Hello. I have an issue with my car and I feel that this forum is my only hope right now
I have 2016 Rolls Royce Wraith N74 engine. Similar to F series BMW 760Li
Long story short I received car with wrong DME's installed from 2011 Rolls Royce Ghost.
I found two donor DME from same year 2016 rolls wraith salvage car.
I sent both DMEs, and my original CAS4 & Key to Precision ECU and he simply changed ISN & VIN in both DME's
When I receive back and installed in the car I have permanent fault in DME2 Slave "1B2008 EWS Immobilizer protection against tampering response implausible"
DME1 (Master) has no faults. CAS has no faults. EGS has no faults. And engine starts and car will drive but only is firing on one bank cyl 1-6. cyl 7-12 are NOT running due to EWS immobilizer issue.
I swap slave dme to master and it works fine as master.. only as slave it has immo fault. doesn't matter which dme is on slave. Master side is ok slave side is not ok.
I send both back to precision thinking maybe he made a mistake on the ISN or something. He checked all and everything is matching checksum and all identical in both DME.
I install again in car. I reset all adaptation and learned values but problem still DME2 fault.
I used ISTA software to program and encode CAS and both DME but problem still there.
What can I try to do to solve this issue? Any help will be greatly appreciated and I will pay for a working solution.
Thank you and best regards my friends.
