Hi,
Found this thread via google, so to help anyone else who comes across this, in my case it was the magnetron that needed replacing, part number 12006667.
As per RandomGrinch - the insides of microwaves are not places to be messing around with, so do as I did and get it repaired via Bosch/Neff directly.
New magnetron and all working perfectly. No other parts swapped or work done. My model is C17UR02N0B/02. Symptoms are E1006 error code and only runs for 10 seconds then stops, sometimes displaying the error, sometimes not.
Cheers.
