F31 DSC control unit

MrBlueSkies · 06-21-2023, 09:25 PM

A bit of a long shot but here goes. I have a 48070D code on my F31. Traction control is not working. The message is "DSC unit: Valve data for intake valve, EEPROM, perform adjustment"
Code appeared after battery got low. Have now replaced the battery, but cant shift the code. My Foxwell has a DSC valve calibration routine which I have tried a few times, but which always fails.

Before I go down the route of finding a replacement DSC controller (1300 Euros for a new part!), has anyone else had this problem and solved it? I'm inclined to believe it's just as likely to be a software issue as faulty hardware, but cant be sure. Would getting it on an ISTA be a useful next step?

Thanks for any input.
