P2181 Cooling System Performance DTC. So I took the coolant temperature sensor off and found it has so much residue around its copper head.Your Passat’s engine needs air, fuel, and spark to achieve optimum ignition . When one or more of these variables is off, it can lead to a rough idling condition. Fuel – The ideal air-to-fuel ratio is 14.7 parts air to one part fuel. Air – The air entering your car’s engine must be metered by the MAF or MAP sensor.
Check Engine Light Warning The dreaded check engine light can mean a lot of things for your Volkswagen Passat and can range from a simple fix to a major expense. The symbol may appear as either an icon with text in the middle or may appear without any text and be the outline of a sort of transmission.
Reduced Fuel Efficiency. When your Volkswagen Passat’s oxygen sensor (s) are not working correctly, it can disrupt the optimal 14.7:1 air-fuel mixture, which can negatively impact your gas mileage. Since the oxygen sensor plays a key role in maintaining the efficiency of the combustion process, a bad sensor can result in poor fuel economy.
