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!

Check your manual.

It should be in your Manual, read it very carefully.

you cannot check the oil a light will tell you as and when it needs oil which is a dealer only type job ,so its a expensive business .sorry to bring you the good news

The radio volume goes up when you give it Gas this intern hides engine noise. This is very common with higher end cars
There is a adjustment on the radio that will set the level you wish the volume to go up when accelerating, its a nice factory option to have there is nothing wrong with your BMW.
