DDE7 811 111 EWS4 SYNC ISSUE - DESPERATE TO RESOLVE
HI Guys
if there are any BMW genius's out there, please can you help me with the issue i am having as i have been trying for 3 months with no solution. BMW x3 (e83) - n47d20a engine automatic 2009 ecu: DDE7 811 111 ews Version: 4.4 Vehicle was driving and running perfect. Came in for brake and suspension repairs. Car drove perfect after repairs. Parked it over the weekend and battery discharged. we tried starting it and it cranked once slowly but didnt start. After replacing battery it didnt start. Fault code is 2E41 - DDE/EWS interface. I tried loading eeprom on another ecu to see if the original ecu was damaged but no luck. With new ecu , i cannot even do diagnostic via obd. It says no communication. but the ecu is definately working. ORiginal ecu reads via obd but code will not erase. No ews/dde synchronisation is possible as this is EWS4 and doesnt allow synch. Any advice or suggestions will be greatly appreciated. I am desperate. Customer is making me pay for a hired vehicle. |
