Are you sure 100% that the one you got is correct?
Here is a link:
Do you know the significance of the "WK" designation? Could that be just a production group marking and not a distinct part number? Any idea why they changed the filter in 2010? Often when they make changes, the new parts are changed for the better and are speced for the older models too. I cant imagine how a filter would change that would not be good for older models too. But I will look into it and see what I can find. I bought that filter over a year ago and just put it in recently. I usually put my car specs in GetBMWparts and use the part numbers from there for Tischer purchase.
Edit: Fuel Filter purchase date from tischer was 12/28/11.
Okay, take a look at this: http://seekpart24.com/mann/fuel-filt...00253&at=21367
It seems to indicate that the 5001 does replace the 519. It appears that I put an older filter on my car.
I am sure the new one is better.
