Audi TT Car is stalling Inspection at your home or office.

Common reasons for this to happen:

Fuel Filter

Fuel filters get clogged over time and most vehicles require replacement at regular intervals. In the case of a bad fuel filter, you may find that the engine seems to lose power when going up steep hills. Your vehicle may also have trouble starting up from time to time. In extreme cases, the engine may suddenly stall when waiting at a stop light or even accelerate poorly on the open road.

Fuel Pump

Just as your fuel filter can get clogged and dirty, so can your fuel pump. However while the filter simply serves as a strainer of sorts to remove the contaminants in your fuel system, the fuel pump requires both energy and fuel in order to operate properly. Fuel pumps can stop operating due to a blown fuse, moisture in the fuel system, or even the motor within the pump wearing out over time. As with anything else containing moving parts, the fuel pump needs lubrication. That lubrication comes from the gasoline it pumps. If you tend to run your tank extremely low or empty, your pump is literally running dry which may lead to premature failure.

Vacuum Leaks

Hoses in cars are like veins and arteries in your body. The vacuum hoses primarily function as the sinuses for your powertrain. Your car needs a precise air and fuel mixture in order for fuel to be converted into rotary energy. When you have a vacuum leak, it means that one or many of the hoses that guide air into your car’s system is leaking. More often than not, a vacuum leak will be associated with a high pitch hissing sound from under the hood. If the source of the leak isn’t readily visible, a technician may need to perform further inspection.

Sensors

Modern cars now require a variety of sensors in order to keep all the energy, air, and fuel flowing to the right parts of your car. Sometimes a sensor’s connector may become loose over time and may just need to be snapped back on. Other times, a sensor may need to be replaced. If your Check Engine light has come on due to stalling issues, a malfunctioning sensor may be causing the car to stall. One Check Engine light may be caused by literally hundreds of individual faults. It is important to understand that the trouble codes displayed are only a guide to finding a solution, not the solution themselves. Use caution when having codes "read” at a parts store or auto repair shop and basing diagnosis only off that information. Codes are but one tool in the toolbox to decide which sensor may be defective.
