Factors that makes your Audi A3 graze


The first thing to do as a diagnosis on your Audi A3 is to clean the various parts. Actually, dirty parts can trigger acceleration problems. So check your filters, as air and fuel go through this path before attaining the injectors. If the road was blocked, think of it as a blocked highway, everything is slowed down. Clean them, and if they are too old, it is realistic to change them.

Injectors of your Audi A3:

Directly related to these filters, the injectors obtain the fuel through the filters, and then supply the combustion chamber, where the spark plugs ignite the fuel, which enables your Audi A3 to move forward thanks to this process. If you had poor quality fuel or simply fouling at this level, the pressure of the injection pump could be damaged, and therefore combustion would no longer be accurate. Of course, this will be felt in the acceleration of your Audi A3.


As mentioned above, the spark plugs fire up the fuel once it reaches the combustion chamber. If it hasn’t had any problems up to now, maybe that’s where it comes from. If the spark plugs are faulty and have problems igniting the fuel, you will have trouble driving gently with your Audi A3. Check them and change them if necessary.

Hoses of your Audi A3:

In your Audi A3, you have small hoses that are identical to small pipes that also enable the transport of different fluids. They need to absolutely remain waterproof, otherwise you will also find yourself grazing because the fuel or oxygen supply will not be heterogeneous.


Another point to check if the Audi A3 grazes is the calculator. This one is responsible for the ignition but also for the injection. It sends orders electronically to ensure that this task is done. Imagine a conductor giving inconsistent instructions to the orchestra, it would end into a rather chaotic situation. The same is true for your Audi A3, which would end up grazing. If the calculator is involved , it becomes more difficult to manage yourself. It is more reasonable to go to a garage to have it recalibrated or replaced if it is not repairable.

Conclusion :

Here are the main motives that could cause your Audi A3 to graze. It is important to note that it is often dirty and generally poorly taken care of parts that will cause this. Try to regularly monitor the inside of your Audi A3 by cleaning what you can.
