twice now in the S210 320CDi, it's managed to get itself into neutral while pulling an overtake move from about 40 mph. Starts off by downshifting as you'd expect, (not talking kickdown full boot) then seems to get into neutral rather than driving. let the revs drop back to idle and it goes back into gear and works. If I try to replicate it when not overtaking, naturally it doesn't do it. Previous owner had the oil and filter changed, so shouldn't be that although I've not yet checked oil level. Box seems to perform as it should all the rest of the time, too - not getting flare changing gear or anything, or undue slip.
Any thoughts? common fault?
