زين الشيخ إذا تفهم بالإلكترونيات بعد ما تفتحه قولنا وش العطل لانه القديمه لازالت عندي إذا تتصلح أصلحها بس علمنا لو تعرف
Here is something I wrote for the E39. I wouldn't expect it to be much different for the E46. Let us know how it works out.
Remote key / fuel door actuator problem write-up
Both master keys remote functions don't work, but their at door functions work normally.
Check if fuel door latch is working. Lock/unlock car with key at door and check if fuel door is locking and unlocking.
The fuel door actuator shares the same electrical circuit as the key remote functions module (FZV, right c-pillar). If the fuel door is not functioning properly, then the circuit fuse is most probably blown.
On my car (528i 2000) the fuse is #53, 7.5 mA, and is located on the fuse bank in the trunk passenger side compartment; above battery. A fuse list is on the inside of the compartment door. It lists the fuses in physical order. #53 is the 8th fuse from the front and is designated "Central Locking System". Pull out the fuse and look closely at it. You'll find the center of the wire to be missing (burned).
The fuel door actuator is a problematic component. When it starts failing it will draw a high current and short the fuse. Replacing the fuse will work, but only very temporarily, as the actuator will short it again. The solution is to replace the fuel door actuator.
Parts: BMW fuel door actuator, 67-11-8-352-168, $35. 7.5 mA ATO fuse; a spare can be found at the glove compartment fuse bank (unscrew 2 clips at compartment inside roof).
Tools: T-20 Torx bit driver. Pick tool w/ 90 degree angle at tip.
The actuator can be found in the trunk passenger side compartment; below/front of fuse bank. It has a black metal bracket/plate covering it, and an electrical connector/cable on the back. Its replacement might look simple, but it's quite tricky. The actuator connects to a long apparatus on the front which leads to the fuel compartment. Removing and replacing the actuator necessarily disturbs the apparatus, and reconstructing the setup is difficult, particularly due to space constraints.
Remove the electrical connector by prying out the side clips. Remove the 2 middle screws mounting the actuator to the bracket. Remove the 2 top and bottom screws mounting the bracket to the car. Pull back the bracket and actuator so you can access the actuator front.
A wire with an end anchor goes through a bracket front hole and connects to the actuator plastic rod. The wire anchor is snapped into the actuator rod end clip. The anchor is difficult to remove. Pry the pick tool between the actuator rod clip and the anchor. Wiggle the pick to insert deeper. Pry/wiggle the anchor out.
Replace the old actuator with the new one.
Insert the wire anchor into the new actuator rod clip. It'll need some force.
There is a white plastic clip on the wire in front of the bracket. The clip needs to be inserted/snapped into the bracket wire access hole.
The front of the wire is connected to one end of a long thin plastic rod. The fuel compartment has a medium length flexible rubber tube protruding from the back of it. The plastic rod is to be inserted into the rubber tub and appear into the fuel compartment. This is quite difficult since there is little room to work, no visual access, and the tube is quite narrow and flexible. You can initially feel back into the compartment to find the rubber tube. Then pull back on the bracket/actuator so the plastic rod can be pulled back. It's important that the plastic rod be further back than the rubber tube end, so a direct insertion can be attempted. By one handed feel, insert the tip of the plastic rod into the rubber tube. Go slowly, the tube will easily bend and you'll need to retract the rod. Wiggle the rod some and insert slowly. Eventually you'll be able to insert the rod through. You'll see its tip appear in the fuel compartment.
Remount the actuator onto the bracket, placing the screws forward on the screw slots. Mount the bracket onto the car. Reconnect the electrical connector to the actuator. Insert the new fuse.
Test the remote key functions. Check the fuel door function. Initialize the keys if necessary.
