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.

Bmw will turn over but wont start

I would check the voltage the fuel pump first. They do go bad. You may be able to access it from under the back seat. Let me know what you find out and I'll try and help.

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 a 1996 BMW 328IS iwth 112k miles and the computer goes on and off without reason, that I can determine. When its on it works fine although there is a large looks like an ink block on the screen...

i have replaced my dme 3 times. water gets into that box and corrodes the dme inside.

remove your dme and clean the contacts on the circuit board with some alcohol and a tooth brush.

in addition, a smart move would be to cleans as many electrical conatcts as you can with a electrical contact cleaner and then apply some di-electric grease to each contact.

I've fix DME operations this way as well as intermittent ASC erors and even stiff steering for low speed operations.

Engine code 171

Ensure there are no wiring faults from the Digital Motor Electronics (DME) to the throttle motor using a break out box.
If the wiring is not faulty then replace the throttle motor, then clear the DME adaptation values.
Switch off the ignition for approx 30 seconds.
Turn on ignition and delete DME adaptations and fault code memory.
Push down on the accelerator pedal four times to wide open throttle.

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.
