glow plugs

Hi everyone, friends. I just got out of service. as a passive fault that one of the glow plugs in the brain was broken as a car breakdown. do I have a loss of performance or loss of performance in this car, this is only after working to start the car, it did not have a task but the brain may contract itself because there is a malfunction, I am waiting for your comments, thanks

BSI There is no such thing as self-contraction, the glow plugs are used to heat the diesel for the first start in cold weather and are only found in diesel vehicles. It is a necessary and useful invention. Replace the defective glow plug in case of future problems with your vehicle.
