Helping out on a another thread i found this in my list of faults that I never investigated as i wasn't having any problems:

Quote:

Glow plug relay failure - glow relay defective. This one should be investigated if your engine is hard to start when cold.

Time to check this out, seems to make sense as I have a starting up only issue ? .

Yes - I did ask the question earlier

9 times out of 10 , diesels struggling to start in the winter is either a battery not up to the job or glow plug issues.

May well be the answer...... There is nothing that can't be fixed with a hammer😜😜

I read & cleared & read faults with IIDTool and this keeps coming back:

It'll manage to start ok in the warmer weather

the cold has shown the fault up to be genuine

Not had it in previous years, even when -12 degrees, and it is the same even with a hot engine? .

Yes, it was two knackered fuel injectors.

I did a leak test to find them (which ones) and Dan at Duckworths happened to have some injectors in a sale of the century.

Leak test and replacing injectors covered elswhere by me on forum. Also my failed attempts to replace glowplugs still have three new glow plugs available for £15 each  .

Magic, thanks. That's pretty much what I was thinking then. Started with turning over a bit longer than it should in the summer, so I don't think it's glow plugs.

Will have to get some diagnosis done.....
