Just changed all the glow plugs in my MJ150 and i still get 'Check Glow plugs' on the readout. Any ideas anyone.

Have a look at the Glow Heater Relay unit. On a previous M-Jet Fiat I've had, the bolt that holds the ring terminal for the positive feed to the Heater Relay had rusted away completely. I took the box apart and permanently soldered a length of heavy enough wire to the "Feed In" on the inside of the box. You then seal up the box again and connect your new wires to the car's original cable and re-fit the box.

Hope it works out for ya.

There was also a recent post where the wiring was faulty between the relay and the glowplugs,

What now......

MJ150 - I still get 'Check glow plugs' error, but I have fitted 4 new plugs and a brand new relay:bang: It's embarassing when u start up in a dense cloud of blue smoke, so what can I check now?

Re: What now......

Only thing left is the wiring.
