Here is some help I could find. It sounds complicated as for the fix. It sounds like a few modules will have to be reconnected, thus major damage if done wrong!

There could be few reasons for this fault. The most likely cause is the loss alignment between the DME (engine management) and the EWS control unit.

This would be the first place I would start by carrying out an EWS/DME alignment. I'm not sure which scanner tool you're using or even if it will be possible to carry this out on the tool you have but it's certainly possible on a BMW GT1 or DIS if you can get access to one.
If this does not rectify the problem start by troubleshooting the power supply to the EWS control unit eg fuse, power and earth to ecu.

But, taking a step back, the fault code in the majority of cases refers to a problem with the signal from the EWS (immobilization system) to the DME (engine management). Upon engine start the EWS will read a code from the key and then send an authorization code to the DME to enable engine start.

Digital Motor Electronics (DME).

The comprehensive management system for your engine: Digital Motor Electronics (DME) controls all key aspects of the engine's operation, ensuring optimum reliability, maximum performance and the lowest possible fuel consumption and emissions.

By managing key engine functions, Digital Motor Electronics (DME) guarantees optimum reliability, maximum performance and the lowest possible fuel consumption and emissions. Its sensors continually all factors affecting the operation of the engine. The data is then evaluated by a microprocessor and translated into commands for the fuel injection and ignition systems.
The DME system receives up to 1,000 separate items of data input per second, including engine speed, air intake volume, air temperature and density, coolant temperature, throttle position, accelerator position and vehicle speed.
DME verifies all incoming data by comparing it with the reaction of the rest of the system. If a defective sensor delivers unrealistic data, DME replaces this with preset standard values. If a spark plug fails, DME immediately cuts fuel flow to this cylinder in order to prevent engine damage.
DME looks after the electrical power system too, with sensors measuring the charge and condition of the battery as well as current electrical power consumption. By maintaining optimum battery charge levels and thus avoiding flat batteries, it prevents damage to the battery and guarantees maximum battery life, thereby helping to ensure the engine always starts readily.
BMW introduced the world's first Digital Motor Electronics system in the BMW 732i in 1979.

My last question will be, did you get any water damage to the trunk area. Water could have damaged a module, causing all of the problems. I will glad to hook up to my car tomorrow, & play around with DIS, to help you to the correct place. I feel more comfortable with DIS, do to the path it provides. Make sure to check all fuses to make sure it is not a fuse causing all of the problems. This will be an interesting fix. PM me if you do not know where to find the WDS drawings. Troubleshoot each module that has a "!" mark on the quicktest. This can be done at the top of the 2nd page after the quick test.

Good Luck!

all this started since i had the car jacked up and the car was on fumes,that was when i found the loose positive boosting terminal terminal under the hood i filled it to almost half full,unless its just a coincidence
i will wait for your info on the dis
Thanks

Does DIS say that the errors are "Fault currently present" or not present? Did you try to delete them & the re-appeared?
Just remember these cars store errors until they are cleared, even if the problem no longer exists.

i cleared them all,and when i go back they still re appear,i will spend more time today i just got the dis software yesterday,its kinda neat that you can test module like i tested the fuel pump and i could hear it running
i will try to test the eroors again,i will post back results

Thought about this a lot last night? You said that you jacked the car up? This could have put the car in protect mode from theft. I would go to the 2nd screen in DIS, got to the bottom, & click on the fault. This will put you in the test mode. Run the test plan for each fault to the end. Either take pics of the screen, or copy the screens for reference.

When you run the quick test, you can run the module with a fault from that screen also. Just click on the module, & run the test plan.

In the 1st post, you said that you had a problem with the positive lead under the hood. Di you by chance remove the positive lead on the battery? There is a link in that cable that will break if it is pulled on when removing. Use a VOM & test the voltage at the battery & under the hood to make sure that the circuit is not broken. Let us know the voltage at each end. I would also measure the ground wire to the body at the battery, & the ground connection at the wheel well. You could measure from there to a spot on the motor to make sure that the resistance is less than 1 ohm.

Give me an update after checking these items.

Good Luck!

After reviewing the schematics, I suspect that the DME & EWS must be re calibrated. I would test the EWS module 1st, to see if it has been disabled from jacking the car up. I jack mine all of the time, & had never had a problem. If the jack went down very fast, this could have disabled the EWS. The IVM, CAS, DME modules are all tied together. They must be calibrated, to be linked. I am starting to hope that the loose positive cable did not accidentally ground out, damaging the DME module. The directions below are written by BMW, so I have never done this. I would be very careful doing the test, & make sure everything looks good.


Car access system (CAS)

Functional description, see BMW Technology:

TIS --> Document --> SI Technology --> SBT Number 61 03 03 019
Service functions

Replacing control modules

The following points must be borne in mind when the CAS or the engine control module are replaced:
If a CAS control module is replaced, it must be ordered using the vehicle identification number (VIN). Following installation, that starting value must be matched to the engine control module. This starting value match is performed using the service function ”DME/DDE - CAS calibration” in the BMW diagnosis system.
If the engine control module is replaced, the drive-enable code must be transferred from the CAS to the engine control module following installation. This operation is also performed using the service function ”DME/DDE - CAS calibration” in the BMW diagnosis system.
After the calibration of the EWS and engine control module, these are mutually linked. It is not possible to replace one of the two control modules as a test.

DME/DDE - CAS calibration

In the case of a new engine control module, the service function ”DME/DDE - CAS calibration” in the BMW diagnosis system is used to read the EWS drive-enable code from the CAS and transfer it into the engine control module. This means that the engine control module and the CAS control module are mutually linked.

If the engine control module is already linked to the CAS, the service function is used to perform a starting value match. This means that the random code calculation between the CAS and the engine control module is calibrated.

A start match is required if there is a variance in the random codes caused by the influence of faults in the two control modules.

As of EWS4, a start calibration is no longer required.

DME main relay

The relay is driven by the DME control module.

Function of main relay:

Voltage supply to all components in the engine electrical/electronic system

Perceivable effects: - Engine does not run
Diagnosis instruction

Fault codes can be entered in any combination in the fault memory of the engine control module if the system voltage was too low due to battery discharge or due to failure or contact fault of the DME main relay.

If fault code 27C4 main relay is stored in the DME, all fault code entries listed below that were stored at the same km reading (mileage) are to be ignored and deleted. The DME control module should on no account be replaced.

It sounds like your DIS is not connected properly? Wasn't that the same error you were getting before? I would try & reboot the computer, then load the IFServer & Diaghead. The voltage & ohms look good. Make sure your firewall is shutdown, & reboot the computer.

The DME & EWS will have to be realigned & calibrated. It is possible that since the CAS is tied to both modules, that the antenna to the key is not working? Are you getting any faults for the CAS?

Have you checked all of the fuses in the fuse box under the air vent on the passenger side, to make sure one has not blown. I think the IVM would have been located there. If there is no power to the DME relay, the connection to the DME will not be made.

WDS needs a Java version earlier than 7 & it also needs to run on IE. What version of Java are you running?

They should be located in the engine bay under the cowl panel on the passenger side.

Well, that sounds like a win situation. I just hope it stays that way! Glad it is working for now, but who knows what might happen?
