Guys, Today my brother's 97, 318i suddenly just slow down while halfway running in highway as the pedal seems to be malfunction, no pressure at all and the car just stop. And after that, he turned off the engine and try to restart, the car wouldnt start anymore. Car is towed back to workshop and gotta wait till tmr morning to rectify the problem. This is the first time the car break down halfway without any hint or signs, it has been running flawlessly all this years. Any idea what causes it? Gearbox? Fuel pump? Appreciate ur help. Thanks in advance. Regards
