UK Car Repair Questions? Ask a Mechanic for Answers ASAP
main request is as stated above. I try to be more specific: After removing complete engine and wiring loom from the above car the engine won't start. "Startfreigabe" missing. Some diagnose tools available. Original key switch, steering lock and clutch sensor are installed.Whole dashboard iS INSTALLED. Some person understanding the logic of Bosch EDC17 and the BMW Mini CAN bus system would be very good. I am happy to give any further details if required. XXXXXX. regards Bernd
hi, if you see a chance for an answer I am happy to wait. Please keep me a little updated and please try to communicate with your "main system" so that this time no one will process my refund unless you give up.
looking forward to your response, regards Bernd
good, please keep me updated, regards Bernd
My name is Dave and I will try and help you with this one. The way the BMW security system works is it generates a "random" code and uses it to run and secure the system. What it does with this code is the neat part. Upon engine start attempt, the security module(EWS) reads the code from the key, The security module then sends the code to the DME and at that point, the DME will allow the car to start. At this point, the DME sends a new "random" code to the security module which then sends the new code to the key, allowing the process to happen again at the next start-up.
Sometimes the codes loose sync between the security module and the DME. This also happens if you swap to a new DME when you swap your engine. This can be remedied with a BMW scan tool by running a re-sync procedure, its usually called "DME Alignment/Syncing". I would start with that to solve your issue.
tried that. I had the unit at a BMW dealer service and found a helpful man there. Problem was that "... the communication with The DDE (DME for diesel by Bosch) was not possible."
Or as the service guy said: the DDE would not talk to him. Reason for that is not clear. So no re-sync procedure was possible. Any idea how to solve that?
hi again Dave. no I do not have that available. The likeliness of such failure is not high as the unit is from a new car, done 50km. And this is from Bosch, as far as I know not bad quality.
However, we will check the unit for such faults as far as visible. Do you have any idea what else could lead to such fault?
hi, reason is that the engine shall be installed in a boat. The car was written off on its first 50km by rolling it. It is now about 1 year off the road, but I have had it after about 3 months back under power and repeatedly powered it up since then. You reckon the built in memory back up failed?
hi, as stated earlier what I want is a wiring diagram, in order to find the possible fault. I will check additionally any possible power failure but would appreciate if you could find the diagram in the meantime.
hi, have been talking to the BMW dealer to get the minimum Voltage needed by the EDC. But they stated that this is not my fault. Reason: it would be identified by their system, and it was not.
So I am back with my problem: engine won't start. Communication with EDC is not possible for unknown reason, but the onboard diagnose system BMW does not identify the cause!
please respond asap, regards
hi Mike,I do not understand why the original question to the system is now hidden, it was my first request...here it is copied:"I need a complete wiring diagram for a (BMW) Mini One D , Motor N47N R56LCI Bj.11/ 2011 1598ccm 66KW VIN : WMWSW 11020 T177818"
I tried on your link provided but I do not have a wiring diagram yet. What I receives was a silly membership in a "crankplay". But still I could not access the wiring diagram that was offered by their web page earlier. A general description of the function as available by BMW directly was all I got.
However back to the fault: please read my edited response to your last answer: "hi, have been talking to the BMW dealer to get the minimum Voltage needed by the EDC. But they stated that this is not my fault. Reason: it would be identified by their system, and it was not"
But I would be happy to measure myself the voltage in the EDC to check it out. But for that I would need accurate minimum voltage parameters. Can you give that to me? Or tell me how to find out that the voltage is too low?
appreciating your accurate answer, regards Bernd
Hello again..Im sorry - I dont know why your question was part hidden... I assume thats why you have left me a negative rating - but Im afraid I have no control over that myself. Plus, because you did that - it caused this delay now - I have just happened across your question again now - your giving me the neg rating closed it to me. You clicked on OK rating for an expert that didn't give you any help at all !Im not sure now then in view of that rating whether you still want my help or not.Ive tried to be helpful to you and would be happy to be but Im not sure what you want with that now.Best Rgds, MIKE.

hi, that is a start. But as stated earlier I have a diesel. Here again:
Mini One D Motor N47N R56LCI Bj.11/ 2011 1598ccm 66KW
VIN : WMWSW 11020 T177818. And a complete wiring diagram for this would be what we need in order to find the reason for engine not starting. When the unit is connected to a onboard diagnose system from BMW it won't communicate with the Bosch EDC 17. Reason unknown, matbe related to theft control.
all sensors and stuff I considered relevant. Through the BMW system discription I had learned that the steering column lock is important as well so that is now installed as well.
Installed : engine complete with all equipment like exhaust with lambda sensor, particle filter, air mass sensor , original fuel pump and filter, original start button with key, dpeedometer and rev counter and radio, and original wiring loom. Bosch EDC, CAS, original ABS controller.
Not installed: gearbox. Brakes, small shit like lights etc.
Hope that helps, regards Bernd
sorry for the delay in my answer. I am still keen as nothing solved so far and I have put too much into it to stop here.
Send to the board if that helps. I would ask the Pope if he had a glue but I reckon he does not.
Yes, it will be a hard one but I had reasons to choose that engine. And yes, I want to use later on an additional computer to reproduce the original messages from all components.
But it should be starting!!! Before it starts I can't read out other signals. ABS computer connected. But should start without by my knowledge. What is the "Neutral safety switch"?
I hope that it does not cause confusion that I asked for a refund. But I am happy to pay my fee if there is a result, just have to make sure nothing expires here...
Have a nice day, thanks for your help, Bernd
thanks for accepting my humor. The neutral: this car is not monitoring neutral. It is monitoring the clutch. And the original clutch sensor is installed. But I do not remember how we made sure that it feels like "clutch pressed". Will check that.
Cooling no problem. For now the engine is installed in a test bench, with car cooler and all goodies.
If you had an email I could mail some pics.
However, do not forget that for whatever reason the communication with Bosch EDC seems to be impossible. No mains power on it and no communication with diagnose tool. All wiring checked, no fault. And remember all that crap is new. No rusty connectors here.
Have a nice evening or day, regards Bernd
great, looking forward to that. My wife's father dies some weeks ago which is the reason for her being with her family at this moment. And I am searching for the stuff in the kitchen.
Have a nice day,
