Hi again. Still at it. Starting to give up tbh. Anyone know if I can measure voltage at the brake pressure sensor plug. If there is power coming through?
I've replaced the brake pressure sensor(with used OEM), then I also tested a new Bosch sensor but just plugging the connector in and checking the pressure. Still stuck at 290bar(doesn't matter if I press the brake pedal or not) and the same fault code(01435-electrical fault in circuit). Have replaced the brake light switch. I unwrapped the wiring from the ABS module connector to the wheel well area and everything looks okay. I've checked resistance between the 3 pins at the pressure sensor and the ABS module connector.
I feel like the only thing left to do is replacing the module with a known working one. I've had it repaired by a friend.
It's the only ABS related code left and both the yellow ABS and ESP light comes on when that code appears.
