My car: BMW E46 2001, 330XI. Current mileage: 80,000. When should I change the timing belt? at what miles? How much will it cost in average at independent shop? I drive about 180 miles a week. Any answers would be greatly appreciated.When should you change BMW E46 timing belt? at what miles? How much will it cost?Vladimir is correct. e46's have a timing CHAIN. you will likely not need to replace it. I honestly have not heard of one expiring on an e46. other cars, yes.. but BMW designed the m52/m54's very well. oil supply is great for the engines, so you should likely not have any problems.
however, you may want to change your serpentine belts (accessory, etc..) those are easily accessible on and BMW Inspection II is typically done around 90k miles.

http://www.4ngiefest.comWhen should you change BMW E46 timing belt? at what miles? How much will it cost?You should always change the timing belt at 100K miles, you are getting close and might do it now.... I just had mine done on an 2004 Intrepid SXT with 78K miles on her, cost $250 for everything, and that is dirt cheap! Check with the shops, it shouldnt be over $500 for a BMW..... unless you can do it yourself then go for it.When should you change BMW E46 timing belt? at what miles?
