Hi everyone,

I replace a used DSC with pump into a E91(2007)
I changed the VO with tool32 and did calibration with ncs expert and ISTA D.
Everything working except cruise control.
Those are the fault code:
CDAD Message (request, wheel torque, drive train, 0xBF) faulty, receiver DME, transmitter DSC/LDM
CF1D No messages from DSC, receiver DKG/EGS, transmitter RDC/DSC
D35B No message (LDM, 0x213), receiver DSC, transmitter LDM
A8B7 FRM: Brake light, right, faulty (brake bulbs replaced by LED)

The car comes with VO $544 that means this car should not have a LDM?
Also I can't find LDM at ISTA nor NCS expert.
Did I replace a DSC that not support $544?
I've tried to change the VO to $540 but nothing changed.

The part number I removed from car: 6776068
The part number I put into the car: 6775388

Could someone help me?
Thanks
