^ What he said.

Can you post your original ZCS strings and your modified one? Also, when writing the new ZCS, don't do the whole truck. Only the modules which store the ZCS. For the E53 I think that's the EWS and KOMBI (cluster). After you successfully code those two, the EHCII module should disappear.

Then, since you have a 4.8 you will have to code the DSC to think it's in a 4.4i N62 using NCSdummy or you will have a dsc error and light on the dash.
