I saw some thread here describing brake accumulators in E9s when doing 3.5L conversions, for example. My E24 has a brake accumulator and sensors connected to the brake instrument light to warn of low pressure. The warning light was flickering yesterday when using the brake. Trying to diagnose a bad accumulator I pumped the brake with the engine off for 30 times. The test passed and surprisingly the warning flicker is gone. Is it possible the brake workout really fixed whatever was wrong?
