Hello All, I am new to the forum. I am planning on chaning my serp belt, tensioner pulley and the upper idler pulley. Is it best to use OEM parts? Will parts from Advance or another parts store suffice?

Thanks in advance, Jake

I did,belts are belts.As long as you get gates or better.

Jake, why would you need to replace pulleys on a 2005 MB automobile? Pulleys aren't wear items, and they should last for decades and several hundred thousand miles ... the life of the automobile.

Ferdman, I am getting some whining from my tensioner pulley and if I am replacing this I thought I may as well do the idler.

"May as well do it" is a scam more suited to 'merikun iron. Certainly not the way Mercedes are designed and most often maintained.
