00003 fault code

[Ca11um43]

I recently purchased a 2009 Audi A3, with a bad ABS module...It was removed and sent away for repairs, so the battery has been disconnected for over a week. The repaired ABS pump/module is now back on the car, and I had quite a few faults for the steering angle sensor, acceleration sensor, etc etc (none of these were there before). Luckily I was able to recalibrate most of them with my Autel MK808 scanner, but there is 1 which won't go, and that's "00003 - Control Module - No or incorrect basic setting/adaptation". Again, that fault was never there before, but it's causing the traction control and ABS light to stay on. I have the option to calibrate the "basic setting of inlet valves" on my scanner, which is what it said I need to do on google. But the calibration keeps failing. So what else could I try? Need it sorted quick.
