Engine makes a weird noise when cold
i have a '95 e320. When my car is cold or sitting for a while(overnight) and I start in the morning, it makes a weird belt type of noise for about 15 seconds, then slowly goes away. If you start the car and pop the hood to listen where it comes from, it's one of those weird noises where it seems to come from everywhere. Drive belt has been replaced recently, so it wasn't it.
Any clues where or what could cause this weird noise? It sounds almost like a grinding sound, it's totally bizarre. I just wanted to know if anyone would have even the foggiest clue before I take to the dealership.
