Passat B6 Hard to start if not driven more than 13 hours

Hello,

I hope that someone can help me with issue that I'm experiencing.

My Passat B6, 2006, 2.0 TDI 140hp have trouble starting when it's not driven for around 14-15 hours.

Basicly, It's cranking around 9-10 sec before motor start to run (battery is checked and it's ok).

But when I starting my car after I finish with my work (8h) it is starting without any issue.

Weather is warm so cold mornings are not the issue.

My mechanic is not sure what is the cause of issue.He checked with diagnostic tool and find no error.He stated that injectors and glow plugs are OK.

Any ideas what could cause this issue?
