I have a 2001 115 pd golf. Recently had a new change over valve fitted under warranty.
fuel consumption has gone up by 15% on like for like journeys
dealer says the car is set up properly now.
would this valve have starved fuel so much when not operating properly prior to new fit?

Please excuse my ignorance, but what is this change over valve?

Where is it fitted, what is its function?
