I vag-commed my A4 1.8T because of a reoccuring check engine light. It said I have cylindars misfiring.

What is the best solution? I am most likely going to take it to my local mechanic who works on European cars. But is there anything I could possibly do before or instead of this. What's the cost looking to be on this thing?

The worst part of all this is that has been getting very cold lately and my car struggles to start and wont start at all in the early morning.

Plus I just had a full service done last year, and now its acting up again, I am ready to sell this thing and buy a newcar.
