Lot's of things can rattle or buzz
Hiya,
I would look to the foot brake linkage or maybe the exhaust pipe mounting.
When Diesel engines start, they run rough because the air does not heat as well from the compression stroke as when it's at operating temps so the fuel does not burn as well. (this is why they tend to smoke and smell like a candle) Since it's running rough, any pivoting linkage or sheet metal components can vibrate enough to make noise. (Ask your mechanic how much noise a loose converter heat shield can make on a car)
Total WAG as I haven't been there in person,
Tom
