Is it normal if the SMG pump turn's on every 2 min with the engine on ? If i don't press the brake and have it in neutral i don't belive it turn's on...at least that often. But if i have it in gear i can constantly hear the pump ... max break period 2-3 min after it turns on again. Also when i open the car the pump sounds like running to much don't know the time exactly somewere like 10 sec. Smg works ok ... Is this normal ? Thanks.
