Cold starting problem
2007 tdv6 Disco - needs atleast 3 heats in the morning, to start first time, otherwise turns over for 4/5 seconds before starting, once started will start first yime all day long until it gets cold again? My thoughts are glow plugs but everywhere i read say they all snap when changing?

Is the battery in good condition?
Yes they are notorious for glow plugs seizing in the heads so backup plan required.
Many folk will fit a timer to run the fbh as an engine pre heat to avood changing weak glow plugs

Robbie has one of his excellent write ups on how to check glow plugs here
Towards the end he recommends persevering and replacing them rather than going down the FBH timer route and having just replaced all 6 of mine and noticed a distinct improvement in the low speed acceleration when the engine is cold I would second that recommendation. It has not really been cold enough yet to know whether it starts better.
I put some notes on how I got mine out without breaking them on this thread.
Good luck with whichever option you choose.

Could also be an injector problem.
Effects lots of makes of cars when 1 or more injectors bleeds off to much fuel so fuel pressure cannot get high enough to start.
A decent diagnosis tool will show you fuel rail pressure
If you put up your location there may be a member near by with said tool.

So far I have not used my glow plugs at all crank ign and it starts straight away.
I reckon you need to plug in a diag tool first

Why would you disconnect your glow plugs?
Unless you mean everything is still connected and you are just not pausing, in which case the plugs are still being commanded on and actively being used.
