Glad I found this thread, I had the P010D-00 fault code today but thanks to the OP and also the Powerful UK vid have got a diagnosis and know what part I need.

Thanks to all the contributions on this thread, had the same error, changed the B MAF and all sorted.
For info bought a Seimens branded one from GSF. in stock and only £88, it looks completely OEM and works perfectlyMark

For anyone that finds this thread in the future:
My Disco 4 had the CEL on but no reduced performance and the IID tool flagged up code P0103-17 Mass or volume air flow circuit high input - General electrical failure - circuit voltage above threshold.
Accordingly I found this thread and Simon's PowerfulUK video on YouTube.
I changed the sensors around and the fault code changed to P010D-17 Mass or volume air flow B - circuit high - General electrical failure - circuit voltage above threshold. so I knew it was one of the MAF sensor's and duly got an OEM part from Maltings.
After putting the new one in 'B' and what should have been the good one in 'A' I had no power but no code but a CEL on the 2nd engine start. When I switched them I got the original fault back but full power along with the CEL.
So after some head scratching I put the old 'A' back in position and the new MAF in 'B' and hey presto full power, no engine light and no fault code.
TLDR in my case it was the 'B' MAF as identified in the video that was faulty but with the P0103-17 code.
It may well be that the car identifies the front most MAF sensor as 'A' and the rear one 'B' which would have made perfect sense if not for Simon's video.
Hopefully that makes sense and saves someone unnecessary time and money.

P0033 (2F) vs. P0033 (28)
Hi. I have fault code P0033 (2F), which looks to have the same description as the (28) variant I also see posted.
I have reseated the connector pictured below, and sprayed in some contact cleaner just in case, but the code came straight back.
Any suggestions where to look next?
Where are the other ends to these wires - if it's worth checking them there too?
Thanks.

Bump
Can anybody please advise on the difference between these two fault codes:
P0033 (2F)
P0033 (28)
and probable causes of each?
