I can't answer your point directly .... but I hope this helps ...
I too have a Neff oven similar to yours and was able to purchase a
replacement element from a 'Parts shop'.
The outfit stocked lots of parts for most(?) manufacturers' appliances.
I walked into the shop and the 'bloke' pulled out a 'Mechanical' exploded
parts diagram of the appliance which enabled me to both identify the part
(number) required and the 'how to get it out' path to dismantling. {
remantling, as Haynes' says is the reverse of dismantling ). The shop
assistant although _very helpful and knowledgeable_ were forbidden to show
me any wiring diagram. ['case yer elektikute yerself; we can't be liable.
Guv!]
I found the shop advertised in the 'yellow pages' amongst the 'Domestic
Appliance Repairs' section.
I walked in with 'a problem' and after asking, politely, 'Can you help me?'
... walked out with the correct part.

It sounds like the what I think is a shaft encoder (produces pulses when
rotated in either direction) is faulty or the pulses aren't being read.
I've got a Neff oven and microwave that uses the same system - but they're
both new and I haven't had need to see how they are constructed, and
hopefully for a long time yet which is why I bought them rather than
Baumatic. ;-)
All I can guess is that you strip it down and check for dry soldered
joints etc on the PCB. If the shaft encoder is a generic type you could
replace from the likes of RS components. But they are generally very
reliable so I'd look for a PCB problem first - as I said likely a dry
joint or two.
