It is better to buy them by 'year make model' rather than part numbers. It is called a 'Serpentine Belt' because they no long drive the radiator cooling fan :>)

Check for loss of fluid
Or power steering pump needs to get overhauled

I don't know why they did this, But other manufacturers are going this way. The consumer can't check the transmission fluid. They have to go to a shop. You can get the stick online. Yours at operating temps are 16 to 17, or 160 to 170, depending on the stack you get. The stick is cable with a metal piece on the end. Push it down until it bottoms out. If you shove it to far/ force it. You have to remove the oil pan to get it out.

if its a chain there is none but check for noise from the guides and tensioner if you hear a grinding sound from engine or a rubbing noise then you should check the guides or tensioner for ware

VW sprinter diesel newish model ,no chance here without specialist software dealer only job

Normally problems starting could be the glow plugs these warm the diesel up making ignition easier also check the wires going to glow plugs if only 1 of these are off it makes starting harder

Do you have the owners manual? Check in it, if not head to your local mercedes dealership

check air filter, fuel filter, and spark plugs in that order. make sure you check all fluid levels too.

fastest most reliable way to find out what parts are interchangable is to call your local wrecking/recycling/junk yard.... they have books that deal with that issue.

It sound like injectors, if you have enough rev when you pull a way, and loosing power on up hill, must be injectors, dont forget to replace all
