Engine still running fine, over 1 year now.
I now have some random not starting problems. I've replaced the batteries in the keys. INPA and iDiag sometime show DME and EWS not in synch: "EWS preventing manipulation". If I leave the car for a few minutes or hours it starts fine.
I'm considering replacing all units: DME, EWS, keys + ignition lock from another E53 N62 car.
Any other ideas?
