Hello together ! Has someone already cleaned the intake tract of the diesel engine preventively from you. Is there a few relevant videos of MRI (e.g. https://www.youtube.com/watch?v=HUVp0l7v2IY). Only about two things here I am in the unclear: – Can one re-use the support seals of the plastic intake bridge, or will there be any problems with a reuse? – How is the pressure sensor to the intake unit properly cleaned ? – to the meta Illic part of the suction bridge: how far can one go in the direction of cylinder heads for cleaning and how does the cleaning by hand? If someone has already made his own experience with the Subaru diesel with regard to soot (from the AGR) and oil vapour (from the KGE) existing deposits in the intake tract, please write them here, or refer to a source where one can read this. [and no, I did not find out in detail in the search] Greetings
