Hope someone can help with this, 2012 S350 bluetec, the electric circulation pump is noisy I can hear it inside the car when idling and when the engine is off with stop/start, it is located near the battery on the bulkhead so it can be heard inside the car, my question is do I really need it as it's main function is to circulate coolant when the engine is off and you press the rest button, can I just unplug it or will this throw up a fault on the dash?
