1997 z3 radio works but no sound from speakers

You have air in the clutch system. Check the fluid level in the reservoir . Check for oil leaks at the slave cylinder ( replace if there is oil ) Have the system bled . IF you have fluid and the air comes back then replace the clutch master cylinder as the air will be bypassing the piston cup from blockages in the ports.

The brake lamp circuits on your 1997 BMW Z3 are pretty "old-school" and straight forward. Fuse #46 (15 Amp), located in the Front Power Distribution Box at the left rear side of the engine compartment supplies battery voltage to the brake light switch via the VIOLET/GREEN wire going into the switch. When the bake pedal is depressed, the voltage leaves the brake lamp switch on the BLUE/RED wire and supplies power to all of the brake lamp bulbs.

The brake lamp circuits do branch off and go to several control modules. This is ONLY for module INPUT to tell the module that the brakes are being applied. These modules include:
> Transmission Control Module
> Cruise Control Module
> ABS Control Module
> Slip Control Module

The ONLY way that any of these modules could be affecting the operation of your brake lamps is if there is an internal short to ground in the module that is causing the brake lamp fuse to blow.

If NONE of your brake lamps are working, the most likely causes are:
> Fuse #46 open (blown)
> Defective brake lamp switch
> Bad ground connection at ground G400 (Left side of luggage compartment)
> All 3 of your brake lamp bulbs burned out.

Yes, the BLUE/RED wire could be broken as well, but I would check all the other things listed above first.

Getting the code to unlock the radio requires access to the factory data base, that is restricted and we do not have permission. You will need to contact the dealer for help with this. The original owner was given this code.

in this case you need ot contact the dealership and ask them since it is dependent on the VIN#. Also if you have ALL the information from when you purchased the car, the owners manual may have it written down in it somewhere, but it will not be printed, it will be hand written. Its a 4 digit number.

everything keyless runs on frequencies if you removed the radio most likely it removed the keyless entry too especially in a beemer

it probably does. you will have to contact the dealer and see if they have any advice on what you can do to fix it.

most new BMW's the fuse block is located behind the glove box. There should be a pair of twist plastic fastners at the back of the glove box, twist and remove the plate and you should find the fuse box and fuse locater list.

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

Hey,
take a look at www.airbagmodul.com

They're working in Airbag-Simulators, Occupancy Sensor-Simulators and Seat Belt-Sensors.
