Just been out in my E36 M3 saloon and the check light started flashing on the dashboard and the check control said 'Brake light circuit'. I checked the brake lights and both are working! I switched the ignition off then restarted the car and the check light went out,started driving and as soon as i touched the brake pedal the check light came on again. What does this mean ? |

Check the watage of the bulb also, if one is wrong it will also cause check light to come on.

Mine used to do this all of the time. It turned out to be a faullty brake pedal switch so probabl;y worth checking that.

The reason I ask is that very infreqently my brake light warning on the check control crys wolf from time to time. I have always put it down to the third high level light that was fitted to it when I bought it. ------------- Kevin '04 E46 330Ci Convertible '08 E61 535d Touring (TorqueMeister Towbarge) ’95 E34 M5 ’89 E30 M3 (Cecotto) |

that may be the case with yours but it didnt work with mine , which is why i disconnected it , once the check controll unit is disconnected it will also stop all the other warning lights ,buzzers , sirens , strobes machine guns and laser guided misiles from going off in the car aswell . ------------- e30 2.7 cab e30 325i e30 325 sport e30 318 touring e28 m5 e28 m535 e34 m5 e39 540 e36 318ti (green) e36 318ti (mauve) |
