Emissions workshop and EML light flashing

Hiya,

Now the weather is getting a bit cooler I am having the same problem I encountered last winter. On cold mornings after a few moments of driving my Golf seems to judder a bit and the warning Emissions work shop flashes up as well as the EML light. This usually either goes away after a few minutes, or goes once I have turned the engine off and restarted.

Any ideas what this might be? Im booked for an MOT in a couple of days so not sure whether this might effect it?

Thanks so much

What were the fault codes stored when you did the logical thing and had a code read done last year and since the problem came back?
