Hi, hopin someone with prior knowledge who can help? my motorhome has developed a series of faults, its an 06 plate 2.8 jtd and on recent journey home engine m/ment light came on, booklet reads injection system failure but also the speedos gone off, diagnostics say a multitude of faults po148 , p1612, po380, po382. its all double dutch to me and my mate is stumped, does anyone have any ideas? cheers

P1612 Fuel filter heater relay

not sure on the others

I'd clear the errors first and see which ones reappear in the short term.

Just for reference if they are of any help here are the fault codes -
P148 - Fuel delivery error - fuel pump/injection pump
P1612 - Fuel filter heater - Fuse, wiring poor connection, Fuel filter heater relay, Fuel filter heater, ECM
P0380 - Glow plugs - Circuit A malfunction, Wiring, Glow plug relay, fuse, glow plugs, ECM
P0382 - Glow plugs - Circuit B malfunction, Wiring, Glow plug relay, fuse, glow plugs, ECM
Maybe of some help!
Cheers

Hi
Just a thought, all the fault codes seem to relate to big power users is the battery O.K?
Cost nothing to have it checked.
Also I would check out the earths on the chassis and the engine again cost nothing and worth a go.
