Audi A3 is one of the very few luxury hatchbacks in the market today. It stands between a regular hatchback and an expensive luxury wagon, making the model provide a distinct flavor quite a number of buyers are looking for. However, if one is looking at buying a brand new or a second hand Audi A3, there are things that should be noted. The Audi A3, much like any other models, is prone to some problems that need to be addressed to regularly. Following are some of these issues to help owners maintain their A3's more efficiently.
Most Audi A3 parts that faced a lot of issues in the past involved the power train. This includes the temperature sensor wiring harness. This particular part is connected to the temperature sensor found at the direct shift gearbox or DSG. The connector wires in the harness should be crimped at a particular level. If not, as is the case in the past issues, the temperature sensor may detect false high temperature in the DSG. This automatically makes the gear shift to neutral, giving less control to the driver.
In 2009, there had been a recall for this particular issue wherein 16,000 units were estimated to be affected. Volkswagen called upon affected owners to reprogram the transmission control module for free. The software on the car computer was also updated to fit the new module.
Most Audi A3 owners found coolant loss puzzling. This may cause a spike in the engine temperature that can eventually lead to some serious stalling on the road. They had their engines and radiators checked but no leaks and faults were found. This might be a problem with the heater core. The heater core is like a small radiator found under the dashboard of the vehicle. Leaks may be present in this part,
A problem with the fuel system occurs when there is an issue with the fuel injection rhythm. If the injection rhythm is not working well with the fuel injector line's own rhythm, it will cause stress to the lines. This problem will eventually lead to fuel leakage that might catch fire. When it had its recall in 2011, Volkswagen installed vibration dampers on the fuel injector lines of affected Audi A3's.
