There shouldn't be any "battle". When I sent my D600 for warranty service (lots of dust and oil), I simply stated that there was debris on the sensor that could not be removed with the Self Clean and a blower bulb. The camera came back in 10 days with a new shutter and a clean sensor.
Send it in, you will likely get a new shutter. You will get dust afterward, every DSLR does. You shouldn't get any more oil.
I am pretty sure that if you send it in after you tell Nikon you cannot keep your sensor clean, Nikon will replace the shutter. Forget about getting them to admit anything, and why should you care at this point? You are going to wind up with a brand new shutter in a great camera.

I don't know that some dust after 4000 clicks is abnormal (unless you're seeing them at f/4). I've been shooting DSLRs for 10 years and after paying a local shop $100 to clean my D100 (about 7 years ago), I learned how to wet clean a sensor.
So, maybe you don't have a warranty issue, just a usage issue that requires periodic maintenance.

Think of the Nikon cleaning as buying a 6-month warranty extension on your camera. As a bonus, they may replace the sensor while it's there. If not, you get your camera back with a clean sensor and have an additional 6-months to see if it gathers excess debris. If it does, you can ask again to get the shutter replaced under warranty.
There is a possibility that the dust you are seeing is a normal accumulation and that the current shutter is fine.

Be sure to mention to Nikon that the oil splatter is NOT dust by any stretch. I had my D600 repaired twice with no effect. Nikon Canada then sent me a brand new body, and within 200 frames, the oil spots returned. I demanded a refund after escalating my issue with the company. They sent me a cheque a week later. In my experience, the camera is junk. I'm waiting to see how the D610 or Df fares over the coming months.
Best of luck getting this issue resolved to your satisfaction.
My D-600 was showing lots of dust/oil which I could not get clean. I had purchased it last December and it had approximately 2,700 clicks. I called Nikon Service Center in LA and they said to send in a few shots showing the extent of the problem. So I took a number of shots at the blue sky from f22 to f11. At f22 there were a substantial number of dust/oil spots and by f11 only about ½ of the spots were visible. After sending the photos to Nikon Service I got an email to send in the camera and with instructions to download the prepaid UPS shipping. I send it in on a Wednesday and by Friday I received an email indicating they had received it. Since it was the weekend I figured I would wait until the following Tuesday to follow-up. On Tuesday morning I received an email from Nikon Service indicating the camera had been shipped. I received the camera two days later and the Invoice Repair indicated a B2 repair which included the following: Replace Shutter mechanism Clean Bayonet Mount Checked Auto Focus operation, Mirror angle, Flash operation, Image check, and general Check & Clean
No charge for any of the service. The total time from when I first contacted Nikon and received my camera back was 10 days. So far the replaced shutter mechanism is working fine and I am not experiencing any dust/oil issues.
I would recommend you call Nikon again and offer to send them some pictures showing the extent of the problem. My experience is that Nikon will not admit to a problem but are proactive insofar as replacing the shutter mechanism. Good luck Gene
Bill... I just recently sent in my D600 for a sensor cleaning and Nikon Los Angles replaced the shutter mechanism and did a general inspection. I used their web site to initate the sevice process and didn't speak to any of their personnel or request any special service except a sensor cleaning. So go for it before the warranty expires.
I live in Paris and had my D600 returned twice to Nikon Service Center. The second time, it came back with a dirty sensor, just out of the box. I did not even take any picture.
After searching the Internet on French website, I decided to send a mail to Nikon support asking for a definitive remedy to what seemed an unsolvable issue.
I got called back by Nikon after-sales service and they offered me 3 solutions, basically confirming what I read on internet:
1) They just received a new cleaning method from Nikon Japan to solve the issue for good (yeah it took them 1 year to get to that). She offered me to have my D600 cleaned using this method.
2) To exchange my D600 for a new one FOR FREE
3) To exchange my D600 for a bend new D610 in exchange of EUR250
I chooses option 3 for my peace of mind. In addition to the dust pb, the filter on top of the sensor had small scratches (I got it brand new like that) and I had the feeling that the more the sensor got wet-cleaned, the more visible the scratches. So I do not to want to take any risk.
I do not know if it is something offered outside of France.
