Massey Ferguson 7495 error code E9171

[norse]

My tractor is showing error E 9171, 'Engine pre heater', I have changed the control relay located on the inlet manifold and removed the heater element and checked it to find it ok but I am still getting the error code and dash lights flashing,still goes fine and isn't in limp or derated but I am struggling to find the problem,has anyone else had this ?

It is a T3 common rail tractor

Check the plugs on the ecu they can either get corroded or fill with engine oil.

I checked all the plugs on the ecu and all were fine and still getting the error code so I checked the plug on the relay again and the code has gone so must have been a bad connection there
