Hi Guys,

New to the forum. was hoping i could get some of the experienced guys to help me with a situation i have at my workshop,.

2007 Bmw x3 2.0d - n47d20 engine
ecu: dde7 811 111
ews 4ool.
the vehicle's battery died over the weekend. We didnt know this and tried starting it to move it out the workshop on monday morning. Car would swing but not start. After replacing teh battery, we tried again. WOnt start.

DDE - EWS Interface error.

apparently this version of EWS cannot be resynched as it has a rolling code / ISN which is now mismatched due to us starting it with a low battery.

I tried many diagnostic machines and none of them allow EWS/ DDE sync. They all state this version doesnt need calibration.

I have also tried the spare keys.

Can anyone point me in the right direction to get this car started. IS their a way to sync the ews and DDE?

I have had a similair issue before on many BMWs but was always able to resync using diag tool. 


Any help will be appreciated as i have had many locksmiths etc try with no joy and customer has now hired a loan vehicle which i have to pay for until i get his car fixed. PLS help.

Any info will be appreciated.
God Bless
