I have had my 2010 octavia for a month now and have noticed a very small misfire when first starting in the morning. 

It Is only slight but it is noticeable this goes away after half minute or when I start driving but looking for ideas what it could be.

The car was put on vcds for something else a few weeks ago and nothing was brought up. 

Could it be a glow plug faulty or would this have come up on vcds?

It is normal  it has to do with the valves until they get in normal pressure  working state, mines do  this since new when cold especially in winter  , but no problem anytime at all. 

 

Many thanks

Still getting this misfire when cold. Could it be something else apart from valves. Gloe plug etc ?
