Question about 2007 BMW 525xi Sedan

1 Answer

My BMW 520i '93 Service indicator showing only word 'Code', at same time, speedometer, tachometer, fuel gauge and temperature gauge dead (zero position). It happens when I drive on the road. Engine and other functions doesn't trouble. I've checked all fuse (front and back), all in OK condition. I've tried to disconnect then connected again : front ECU (2), 2 back modul, 2 connector at instrument panel (speedometer). It doesn't resolve problems. Thx

You need to perform a static discharge on the vehicle. Remove both cables from the battery and touch the two cable ends together(you may need a jumper wire) for a few minutes. Reconnect the cables to the battery and check it out.

SOURCE: BMW abs light and speedometer not working

I would replace the Vehicle Speed Sensor (VSS) at the transmission 1st, also who advised the PCM (computer) was bad? a Jag dealer? I think they are guessing on that, computers rarely fail, maybe 2% of the time if that.

Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car

The odometer is not working on my 1999 navigator. It just says 0. What could be the problem?

Odometer The instrument cluster receives odometer rolling count status from the PCM-engine computer and stores the mileage in non-volatile memory (NVM). When the instrument cluster fails to receive the odometer rolling count status for more than two seconds, the odometer display will show dashes.

HEC Dealer Test Mode
To enter the HEC Dealer Test Mode, depress and hold the instrument cluster SELECT/RESET button and then turn the ignition switch to the RUN position. Continue pressing the SELECT/RESET button (5 seconds) until tESt is displayed in the odometer. The SELECT/RESET button must be released within 3 seconds of the odometer displaying tESt to begin the dealer test mode. Depress the SELECT/RESET button to advance through the following steps until dtc is displayed. Depressing the SELECT/RESET button will display any continuous DTCs stored before proceeding to the next step.

The instrument cluster speedometer, tachometer, fuel gauge, amp gauge, temperature gauge, are not working while engine is running. 2007 Peterbilt 379. What is the problem? What do we need to look for?

look for a common connection like a bus bar and fuse for the dash
check for a broken ground wire from the cabin

My Tachometer works ,but my speedometer doesnt ? In mornings when cold it hesitates and misses, once it warms up it does great. Why ?

The hesitates and misses is probably a chock problem, especially since when it warms up, it does great.

Since you weren't very specific on your indications, I thought a general troubleshooting guide might be helpful to you. But you might want to look on ebay for a shop maintenance manual for your vehicle if you plan on keeping it for awhile and doing your own maintenance.

This answer is applicable for many BMWs in addition to the one listed below.


The tach and speedo work most of the time, but sometimes work sporadically.

Here is a write-up on the initial steps in tracking down a speedometer and/or tachometer problem.
Applies to: E23, E24, E28, E30, E32, E34 with speed sensor units mounted in the differential housing cover.

1) Speedometer - The speed sensor may be faulty. The sensor is mounted in the differential cover. Remove the harness plug and remove the sensor. Clean the sensor and measure the resistance (should be 0.0 Ohms). If there is any resistance higher than 0.0 (zero Ohms), replace the sensor. If the resistance reads correct, reinstall the sensor.

2) The wiring at the connector plug for the speed sensor (in the differential housing) may be faulty and corroded .... pull the boot back from the plug housing and inspect the wires and the pins.

3) The actual speedometer and/or tachometer head may be faulty. It may have a loose connection within it or a cracked circuit board.

4) The speedometer or tachometer head may be loose on the main instrument circuit board (do the gauges change or move if you smack the top of the dash, above the gauges?). Remove the instrument cluster and check the mounting of the speedometer/tachometer to the circuit board. See the attached issues of our Fast Times newsletter for assistance in removing the instrument cluster, on E30 3-series models (see the articles on replacing the PC board and replacing the odometer gears for info on the removal of the instrument cluster).

Fall 2005 Fast Times Winter 2004/2005 Fast Times
DIY E30 PC Boards DIY Odometer Repair

2005_n405_newsletter.gif 2005_n105_newsletter.gif

5) The plug that carries the impulse signal into the instrument cluster may have loose contacts. The plug for the speedometer signal is located on the driver's side of the back of the instrument cluster (on the E30 chassis). If you remove the lower dash trim panel (the one above the driver's knees), you can reach up and touch the plug. It is in a vertical position and has up to 26 wires in it. If you wiggle the plug, while driving, and the speedo comes & goes, you have loose contacts in the plug connection.

6) You may have a problem with the service interval PC board and it's NiCad batteries. If your oil change and service interval lights can not be reset (or will not stay reset for an appropriate time period), the PC board is likely faulty. This can affect the various gauges, including the speedometer and tachometer. If the PC board is faulty, I would suggest replacing it (after checking the other areas noted above). See the attached Fast Times newsletter article on replacing the service interval PC board.

In your specific case, I would suspect that you need to replace the service interval PC-board, if your service reminder lights can not be reset or do not stay reset.

Speed ometer in the dash gives inaccurate reading while the digital reading in the widnshield appears to be correct. Fuel gauge has rapped around forward and temperature guage is off.

The problem here is your "Stepper Motors" are failing in the Instrument Cluster. If your Vehicle has "LOW MILEAGE" it may still be covered under factory warranty. Check with your Dealer first! If not covered under warranty, most reputable Speedometer Repair facilities can service it for you. All "Stepper Motors" in the Instrument Cluster should be replaced at the same time as the OEM versions are prone to ultimate failure.Typically, there are 5 or 6 dependent upon whether or not you have a Tachometer. They are: Speedometer, Temperature, Oil Pressure, Fuel Gauge, Volt Meter and Tachometer. The replacement part must have X25 168 where the X indicates an improved model.

Dashbord instrumentation Non functional for Japan imported FB14 Sentra

Located behind the instrument cluster
It is attached to the rear panel of the cluster.
input from battery is 10Volts, it regulates down to 5Volts
Any higher voltage inputed will overload the capacitors and resistors will burn,
Also check power distribution center, under hood upper motor area in drivers corner, check all relays and fuses.
Before you rip in to the dash check all ground wires, battery to ground, harness grounds, driver/passenger mid fram rail, Fuel sender is also ground to top of gas tank. IF ALL gauges do not work, that just leaves voltage regulator and/or cluster is malfunction,
