Volkswagen Golf V Plus - ABS/ESP warning light illuminates | HELLA
Volkswagen
Model: Golf V Plus
Engine code: BLF
Model year: 2005 – 2009
ABS/ESP warning light illuminates
Error code: 1435
Brake pressure sensor 1G201
If the above error is discovered together with an illuminated ABS warning light, this may be due to the brake fluid pressure sensor.
The pressure sensor records the brake pressure in the hydraulic system and relays the value to the control unit. A signal evaluation error results in an error being entered in the control unit. As it is not possible to take measurements on the sensor itself, first of all check the parameters in this case. The setpoint should be 0 bar when the brake is not applied.
The sensor must be replaced in the event of deviating values (figure).
Repair note
The pressure sensor is integrated in the ABS hydraulic unit.
The vehicle manufacturer offers a repair kit for the ABS hydraulic unit.
Note
This information can also be applied to other models with identical ABS systems.
