V W beetle 2.0 auto petrol - Difficulty starting on cold mornings - distributor

Hello,

the colder the engine of my wife's beetle, the more difficult it is to start. When warm it is ok but it is very reluctant to get going especially on cold mornings. Once started it runs perfectly well. The tick over speed once just started is a lot slower than it used to be.

An ideas Thank you
