I cloned the DME, thats all

how ?


I started this thread so I will explain what was done in the troubled car.
Because I don't have access to tools like "Ecu Explorer" so I decided to use help from BMW Partner. They copied ISN from car's DME to DME of the engine that was installed in the car.

I have some problem with reading preconditions of the engine, especially temperature. I need to check engine wiring. BMW Partner discovered the VIN number of engine donor. The engine is N55 (like original engine), but this one is from BMW M135. More power but need to check if there are differences in wiring between 335xi 2013 and M135xi 2013. Maybe this is the issue with temperature readings.

Hi.
I have this error in my car:
1F2108 DME, incorrect data record: Variant monitoring

What is this variant monitoring?

It is fault related to power class coding which DME checks with CAS/FEM/BDC(depends on car type).
For example, basic DME is used on few types of cars from 2.0 till 2.8 with N20 engine,but firmware is different. You can change firmware while DME is particulary new or till 10 operating hours.
You are probably trying to use M135 DME on 335i car.
