30BA / 30BB DME Faults?
Upgrade your N54 BMW from MSD80 to MSD81 instead of repairing failed injector-driver MOSFETs.
30BA – DME internal fault / injector driver circuit failure, cylinders 1–3
30BB – DME internal fault / injector driver circuit failure, cylinders 4–6
Why Upgrade to MSD81?
MSD81 does not suffer from the common MOSFET failures found in MSD80
Your replacement DME is cloned and programmed to your vehicle
Plug-and-play after programming
VIN is programmed to match your vehicle in MHD, allowing you to keep using your existing MHD license
No CAS or key required
Hundreds sold
Tuned Vehicles
MHD OTS maps can still be used on MSD81. Custom MSD80 tunes do not transfer directly and will need to be adjusted by your tuner for MSD81. Your tuner may charge an additional fee for this adjustment.
