OP, so who are you depending upon that the car needs these levels of repair? Are you taking the dealership's word for it? Are you investigating on your own? What is you level of knowledge about cars in general? Are you being anal about some of them?

Dealerships are notorious for diagnosing repairs that are not necessary. A valve cover gasket leak for instance, is it a simple weeping leak that a wipe from a rag will keep it in check, or a leak that is dropping an amount of oil on to the exhaust manifold and making an intolerable oil smell. There are millions of cars on the road that have weeping valve cover gaskets. Eccentric shaft sensor, did it fail due to the leaking valve cover gasket, or did they just replace it after the VCG was repaired?

My car developed a squeak in the steering wheel. I left it alone and it eventually went away. It sounds like the dealership is chasing a bunch of problems that it sees $$ for. Belt tensioner, a somewhat common issue, and a cheap fix. My car has a weeping oil pan gasket. I could fix it myself, but why? It's a little leak, I wipe it up every oil change. Yeah, it's a bit of a mess but I can keep it clean for a lot less effort than pulling the subframe, supporting the engine, and replacing the gasket. And I have a lift and complete auto shop at home. What I don't have is a lot of free time to do car work unless it is absolutely necessary.

In my 27-years of BMW ownership, what I've learned about the brand is that BMWs tend to fix themselves (like my steering wheel squeak). Scan your car with a BMW scan tool and you'll find several codes that come and go and don't mean anything. Periodically my car will show that the BMW Assist is not functioning. Probably a software bug of some sort, but I let it be. A scan of the car will show the Bluetooth system didn't function at some point. Probably related to the BMW Assist system not working. Yeah, once and a while my cell phone won't get connected to the car, but who cares.

The point I'm making is all cars have small issues that may not really need attending to. Being a bit less anal about them makes life easier. The other thing I've learned over the years is most BMW owners are anal retentive and make their BMW ownership a lot more stressful than need be.
