When the car is stationary. Push down on the back (Boot or TRunk) as hard as you can a few times & listen for the squeek. It's more common in the rear suspension from my experience. It sounds like the bushings are gone or worn at the top of the suspension struts.
That's if it does squeek. You might not need your suspension replaced just the bushings as they are normally plastic.
Try doing the same by pushing down at the front of the car also as it maybe happening there too.

Sounds like either you have a clogged fuel line and or clogged fuel filter or the fuel pump is failing. What happens when the vehicle runs the fuel pump heats up, as it heats up it produces less and less fuel for your car. Eventually ti stops working until its cool again on faulty pumps. Given the age of your vehicle I would say you need to replace both pump and filter.

Why after driving my 2006 528i bmw say about 30 to 40 min when I turn the car off and try to start the car up again it will not start. but if I wait about an half hour the car starts right up

I believe the 5 series has the same IVM module.

2006 BMW 750i - IVM module - Replaced on 5th January, 2015
Car would no longer recognize remote starter key and I could not start the car. Lights on in dash, but no noise, no starting.

Inittially thought one of my remotes were no longer good, then thought maybe it was because I had my iphone too close to the key..... None of my initial diagnostics were right, it was the IVM module. I often waited 15 minutes, then it started; then finally one day it wouldn't start at all.
Apparently the Integrated Voltage Module (IVM) has a relay in it that fails over time. The car began intermittently not recognizing the Remote (key), then failed completely. Replaced the IVM module and the car started immediatly and has started everytime since replacement. Part cost $127.US + tax at BMW dealer or $80. on line. Pretty cheap for what it has (9 connectors, a printed circuit control board, several relays and multiple fuses). Easy to replace and it took 1/2 hour to replace and is located under passenger side cabin filter (under the hood) on the 750i - there are nine (9) connectors to remove and re-install on this module. Mine was an original part Manufactured on 21 January, 2005. Tools needed: one Allen wrench and a # 10 socket. See YouTube for video.
Apparently Dealer will replace for close to $500. You can do it yourself.

Hope this helps!

1994 BMW 525 radio displays "CODE WAIT" after I put in the code numbers

You need to wait 1 hour before attempting to put the code in. Either the ignition needs to stay on 1 hour or drive it for 1 hour. If they key is turned off before then, you will need to start again.

My 92 bmw 735i's battery died last week and it has already been replaced with a new one. It started up fine since then. Today, it wouldn't start at all without a jumpstart. I dared to drive out of my drive...

Sounds like the battery is not holding a charge, or something is draining the battery. You can check this by making sure everything in the car is turned off, disconnect the positive terminal of the battery, connect a test light to the battery terminal and the other end to the battery cable, if the test light lights up, something is drawing on the battery. You can pull one fuse at a time to try to determine what curcuit the problem is in. Most parts stores will test your battery, takes a couple hours.
