So remember to examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Mercedes A class to your workshop.
  • EGR valve: The EGR valve has the advantage that it is often times easy to access and simple to take apart/clean. You can always examine it and clean it, for this see our guideline on cleaning the EGR valve of an Mercedes A class.
  • Injectors: Injectors are very fragile components and a few impurities may be enough to affect their performance. 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, just 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.
