Newbie with '05 X5 3.0i issues...Help

[bryans]

I'm a newbie and just recently picked up a '05 X5 3.0i w/premium package. The car is preowned with only 24K on it. Meanwhile, I recently noticed a few things that have got me concerned and will be bringing into the dealer on Monday. But I'm hoping that others here may have experience the same issues and provide some insight what they may be.

1. At low speeds I hear a intermitant bump/grind that I believe is coming from the right rear area. It almost sounds as if something is knocking into the wheel well.

2. Both the front and console power outlets are not generating and juice.

3. When I make a hard right hand turn I hear a clunk.

4. In auto mode, should the Xenons be staying on in the morning...When I leave, the sun is up. Can any one tell me how the auto mode works?
- time of day
- direction of sun light

Other items I intend on having them look at are as follows:
5. Some times I get a funky smell from the heater
6. Re-adjust the auto door locking mechanism not to lock. Is this possible?
7. Right now I have 17"s, but come summer I'm going to want to upgrade to 20". Does my X5 support staggered wheels? Any recommendations on size?

Meanwhile, are there any other little, or big, idiosyncrasies of the X5 3.0i and/or 2005 year model that I should be aware of.

Or if you you've had similiar issues, how did you resolve them?

BTW...This forum is fantastic! Thanks.
