Well if the car is actually cranking but just not firing up usually the dme and the ews needs to be "mated" or "synced" together again. The ews is the immobilizer and it has "rolling codes" that have to matched when starting with the last code that is in the dme memory of when the car was last started. Take it to BMW and have them to sync them. Car will start right up.

PS...also check your CRANKshaft sensor as well. It provides a pulse to the ignition coils to fire also.

have throttle body checked also the MDK throttle motor,
make sure that the dealer has followed service bulletin 12 07 99 for procedure to replace the MDK throttle motor
also have them check for codes,here are some codes,
it could be an expensive job,have them check everything,it is most likely the throttle motor,,throttle body is 600 if they switch it,dont let them do it without checking throttle motor,

Where is relay for fuel pump on 1992 bmw 325i


The Bentley Manual shows the fuel pump relay in the box on the passenger side of the car under the hood. Looking toward the drivers side the pump relay is the second on from the passenger side. It is fuse #23. Looking at the bottom of the relay the pins clock wise from 12 o'clock are 30-87-85-86. The third one from the passenger side is the main relay. It is usually white. "The main relay is energized via the DME engine control module and supplies power to many of the DME components and subsystems, including the fuel pump relay. If this relay is faulty, the engine will not start."

95 bmw 325i cranks but wont start.Has fire to plugs,checked fuel pump fuse, relay and main relay,no ground to fuel relay socket,no hot or ground going to fuel pump,,suspect DME ??? Was running fine un


Try to disarm the alarm system first,if that doesn't work,try your spare key,if it works the key is faulty.if this fails,put it on diagnostic machine.,since it can be EWS.

Porsche 944 not starting checked dme has fuel checked coil is ok can't see spark tho however if the car is bump started it runs spot on


have a load test done on the battery as this is an indication of a bad cell ( not enough current to spin starter and supply the ignition system.) Check battery terminals and posts are shiny clean and tight.

05 BMW X3 can i install a use dme and and program it using ISIS diagnostic and programing soft ware


No, the dme is coded by vin, the car would not start if you tried to program, you could perhaps snag the ews and lcm from the same car you got the dme from. But the. You might have a issue with the new lcm trying to update mileage to the old Komi. A lot less headaches to just order one coded from BMW why do you think it needs a dme?

I have the check engine code 1624 on my 2000 BMW 323i. What does it mean?


P1624- Pedal Position Sensor Potentiometer Supply Channel 1 Electrical.
The Siemens MSE43.0 Engine mamagement module is used on more than one model. The different meanings of the P1624 are based on your model.

The P1624 referenced here is for the MS43.0 engine management module with a note for M52 engines (323 / 328) that it is a coolant temperature below thermostat regulating temperature. You should have a M52 engine.

The MS42.0 engine mangement does not list a P1624 code in the Bentley manual.

The fault above cold be set due to the following:· Break/open in the wiring from the DME to the throttle motor(MDK).· The actuator or potentiometers inside the MDK could be contaminated.SOLUTION:
(If any of the faults listed are set) · Using a breakout box check for an open or short to ground in the wiring from the DME to the MDK.· If the wiring is intact then replace the MDK, then the adaptation values in the DME must be
cleared. Failure to do this will result in reoccurring faults.· Switch the ignition off for 30 seconds.· Turn on the ignition and delete the DME adaptations and the fault code
memory · Press the accelerator pedal to wide open throttle(WOT)4 times
MDK- motor driven throttle valve.

CHECK ENGINE LIGHT ON, WHAT IS DME CONTROL MODULE


Digital Motor Electronics (DME) is a microprocessor-based system that controls the ignition, the fuel injection, the oxygen sensor and numerous ancillary functions. DME provides raw data to an on-board computer that uses an alphanumeric display to provide you with information such as the average fuel consumption, the distance you can still cover with fuel in the tank, an average speed, outside temperature and more.
In the industry, DME is often referred to as the Engine Control Unit (ECU), under the heading of Electronic Engine Management Systems.
DME operates by continually monitoring such factors as engine temperature, speed, intake airflow, exhaust gas composition, and even the altitude. DME then literally fine-tunes the engine hundreds of times a second to provide maximum performance and efficiency. DME has a fail-safe program in the event of certain electrical faults. Current DME versions also have on-board diagnostics (OBD).
