A mechanic left Mercedes Benz part # A 642 016 2524 off my Sprinter engine. I found it loose in the engine compartment today, about 10 days after having a glow plug replaced. Does anyone know what it is? I would put it back on the engine if I knew where to start my disassembly...... I would guess that it is some kind of heat shielding of vinyl foam. The other number on the item is 01 12233C
