SPN 102 FMI 18 CM2350

[W9L]

Had that exact code and a leaking type noise a couple of months ago on a 2014 isx15 cm2350. It was the hose between air compressor and intake manifold. It is a rubber hose about 1" id that connects to a tube with a large nut connecting it to manifold. Had to order it as no one had in stock locally. In the meantime I used a 90 elbow and some 1 inch heater or radiator hose and hose clamps.
