Engine Compartment Insulation, 2011 M37


New member
I opened my hood and found a big wad of white, cottony insulation tucked up over the wheel well near the fuse box. It appears that squirrels had gotten under the hood and torn off some of the quilted sound (or heat) insulation from the back of the engine compartment, near the bottom close to the driver's side wheel well to use for a nest. Nuts!

I don't think they've caused any other damage, and I've moved my car to an enclosed garage ... but can anyone tell me how critical this insulation is, and the best way to go about replacing it?
