Hello guys My brother has an Opel Omega 2L 16V Built.96. For a short time the funny thing is going on. Example: the engine is running in the stationary gas and the light is switched on, but as soon as you start the light becomes dark for a fraction of a second. That happens every time when you start the car. The engine and the rest of the car are actually running very well. Has someone ever had such a thing or can give me a tip what that could be ? mfG Armin
