good morning

I would like to point out a very interesting case that happened to me:

Mini Cooper 1600 Petrol engine N12B16A year 2007

this car presented    ABS warning light and hand brake light on steady

The following errors were displayed in the diagnosis, suggesting a fault in the abs system

error 5DAE UNIT INTERNAL PRESSURE SENSOR HYDRAULICS

error 5DBB UNIT HYDRAULIC PRESSURE SENSOR PLAUSIBILITY

Finally, after several checks, we realised that there was no oil in the brake fluid reservoir.

I suggest what we did

We checked the brake oil level in the brake reservoir was below the minimum level . We added and restored the correct brake oil level in the reservoir. We solved the problem 

In addition, we also did an electrical check of the BRAKE OIL LEVEL SENSOR - BY MAKING A BOND ON THE BRAKE OIL LEVEL SENSOR.

This reset the system and the warning lights were switched off. Errors in the ABS ecu were reset / deleted .
