I've just bought a bm740i rhd ..the suspension makes lots of noises over bumps.what can be damaged

Iwent to start my car today and unlocked itgot in it and went to start it up and then the car just went completely dead, the dashboard went off my key wont lock or do anything.

I have had the car for 10 years and lately it is performing very badly in it just getting tired or should i be looking at another problem. The S drive still is peppy. i have not changed plugs in 4 years and 40k miles but it seems to run fine.

recently changed the intake gaskets and did a tune up. Now its not idling smooth. Took it for a long drive and drives great and idles good at stop lights. checked for vacuum leaks and didn't find any.

I just replaced my battery in my 94 740iL. It drove fine for about 2 days, 65 miles worth. However, now on day 3, all the electronic control lights are coming on again, and when I attempt to turn, the anti lock system kicks in and wont allow me to make a sharper turn, its quite scary when your in a lot of traffic. It only happens when I try to turn. When I am driving straight, the suspension leveling warning comes on the dash display, but the other lights stay off. I am completely out of ideas, and I am terrified that it is going to be an extensive fix. Someone please help!!

The gages light up but the blower never turns on I checked the fuse and it looks good so whats causing it not to work
