W212 Brake warning light
Got a code from a local indie “component b64/1 (brake vacuum sensor) has electrical fault”
Purchased sensor (part no
A 007 542 03 18 which is replaced by A 000 905 48 04) - £66 from MB.
Fitting is fairly easy
Sensor is buried
Undo this bolt (17mm) and lift bracket up - I supported it on a block of wood. Access to the sensor is then a doddle - carefully lever out with a screwdriver, push in new part after plugging in 3 pin connector. Re-assemble Brake warning light extinguished 😊
