just to update, i have left the battery disconnected. tomorow i will re connect, boost the battery with jumper cables to get good voltage above 13.7, then try again to re code the dme/ews.
only fault code is d1(hex) = 209(dec) = immobilizer controll module - incorrect signal.
I have also found tis PDF guide to ews. Seems very usefull.
p.s i am tempted to get another ews module of auction/breakers. however just to confirm this WILL NOT WORK because the ews MUST be coded to the car VIN as from factory? and there is no way to re code used ews modules?
