  • EGR valve: The EGR valve has the advantage that it is often easy to access and simple to disassemble/clean. You can always examine it and clean it, for this see our article content on cleaning the EGR valve of an Mercedes Viano.
  • Injectors: Injectors are very delicate parts and a few impurities may be enough to bother 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 simply have to replace it with a new one.
