In reply to Oliver Hughes. 100% agree! Thats exactly what these manufactures want us to do is feel incompetent and rely on their dealer mechanics to overcharge us for things we should know about our own vehicles. I have a '01 Audi Quattro A6T 2.7 and since buying this POS 3yrs ago have learned so much about fixing them its absurd! everything from replacing the front main seal, timing belt/tensioner, water pump, thermostat, (mechanics were turning me away or wanting thousands to perform these tasks!) replaces many sensors, fuel pump, front and rear brake pads & rotors, etc. I am by no means a certified mechanic. but was able to perform all these tasks myself and saved me THOUSANDS of dollars! Get your hands dirty folks! its satisfying to overcome these challenges...

In reply to Henry Macsa. I would call that a symptom, not a cause. Since you've noticed increased fuel consumption, I would check the ignition system first (coils, plugs, etc).

This p0300 code always comes in my audi a3 sportpack 2007 model car, i several times troubleshooting it and always checking possible causes and tried to fix but no. When i read your article about it , i saw that one of the cause is “Increase in fuel consumption” i didnt check it previously, thats why maybe im encountering this p code.

In reply to Tommy. I don't know, they could be unrelated. My advice is to pay the diagnostic fee to have a technician take a look at the vehicle in person.

An informative article. People who drive cars should be aware of these things and not just stay dependent on car mechanics. This is the key to survival in bad situations. Also, it is not guaranteed that the mechanic knows it all. Better to take the well-being of your car in your own hands.
