Chain or belt on a BMW Z4?

My son-in-law's Z4 has just had to be recovered with a belt failure circa 55k miles and just short of the service when the belt is apparently due to be changed. The BMW garage (independant) advises this is common. Could you please confirm this a belt (not a chain) and if there is history of failure - at this mileage (or later)

The cam is chain driven. Chains can fail if they are not properly lubricated, but otherwise should last 200,000 miules or more.
