SMG Codes. New Battery. Wont Start
2006 E60 M5, with 64K Mi.
Was getting intermittent red and yellow cogs before car finally just won't start. Also its stuck in first gear.
Battery was changed and registered and has been kept on charger. When i unlock the car, voltage drops in half. did the same on previous battery.
Codes I'm getting:
4F40: SMG: Hydraulic unit, Undershooting of pressure range
4F42 : SMG Hyd ctrl unit; activation frequency, pressure build up
4F43: SMG Hyd unit: ON period
5211: SMG: signal, key number, is faulty (CAS)
A46D: CID: CID malfunction due to peripheral
9D12: SINE: internal battery
I'm assuming this is the SMG Pump Motor as I no longer hear the whine when unlock/open door, but could it be something electrical that i'm overlooking? Any idea what the last 2 codes are?
