Cold Start Valve, URO - E12 E28 E24 E23 (M30)

Sometimes referred to as the 7th injector, this cold start valve provides additional fuel to the intake manifold during engine start and warm-up. A failed cold start valve can result in a rich running condition, as unwanted fuel leaks past the injection valve.
