While removing the center console and rear storage panel. I found 2 connectors that weren't attached to anything. One connector (shown connected to the bottom near the bottom of the storage door, not sure what this does) The additional two weren't attached to anything. They are sitting right above the airbag box there, basically right behind the e brake but in the transmission tunnel.

Any idea where this connects?

Hi - As I'm digging through the car looking for electrical issues since this car sat over 3 years outdoors. This is located in the drivers footwell, large wiring harness coming through the firewall, right above the dead pedal. This two pin connector was behind the carpet. Hoping one of you can take a look and see where it connects to. IMG_20240720_191529.jpg Attached Images IMG_20240720_191529.jpg (709.7 KB ..read more

Hi all - My first post as I'm now the owner of a 2004 Z4 2.5 Automatic. Basically the previous owner just wanted it out of his driveway as it was sitting for about 3 years, so I shipped it up to Maryland from Florida for ~$950. I've been using this forum and some other resources for some of my issues thus far that has gotten me pretty far on the roof not working. As I am waiting of the weekend to tackle the next part (removing the roof) I'm moving onto some smaller issues. The Hazard and Central locking button don't work. Initially I thought it was the switch, I ordered another one and remove ..read more

I'm in the middle of tearing my front end down to replace a defective control module. there is a lightbulb i would like to replace while im doing this. its the inner light with the socket. i cant find it as just a bulb because its not offered that way. I can't afford buying the part as its at least 60 bucks wherever i look. so my question is, does anyone have a replacement bulb that is compatible or a source for the part that is much cheaper. im ok with damage the socket a little to remove the bulb. When googling using "bmw 7170858" will bring up the part. i'll try to embed an image but i don ..read more

Top motor getting 12V but not working

The motor for the top is getting 12V but not moving. If I run wires from the battery to the to motor, it works. I'm assuming it's not getting enough amperage to activate the motor. Can this be a sensor or just bad wiring? I have already tested the sensor in the trunk ..read more

Hello, its been about 8 years since being on the z3 forum, I sold my 01 3.0 z3 back then but now looking into getting back to BMW and wanting a z4 face lift. Would like to get a 06-08 3.0 si, but will consider just the 3.0i. (automatic only). My questions are---Is there much of a difference between the years? I have seen some reports that the 07 had more problems? Also have seen that the si rides more rough because of the 18" wheels and sport package? Did all SIs come with M seats and was there an intermediate sport seat like some of the Z3s had? Overall what are problems to look for when buyi ..read more

Acquired a 2003 Z4 (2.5, Gas, US Spec, LH Drive) that had been siting for a while. Mistakenly fired it up before draining and swapping fuel, but it ran nicely, so that's good. Then it slowly lost fuel pressure. Pulled the filter, good fun, and would all siring in the tank had lost insulation. May explain some of the odd warning lights. Acquired a salvage tank, as I was unable to see how to get the other component in the LH tank lobe out of the tank. Now attempting to drop the tank, and determining that the rest of the car was built around it. Any experience dropping the tank available? I have ..read more

Can I operate the convertible top while removed from vehicle?

Hi everyone. I'm new to this forum. I've had a Mercedes-Benz indy shop for 15 years but occasionally work on certain BMW models. I currently have a 2003 Z4 (E85) Convertible in shop that had a hydraulic leak on the right side top hinge. I've removed the top assembly from the vehicle and replaced both top hinges with rebuilt units from Top Hydraulics. I'd like to refill and purge the system by operating the top repeatedly while out on the shop floor since the reservoir cannot be filled when the motor and top are installed on the car. This would also allow me to check for any hydraulic leaks. C ..read more
