I have a 2001.5 s4 and within the past few weeks my electrical system has started going crazy.

First, the instrument cluster display is now blank when I'm driving (no longer shows my miles per gallon, temp, etc). However, I know the screen isn't dead because it shows when doors are open, etc. Any ideas?

Second, my front door speakers (factory Bose) randomly started to rattle as if they were slightly blown, but theres no way I blew them out. I've heard there are lots of problems with these speakers, so I assume its an amp issue. Anyone know where/how I can get this fixed, and approx how much it will cost?

Third, when I start the car up, I get the 'Service!' alert. This is particularly strange because it used to say "Service in 800 miles" about 75 miles ago. I don't even know what that means. Does it mean I need an oil change? I had my oil changed about 2500 miles ago so I don't know.

All of these issues seem to be electrical, but I really don't know much. Any help would be greatly appreciated. Thanks!

 

Wow man take it easy there is nothing wrong with your car

The display can be reactivated by pressing the reset button under you wiper controls on the bottom side of it

Im not sure about the speaker issue

For the service light, it means nothing, just needs reseting, to do this push in the right **** on the cluster turn the key to the on position and push the left side one
