When was your first "OH $!*^" moment with your X5?

[TwinTurboGTR]

I wanted to start this thread because of that post about which X5 is better and there was an eery consensus of "Fixing" something on out X's I wanted to get a thread going and read others stories about their X. It can either be the first time they were gonna DIY something on their X; whether it ended good or bad. Or if you go yourself half way into a job and all of a sudden you have a brain fart and cant remember where anything goes anymore. Or maybe when your hummin along and then you see a dashboard full of lights, or a clunk, or maybe pieces of your motor flying out. Or shortfalls you have seen with your X that you wouldn't have otherwise anticipated.

Hopefully this thread will be funny and helpful at the same time to remind people about procedures and how they should be followed.

I'll go first.

My first moment was when I first got the 4.4. I thought it was great, I mean hell it was a Bimmer. Anyways I drove it everywhere and thought it was the best thing ever. I am a person that enjoys the snow so I was excited for the first snowfall. I mean AWD, in a SUV, this thing will be a tank, right? First snowfall was about 3" and I was excited. At the time I just had the ugly style 58's wrapped with the Michy Energy tires that were NEW... Drive out of my development to the first stop sign... Completely just trucked through the stop! All 4 brakes locked up doing 10 MPH and I was up another persons driveway. It was a miserable day after that. It was so bad that I had to turn the hazard lights on I was going so slow and at the time I was in high school, 30 minutes late and I only lived 8 minutes from the school. Needless to say I discovered Snow tires real quick. Now it's unstoppable.

My second moment was when I did the VPG... Seeing half of your motor on the garage floor and seeing all that space in the bay was a bit intimidating. That and it was so oily and greasy under there that all my nice labeling with tape and everything... yeah wasn't legible at the end. Thank god I was born with common sense though. After putting it all back together, only to be too excited to see if the car would start... And forgetting to put the battery cables back on. When the X did nothing... you know that feeling in the pit of your stomach that you get when you can just envision the amount of money you will have to hand to someone else to fix your F&*^ up? Then my common sense came back and reconnect the battery and all was fine.
