Totally non the wiser yet, new mechanic said be better if i can replicate issue and get X5 to him whilst it exhibits issues,especially as I guess he reset all codes, tad worried as doing the drive to him in limp mode that took me 30mins today in normal drive mode means can take me anything from 45-60mins in limpmode, mainly urban driving bumper to bumper

That's rubbish - it doesn't need to be in limp mode for the mechanic to read the codes. Even if you stop and re-start the car and limp mode goes way, the codes will still be there...

Ok makes sense but first mechanic reset i believe and i was not in limp mode after this, then this second guy read codes and reset he said, can transmission temp be acquired via the scanner tool? Think he wants to check that and take it from there if high well got bad low fluid and or knackered components....in which case i decide risk the fluid change or leave as is in case makes issue worse as its at 117k and never been done...btw one thing i havent tried is sticking car in manual mode when going down steep hills see if the trans fail mode pops up....or sport mode for that matter...coasting down hills that are steep seem to be trigger for limpmode....
