Which Belt?

Have a look on Autodoc. Belt spec differs depending on things like aircon PAS fitted Etc. Or just go to MB

Have a look on Partsouq and use your VIN. It should give you the exact part numbers.
If it's just the belt, I'd ask Mercedes or mercedes Newcastle/Edinburgh for a quote via ebay using your reg No. to guarantee the exactly correct part for probably not much money.
I have to ask though, why just the belt?
If the pulleys and tensioners are original (10+ years?) have you considered changing these also?
I've bought a gates kit with belt and all tensioners, and I'm hoping to get those done over this next week, storms, rain and sub-zero temperatures pending. To get access, I need to remove the radiator. I'd need to look up whether this is required to replace just the belt (due to very limited access - have a look down the front of the engine!). If it is a lot of work to get to the point of being able to replace the belt, you could consider replacing all the pulleys.

In fact, I think I posted a thread a while back comparing all the prices on these.
If I was getting belt only, I'd also go with Merc.

Help Please W212 E350CDI OM642 Seprentine Auxiliary Belt Replacement | Engine
So possibly only £30 for a genuine belt! Why go aftermarket at that price?

No such thing those....they dont make belts they pay others to supply them....amongst other they use are...Continental, Gates Dayco, Cal-Van Tools, CRC Industries, CTA Manufacturing, Hutchinson, INA, Mitsuboshi, Mubea, and VRP Speed. (List found on another MB site!)
So pretty much anyone that quotes the right spec/price!!
We all know that any part that comes in a Mercedes box is way better than any other make ? I mean they must be better as they cost loads of money and MB tell us how goog they are 
Update: got an INA kit off Autodoc for £75 ish which came with the tensioner, the belt and 2 guide pulleys.
Did the tensioner and pulley with no issue but could not get the 2 guide pulleys off of the car. Infact one snapped my hex bit in half so I gave up on them.
Started the car and still have the bloody squeal

If idler/tension pulley is old or original change it.
Can and do let go without warning causing more problems.
Had this with CLK years ago.

It's the 2012 E350 CDI, which is the OM642 engine.
Access was a right pain. Well, the access is fine, once you've removed the batwing, air ducting, front slam panel, turbo charge ducting, resonator box, passenger side top coolant hose, undertrays, drive belt cover, crank pulley cover and radiator fan.
Update: driving car yesterday and battery logo flashes in red on dash and power steering becomes heavy 
Luckily kept the old belt so stuck that on this morning. Fingers crossed this one behaves itself.
Any ideas why the new one would’ve come off and shredded slightly? It was all seated correctly and lasted about 20miles

Normally its because it was not seated correctly on one on the pulleys.....just one groove to one side on one pulley will destroy it really fast and its easily missed. I will admit to doing thing on an old Discovery!! 
Update: lost the belt again this morning. Got it back onto the drive and seen that the belt isn’t just shredded but in bits! Also oil everywhere!?
Any ideas guys?
Zero funds to take to a garage at this time but would be nice to have an idea of what’s going on. I can’t believe a second belt has shredded due to it being incorrectly seated AGAIN? Also all this oil
Thanks everyone
