How to Repair the High-Pressure Pump on an Audi Q3

Model: Audi Q3 8U - Years 2011-2018
Part: Pump

In this video tutorial, you can see how to repair the high-pressure pump on an Audi Q3. The first thing to do is lift the hood and secure it with the prop rod. Next, remove the cover; inside the timing cover, check the timing belt. If the belt is in good condition, check the sensor that manages the pressure of the high-pressure pump. Look for any metal shavings inside. Once you identify the problem, you need to remove the timing belt to access the high-pressure pump. Then, remove the high-pressure pump, open it, and replace all four injectors because any debris in the nozzle and atomizer creates damage. After that, replace the low-pressure pump inside the tank, and also replace the fuel filter, cleaning all the lines, both rigid and flexible.
