What problems should I look out for on my 10 year old BMW?

I own 57 plate BMW 335i M sport Touring with 65k miles on the clock. We are the second owners of the car which we acquired from a main dealer 4 years ago. We do 5k miles a year hence the choice of a fun petrol car over a frugal diesel. The car drives well and all maintenance is through a main dealer. As the car is 10 years old what sort of maintenance problems are likely to come our way over the next few and can we expect some big bills?
Get the timing chains and tensioners carefully checked. Wise to replace the turbo bearing oil feed and oil return pipes because they could be partially blocked with carbon. Wise to replace coolant and brake fluid as well.
