Hi all!

Think this is the right place to post this, so here goes.

The engine service light came on today, so read the code and got the following back ...

P0456 - Evaporative emission system leak detected (very small leak)

The car has recently had a Procharger installed.

When I started it up today the code was there instantly.

To do with the vacuum lines I been messing around with installing the boost sensor perhaps?
