So I had gathered my tools and parts for my first attempt on an oil change for my 2010 W204 C250 4matic. This included the Mann HU718 filter which many recommended.
When I took the cap off to do the oil filter change I found that there was a MaHle OX 345/7 filter in place within a slightly different housing to that I've seen in pictures. The Mann filter was also too small to fit through the central spine of the filter housing. Thus I put the old Makle filter back in.
I'll probably order a new one.

Is this a norm for my car or may someone have changed the filter cap from the original?

 

The HU 718 filter is fleece for V6 engines.

 

Thought mine was a v6, what's mine then, a 4v?

Changed the oil anyway. Only got about 6L out so put same back in.
New Makle filter ordered

 

Sorry, Caught out by Benz nomenclature & MY I think. Is yours the little 2.5 litre V6 & not the inline 4 cylinder M271 Evo Turbo engine? Both called C250's. The small engine never came to SA ~ only 3 litre & 3.5 litre.

If it's the 2.5 litre M272 V6 I have no idea why your filter is different.

 

I've no idea either. That's why I'm asking.
Anyway just ordered a new Makle filter

 

That's strange. According to the online sources I've looked at, Mahle OX 345/7D cross references to Mann HU 718/5x. Another words, they should be direct replacements.

 

Is the Mahle filter also a blown polyester "fleece" type filter like the Mann + Hummel?

 

Appears to be though has a more sturdy housing on either side
