it stinks that one spends so much money on a car and there is absolutely no protection to prevent a stone to break this radiator. instead of working with me to cover this under warranty, which i still had 4 months to go, audi of manhattan reduced it maybe $300 and i had to put it through insurance. the main office for audi couldnt care less. they basically protected their dealer partner in this. all it would take is an admission that a screen of some sort could protect a purchaser from an expensive repair. not good with customer relations and it is doubtful i would buy another audi.
