C123EF0 - Hydraulic Brake Booster Limit Value Reached
This code gets stored in the ABS unit permanently after the yellow light warning is repeated 20 times.
Options I have found to fix this code
The dealer quoted me £3000 to fix this code by replacing the ABS unit as it can't be re-programmed.
The second option is sending your ABS to Ecutesting it costs around £300.
Does anyone know if this code can be removed by re-flashing/ re-coding the unit via software such us ODIS, OBDeleven, VCDS or MPPS.
