Hello,

Thanks for posting the vehicle's Auto-Scan! By the way, the VIN says this is a 2017 WAUZZZF44HA040130 [H = 2017]
Date of production: 21.07.2016
Model year: 2017

I would suggest to have a look at the Advanced Measuring Values in the J104-ABS Controller for the [Pressure in brake booster] and see what it is reading.

With the engine idling, the G608-Vacuum Sensor should be around [-800 to -950mbar] providing there is a decent amount of vacuum at the brake booster.
- The value should change when the pressure (positive or negative) changes.

If not, check the wiring, connections for any concerns, including but not limited to coolant migration and or corrosion.

Hope this helps,

drpeter

turns out its a flaw in the abs software that does not allow this fault to clear after it has been seen too many times. apparently the only way to fix it is to fit a new module.

Did you fit a new module and fix the car or was it done under waranty?
