Help me please, i have a problem whith DSC module. Error 48070D, Valve has not been calibrated.
BMW I3 REX 2015, 90000 Miles
I tried to do the calibration but it doesn't work. There is no air in the brake system, I checked.
Hi . I'm Daniel,
I'll be the mechanic assisting you today.
Let's see if we can figure this out and get you back on the road quickly.
Here is the fault code description:
48070B DSC control unit: General valve data, EEPROM, perform adjustment
Fault Code Description
Valves calibration data missing or incorrect.
The fault is also stored if the control unit has been renewed.
Perform following service function:
DSC control unit adjustment
The fault is also logged when the control unit's internal EPROM is defective.
As a first step, try to re-learn the DSC vavle calibration with a capable scanner. You should find this under "service functions" or "activations".
If the function fails or does not clear the code we are most likely looking at a failed DSC unit that needs replacement.
What we can try as well before replacing it is to re-flash the DSC unit to the latest software and check if this changes anything.
I'm sorry that you have to deal with this, I know it can be frustrating.
Let me know how it goes and if I can provide anything else at this point.
