My GTI VR6 check engine coolant light went off last night. So I stopped the car at a gas station nearby to add coolant to the engine because the car was overheating and smoking. After adding the coolant, I tried to start my car but the battery died. Also the coolant was leaking out the bottom. So I had to tow my car. After replacing the battery, my engine would not start. Anybody know what could be wrong? I do not want to take it to a mechanic quite yet because it will cost me an arm and a leg for them to take apart the engine to see whats wrong with it. Please Help!!!!
