20 Most Recent 2009 BMW 5 Series Questions & Answers

Hi Steve.I would be checking the fuses in all fuse boxes (there is one in the trunk I believe). Look for water ingress and corrosion.

check relay

Get your codes scanned . The engine light has a code attached to it which will point you in the right direction to fix the problem.

Depending on what year your vehicle is there are some service bulletins out there about the issue of voltage fluctuation causing the radio to lock up. Depending on production year of the vehicle they either need to replace the radio or install a over load relay that will cause the radio to come on delayed so it does not lock up. Still under warranty?

open hood , the cap turns off left loose right tight .oh it is on the top of the big black valve cover it is the only thing on there

find all of your answers on youtube , so much easier there than here , you can search for them instead of waiting

I quote some details from BMW's owners...Symptoms: Dreaded yellow triangle, ABS light, and CEL on. All other functions (speedo, tach, cruise control, trip computer, etc) working. Procedure: Pull the ABS controller out and disconnect it from the wiring harness. Mine is under a panel to the left of the glove compartment. Remove the wiring backshell so you can get at the wiring connections on the back side of the connecting plug (you need to be able to see the colors of the wires and get a Ohm meter probe on them). Using a Bentleys Electrical Manual find the connection diagram for the wheel sensors to the ABS Controller. The pin designators will most likely be wrong (they were for mine) BUT the color designators for each of the wires is correct. Example: Right Rear sensor is connected by two wires, one blue and one blue green. Connect Ohm meter across these two pins. NOTE: I wound paper clips around the probes to make a very small probe tip which helps. Write down the resistance reading. Mine was 3.08k ohms. Work through the other 3 wheels and write down the resistance readings. If any of the pairs is open (i.e. infinite resistance) you have a bad connection between the ABS Controller and the wheel sensor. You can then remove the affected wheel, unplug the sensor, short out the pins on the plug (not the wheel sensor part but the chassis wiring part) and if the ohm meter is still reading open you have a broken cable between the wheel sensor and the ABS controller. If the cable is good connect the ohm meter across the wheel sensor itself and if the cable still reads open you have a bad wheel sensor, replace and retest. Here is what I found. All wheels read 3.08k ohms except the right rear which read 4.4M ohms. This sensor was replaced during my rebuild exercise and it looks like they provided the wrong part. I replaced the part with a dealer item and retested. 3.08k ohms was read with the new part. Reconnected everything and the ABS light went out, the yellow triangle light went out. I used my OBDII computer interface to clear the CEL light and all is well again. Total testing/repair time: 2hrs and 35 minutes! Here is my theory. The "older" ABS Controllers (like mine) use sensors with the lower reisitance (3.08k ohm) while the newer Controllers use the higher resistance sensors (4.4M ohm). The part I bought was from a 02 E39! I can return it but I think I will use it to test my 00 528 problems first.Additionally, I suggest check charging system (alternator/power module/battery) has a defect that a professional BMW technician should look at, Most probably the alternator is toast.Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using Fixya, and have a nice day.

Is dont remember bad, this is the Speed Limit Display. That is a revolutionary new driver assistance system. The Speed Limit Display keeps the driver informed of the maximum permissible speed at all times. A camera fitted near the interior mirror permanently monitors the signs by the road as well as variable speed limit signs on overhead display screens.

If there is a sign indicating a speed limit in the wet, limitations at certain times of the day or restrictions applying only to towing vehicles, the intelligent driver assistance system, part of BMW ConnectedDrive, collects data from the rain sensors, clock and tow bar before displaying the restriction in the cockpit or, if requested, on the Head-Up Display.

Hope this helps; remember to rating this answer and leave a testimonila comment. Thank you for using Fixya.

BMW outputs codes in Hex format. The tool then reads the code and it may translate it to its own format. Some 29A.. code definitions here: 29A0 Lambda Sensor Post Cat Bank 2 Signal 29A1 Lambda Sensor Post Cat Bank 2 Signal 29A2 Lambda Sensor Pre Cat Bank 2 Signal 29A3 Lambda Sensor Pre Cat Bank 2 Signal 29A4 Lambda Sensor Heater Pre Cat Bank 1 Activation 29A5 Lambda Sensor Heater Pre Cat Bank 2 Activation 29A6 Lambda Sensor Pre Cat Bank 1 Signal 29A7 Lambda Sensor Pre Cat Bank 1 Signal 29A8 Power Management Network Failure 29A9 Power Management Battery 29AB Torque Request via CAN 29AE Tank Cap Code 29A8 it's a NETWORK management fault, related with tne main computer. Will need to visit BMW dealer to delete or reset it. I hope helps with this.
