2012 2.0 TDI 140 - Starting start-up issue problem

[Ross62]

Normally starts with one press of the key but noticed in hotter weather it does not start first time. Press the key and it turns but dies, try again and it takes 6 or 7 cranks to fire up but then runs normally, other wise runs fine.

Anybody else had this or have a solution with going to dealer?

Thanks.
