Glow plug timer mod, what glow plugs?

[Rickie3]

Hi Ricky3
If you have a Direct Injection 3 ltr GU then it will not have glow plugs
Glow plugs are only on indirect injection engines to get the 'recaro' pre combustion chamber hot enough to stop it quenching the heat of compression
So no glow plugs for Direct injection as nothing to pre heat
The 'Glow' light on Direct injection engines is illuminated whilst the engine ÉCU' goes through its pre start checks.
so no timer involved and no glow plugs
save your money for some thing else

ummmm now i'm confused, my 3L direct injection engine does have glow plugs, they are located under the intercooler I can see the bus bar running to them, and 4 rubber bungs at the top of them
