Done all I can think of that's obvious, can any one see the connection in these fault codes?
5 Faults Found:
17957 - Boost Pressure Regulation Valve (N75): Open or Short to Ground
P1549 - 35-10 - - - Intermittent
17849 - EGR Valve (N18): Open Circuit or Short to Ground
P1441 - 35-10 - - - Intermittent
19561 - Valve for Intake Manifold Flap (N239): Open or Short to Ground
P3105 - 35-10 - - - Intermittent
18027 - Glow Plug Relay (J52): Open or Short to Ground
P1619 - 35-10 - - - Intermittent
17660 - Cold Start Injector (N108) Open or Short to Ground
P1252 - 35-10 - - - Intermittent
must be a common denominator?

If you clear the faults but that lot keeps coming back I'd be checking earth points, battery cables, earth strap to gearbox etc.

If it was only a couple it'd be different but that's quite a lot
