only thing he did - its a long story) but anyway the car ran much better.

Its sluggish again and its not near its service time yet (and from now on it'll be DIY servicing) but can anyone direct me to the ventura. I've a feeling its known as something else as there are no references to 'Ventura'.

Thanks in Advance.
