Help! I have a b37 116d 2015. I noticed a noise in the engine bay, had a look under the bonnet to find the radiator hose hitting the serpentine belt. Causing the belt the fray and split. I then noticed allot of oil covering the pulleys and surrounding areas. Does anyone know of what could cause this leak? It’s currently in the garage but I just want to know what I could be up against before I get absolutely rinsed.
