G'day, I have recently swapped the engine in my touring, I was running everything the same. Went from m54b30 to m54b30. Did a better swap in my key and now getting the error 128. I can't get the dme to enter boot mode, on chassis or on bench setup, presumably my pc as I get the wrong byte something on jmgarage and no hardware viable on ms4x flasher. I'm first of all curious if a ews delete will remove my error 128, and secondly curious if I can use a EWs module and key chip in this car from a wrecked car I have. And the process for that. If someone can do it remotely im happy to pay, I just need it running. It cranks but won't start.

Any advise would be greatly appreciated, E46 touring 2004 DME ms43 running 069.

Thank you so much in advance.



Edit. Managed to get a dme into boot mode, loaded fresh m54b30 firmware with VIN changed, put in car still getting error 128. And cant seem to sync dme with ews. although its eews deeleeted so i dont know the issue.
