Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
The lateral acceleration sensor can be a common sensor to fail and requires replacement when it does fail.In almost all cases when this code sets for this sensor the sensor does need replaced.This will turn on the traction light like this here and in some cases may turn on the tire light.Usually though the tire light will only come on if there is a low tire or to high of air pressure in a tire compared to the rest or if there is a tire pressure sensor fault.
I would have the tire pressure sensors checked/tested to see if any of them need replaced.Usually a local tire shop can check these with their tool and most will check them free of charge to see if one needs replaced.
I suspect worse case scenario here the lateral acceleration sensor needs replaced and a tire pressure sensor then the fault codes cleared and tire pressures relearned to turn off all the lights/messages on the dash.

My info tells me this sensor is part of the DSC sensor cluster https://www.dropbox.com/s/804whhjb3l8uspp/dsc-01-20.gif?dl=0
This looks to be between the two front seats under the console area.

Did you see any wiring issues leading to or at the sensor including the electrical connection to it?
Have you had the code cleared with a compatible scan tool and was the vehicle driven around 20 miles or so to see if the code clears out then at all?It sounds like the sensor is not working again so the code should clear but some models require some driving to clear it out.I am unable to locate any test procedure for this sensor here or if it needs calibrated on this model but I know some of these sensors after replacement needed calibrated with a dealers computer plugged into your vehicle.I would see if driving it clears out the fault here.
I do see that some do need calibrated.It is a function using a factory scan tool/computer plugged into your vehicle to calibrate it.Some of the after market scan tools like the Solus o Solus Pro may not have this option to do this calibration.You may have to have this checked and calibrated using a scan tool or computer that can do this by a BMW repair facility or European repair facility.
