LIQUI MOLY 400mL Pro-Line Diesel Intake System Cleaner (Aerosol) 6.1 lb

To prepare, attach tube with nozzle. To gain access, remove hose or pipe immediately before throttle housing. The engine needs to run to perform cleaning. If unable to start engine, disconnect air mass sensor connector while the ignition switch is in off position. Maintain minimum engine speed of 2000 rpm while spraying cleaner in short intervals of 2-3 seconds, and at the same time move the nozzle back and forth across opening to completely treat intake tract. If engine speed fluctuates more than 1000 rpm stop spraying immediately and wait for speed to stabilize. Keep cleaning fluid from contacting air mass meter or painted surfaces. If excess deposits inside EGR valve, intake manifold or intake valves, a second can of cleaner may be used to improve the result. After completion, leave the engine running at 2000 rpm for a minimum 20 seconds to allow complete removal of any residing fluid in intake system. Afterwards erase any stored fault codes.
