Should the dealer pay for my car's new timing chain?

My local BMW garage has informed me that my 2010 318i Touring with only 29,000 miles on the clock needs a new timing chain and vanos unit. Is this common and should BMW cover the cost, even though the car is no longer under warranty?
BMW will cover the cost of the VANOS because there is a VOSA recall on this. See the E91 3-Series car by car entry.
