Good day. This is a 2015 F30 with B48 enjin DME MG1CS003
The original problem started when the owner of this car wanted me to change all the vin nr's in all the control units. This car was running 100 persent, no problems. The car and all the control units had the same Vin nr. It is a rebuild. There was no papers for the original car. So customer changed the vin on the body and door ext. To a car that was still on the road. I started by changing the vin nr on FEM. All ok. Car was still starting. Then I coded cluster. Car was still starting, cluster was ok, New vin on the cluster, no problem, Then I wanted to change the vin in the DME, so I used Autohex to program this DME, There was no coding avalable, only programming. So I did programming. It failed programming. After that. The car did not crank, So I updated all the ECU's. Only Ecu that did not want to update was DME, So I changed vin Back to original. After that ,Still no cranking. So I thought maybe fault in FEM and DME. Made a stuped mistake. Took original key. Blanked it. Made it again. Now car switches on, but no Smart acces or remote.
After that I bought brand new key . BMW key, code new key, All ok again. Key work 100 persent. So I found someone to help me with Esys. He charged me $300 to get the DME alive again. So now the car is cranking again, But DME fails ews tampering, He said problem in FEM. But FEM has no fault codes at this stage. So I bought original ICOM A2 Next head, Bought latest ISTA-D , program car with ISTA-D. It did not want to do any programming untill DME was programmed, But it kept on failing DME programming. Now car is Not cranking again. DME is now Bricked. Keeps on comming up in blue on ISTA-D. If I use E-SYS to check There is no Coding file in DME.
Thanks
