Pelle,

I just went through the same issue. I thought I got the wrong filter as it was about half the length and a little smaller in diameter. The old ones were black and the new ones are blue. I actually returned it, as I bought it in a bundle with filters for all my other cars and thought it was an extra or something. When I went to change the oil on my 1988 300E, I couln't find the filter. So I went back to the dealer and found out the one I returned was the new filter. I put it on today and the thing fits, the seal seals and apparently the filter is doing its job. Maybe the oil that spills out when you change them will be less next time. Good Luck, Jim
