Before

I’ve decided to do this just as a precaution and without any symptoms. Anyway, I was stunned by the results. First, everything was much clogged than I suspected and second the calt felt much better – engine work became more quite, the car became more powerful especially on lower speeds. Highly recommended procedure for all of you diesel car owners out there!

    Awesome, I was already wondering whether to do it or not after having the EGR disabled, absolutely seems worth it!

      How did you do it by the way? What cleaner and equipment did you use?

    I used ultrasonic clelaner for this procedure and degreaser mixed with water. 30 minutes “boiling” in it and it’s brand new.
