This is a problem for the GTi I own but its not a world ending problem. The RS4's of Audi in 2006 etc had major problems as well as the early R8 4.2's. If you have a Mk6 GTi like I do you will need to clean this around 60-100k miles. Sucks overall but its not that big a deal. There are ways to mitigate this by driving with higher revs occasionally but nothing can prevent it at all. Seafoam nothing.
Quite a few cars are affected but changes to injection design have been made especially by VW to prevent this.
