I have posted this in the appropriate DPR thread and is a continuation of the NikonCafe thread at https://www.nikoncafe.com/vforums/showthread.php?t=110976 You may recall my camera was returned to Nikon UK with the 'Err' fault and they sent me an estimate for 231 uk pounds to replace the shutter. I have discussed this at length with NPU customer service pointing out the results from the DPReview thread and that my camera has only done 3000 shutter actuations even though it is 2.5 years old. They tell me that on switch on and at the first shutter press the camera performs diagnostics. Any error during switch on or shutter operation will result in the 'Err' message. Although it may seem that there is a single fault with all our cameras there may in fact be a number of differing reasons why we get the 'Err' message. Many errors are tiny/trivial and will not prevent successful operation which is why the camera goes on to function perfectly for the rest of the day. They are in fact aware of many professional shooters who are living with the 'Err' message without it ever progressing to a shutter failure. The shutter however is an unservicable unit and if the fault is to be eliminated it can only be replaced as a whole. In my particular case they accept that the camera has done *very* little work and were prepared to negotiate on the repair price. We came however to another understanding. Early in the camera's life I had the metering system go wild. Huge overexposures which changing lenses, cleaning contacts, changing batteries and resets failed to cure. I knew of the metering issue and sent it in for repair. At the time however they could not replicate the metering failure and sent it back unrepaired. After that the problem never recurred. Anyway the accommodation we have come to is that I will pay for the shutter repair and they will change the metering system even though it is presently not misbehaving. This at least leaves me with a camera that I can have some confidence in. Not a perfect result. Not one that helps anyone else I guess but it works for me.
