I have every sympathy with your problem. I have just purchased seat leon on the trip home the engine management light came on. Reported this to garage who turned it off and told me to see what happened. When it rained water poured into car and light came on again. They have fixed light but not cured leak, after reading your post I have got nasty feeling that i have same problem, they will also not take it back. I have paid for legal protection from home insurance company, have you checked that you didnt get that with yours some companies just add it on automatically. Good Luck.
