td5 defender knocking at cold startup

Hi, i want an advice from you: my td5 defender (2004) have an horrible knocking sound at first 5-6 second from cold startup every morning.it's like a tumf tumf tumf, it comes out from bottom of the engine.
I'm using a Castrol diesel magnatec 5w-40 oil and this have 2000km on it, oil filter is new, and the level is ok.
What could be??

It sounds like diesel knock,

only thing i can say is test your glow plugs are working

and compare it to someone elses td5 or ask someone more experienced to listen to it

TD5s only have 4 glow plugs, so could be the other cylinder. how bad is it

here there is the recording of the strange sound,keep attention since 0:12..(raise speaker leve) [nomedia="http://www.youtube.com/watch?v=pL8rOtCWBx0"]YouTube - Defender td5 problemi accensione[/nomedia]
