Hello! My name is Vick. I'm from Romania (Europe).
I've got a 2002 VW Bora TDI ALH (also known as Jetta, in U.S.).
This is my first VW, and I am very surprised with what offer this car
At the moment, I have two problems: error P1556 (limp mode) and problem with cold start.
But with your help, I suppose I'll fix them

The cold start could be as simple as a timing problem. Look through the FAQ article on fixing P1556. It's a common problem.
