I do not know why the manual fails to mention the self test.
Yes - mine sometimes shows 3.2 but usually 3.3. Mine also fails the timing test
with an error #4 unless I set it to 1MHz (this may be because of my //e being
a 50Hz PAL model).

No difference - the 9 code just falls through into the 0 code.

Cannot think of anything else (I assume you have the manual).

I do not know the QRAM card but the TW has 256k of RAM to replace the
the motherboard 64k + 16k ROM + at least 2 banks of Aux memory. If you have
more than 128k of Aux memory it cannot all be stored in the TW memory and
I assume it must start caching.

The history behind this: I bought the MPF-III in Feb 84. Some years later
I bought a UDC card and a Cirtech SCSI card and found that neither would
function in the MPF-III (well - actually outside the MPF-III as it has one
standard slot into which I plugged an expansion bus) as it appears to have
a very noisy bus [remember the P8 v1.1 track 0 erase problem? My system
would clobber the disk as it booted if it were not write protected...].

I bought the next //e 2nd hand over the net a few years back and finally bought
the last //e a few months back as I had run out of slots for all the various
cards I have come across.
