    You get a better burn with the direct so slightly better power and MPG but a hefty bill when the directs fuel pump goes, and yes it will go.

    Is it a renowned problem with the pump?

    Yep in a big way. It was even featured on BBC watchdog. The normal 2.2 does not suffer from this problem, only the direct.

    Wonder if that's what's wrong with mine (see my post in Troubleshooting ). Will find out later today (hopefully) when the garage report back.
