ok, i am answering my own question for future reference for others. i have had various thermal fuses and cut outs sent to me none of which are right and i believe these are right for some versions but not all. mine has a grey cable with a transparent fused section about 18 inches up from terminal box on inside rear panel, this runs up to and splits between the controls for fan oven and grill. every site i have been to so far does not have this part listed and am trying to find it on beko sites now (they made these ovens) for a correct part as it may have been used on a similar model branded as beko, if i find it i'll post it. my remedy was to get a strand of 2.5 lighting wire and use a crimping tool to make connections, its a bit fiddly at the control panel end but i got my sausage fingers in there, so can you. this obviously cuts out the thermal fused section but all these manufacturers build design flaws in so they have a spares industry.i am sure these fuses are designed to blow if you run fan oven and grill together. anyway this will keep it going til you can get the correct part. at least we can cook over this bank holiday.
