The 2.0L Turbo (2.0T TSI) engine was first introduced half way through 2008. It was no longer used after 2014. It was primarily used in Volkswagen and Audi. The 2.0T TSI was a fairly reliable engine, but it does have a list of common problems. This article will outline the common VW engine problems and how to detect them.
Fuel Injectors
This engine uses direct injection to spray the fuel into the engine’s cylinders. The fuel injectors the piece that sprays the fuel. They are subjected to high levels of heat and a large amount of pressure. When they fail, it can cause VW engine problems. The injectors either stay open and spray too much fuel, or they stay closed and spray no fuel. A sign of a bad fuel injector is the cylinder misfires. You may also notice a loss of acceleration and power. In addition, you may see gas dripping from your engine. You may also receive an engine misfire code or icon on your dash.
Water Pump
A water pump pushes water through the engine and radiator. The pump is housed in plastic and subjected to a high amount of pressure and heat. As you can imagine, the plastic housing does not hold up well. This often leads to a leaky water pump. When your water pump is leaking, the signs that indicate it include a low engine coolant light. Your engine may overheat, and you may see coolant leaking from your car on the ground.
Ignition Coils
When the engine misfires, it is often caused by a missing spark. When there is no spark, there is no combustion, and the cylinder cannot create power. This can also cause there to be a build up of fuel, which ignites from the heat and causes it to be out of synch with the rest of the cylinder. The ignition coil is what sends electricity to the spark plugs. When the ignition coil is bad, there is no electricity to send. Some ways to determine if you have a bad ignition coil, you may experience rough idling, engine misfires, and a loss of power or acceleration.
PCV Valve
The positive crankcase ventilation (PCV) is what captures the gas created by the engine and circulates it back through the intake system. The valve is critical in reducing emissions and capturing fumes and unburned gas. If the valve is not working, it does not capture the unburned gas. A faulty PCV Valve may cause performance issues with your car. Signs of a faulty PCV Valve are rough idling, intake noises, and misfire fault codes.
