BMW intake acid cleaning at home-simple and cheap-N47, N57 diesel engines

Because of the EGR system, everything is soothed and full of sludge from intake manifold to valves, after years engine will loose performance and become sluggish due to a blocked intake system and it will cause many other issues include more contaminated engine oil running in the engine through all tiny passages, includes timing chain areas and tensioners and by cleaning it the intake system, this should help to bring the car back to life and also prolong engine life. EGR will be turned off by me via software and by blanking in the next video to avoid all issues above to ever come back.
Cleaned intake manifold, shudder valve, map sensor, intercooler and the pipes, replaced gaskets, intake breather pipe and also breather valve, all done due to a preparation for decat, egr off and remap which will be shown in the next video, remap and all works will be done by me at home without need for expensive equipment.
