Based on the low mileage the belt has actualy done, I would think that you have a very strong argument for a warranty claim. The only fly in the ointment is if something has caught the belt and caused it to fail.
Hell yea.
On start up from cold the 07 Z idles at about 2k for between 30 secs and a minute. Nothing compared to the Lambo but still noisy enough to make people look round. I drive till the oil temp rises then punch it.
Has the 07 MY got an oil temp read-out then?
