I asked a service rep at Classic BMW in Plano that question and he said "never". The 740 has a timing chain, not a timing belt. Cars with timing belts usually have to change it every 80-100k miles, but this does not apply to timing chains. If your timing chain is intact, you should not have to have it replaced. Chains do not stretch or wear out. More likely, if you have a E38 (1994-2001), the timing chain may rattle, which is NOT an indication of a problem with the timing chain. There is a timing chain tensioner that loses its ability over time to apply proper tension to the chain, and that is a relatively easy and inexpensive replacement. Another well-known problem is that you may eventually need to replace the timing chain GUIDES, which is plastic and can wear and break off over time.
In some BMW's you will find a second fuse box in the trunk, behind the carpet on the right hand side wall. This applies to BMW's with the battery located in the trunk, on the right hand side. You have to look UP, near the top to see the fuse box. This MAY NOT apply to all BMW's tho, but definitely E38 7 Series, and E39 5 Series have a secondary fuse box in this location.
if the car runs like crap then you could try replacing it. see if it is faulty by unplugging it. the car should run crappier when you do this. when you plug it back in it should be happy again. you really don't need to touch the MAF unless it gets really fouled by some oil, but even then it has a heated element which will burn off the oil. get a book to your car here, only certain years: http://www.germanautoparts.com/Books/BMW. if you want to clean it out it may help but the MAFs last forever unless they've been through a hurricane or drowned in some water.
