Hey all,

As some of you may know, I purchased my 2008 E70 X5 4.8i last July. A month into owning the car, several issues started to appear one after the other. I just wanted to share my experience with everyone and how I went about tackling these issues myself. I chose to DIY fix everything not because I couldn't afford the repairs or had prior experience with fixing X5's, but because I wanted to learn about my car. Recently I've decided to tally up everything and was very surprised as to how much I've saved.

I am by no means, a mechanic. My only experience with working on cars is modifying(cosmetically) e92 M3's. My father is a mechanic though, and has given me some input on these repairs but he specializes in Japanese cars.

I encourage everyone to go about DIY fixing their cars because you get to know the car better, and the knowledge will carry on to other cars in the future. You'll also save a ton of cash.

Also if anyone needs some tips on these repairs, just let me know.
