  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will release the wrong amount of mixture and thus prevent your engine block from working properly, it is even possible that one or more of your cylinders are not running effectively.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass effectively and therefore bother the operation of your Audi A2, up to the point of leading to vibrations during acceleration.

So make sure check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Audi A2 to your garage.
  • EGR valve: The EGR valve has the benefit that it is generally easy to access and simple to take apart/clean. You can always examine it and clean it, for this see our article on cleaning the EGR valve of an Audi A2.
  • Injectors: Injectors are very delicate auto parts and a few harmful particles may be enough to bother their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a expert.
  • Fuel Filter: If it is the fuel filter, simply change it. A fuel filter doesn’t clean itself, so if it is clogged you will just have to replace it with a new one.
