Hello, friends. Needs some advice.
I have 2013 BMW 535xi m-package.
VIN: wbafu7c54ddu69831
Needed to replace DME because of valvetronic codes.
Got exactly the same DME as original (8 606 309 -01, Bosch # 0 261 S08 996, BMW # 170103882)
Used "Factory ISN" function and copied original ISN and working hours on a bench.
Put used DME in a car, and programmed/coded it.
Now it has a code for a radiator shutter grill. This code WAS NOT THERE BEFORE.
CD9203 Radiator shutter, LIN communication: Signal Faulty.
This car doesn't have a grill shutter option, FA Manager doesn't have this option selected ($1CB i believe), there is no grill shutter behind the bumper and no connector anywhere for it.
So I put original DME back and reprogrammed it the same way, using Autohex. No code for grill shutter! Put the used one and reprogrammed again, code came back.
I also tried ISTAD+ with the same result.
Any suggestions on how to force the used DME to delete grill shutter option?
