OK, I know there's been no movement on this thread for a few weeks, however I think an update from me is now in order...
I'm still not getting any BTW speed tests that aren't red, still seeing huge amounts of FEC errors on the line. Last weekend I tried the modem directly in to the VDSL faceplate - it is currently connected via a data extension kit that BT fitted in 2001 when I had ADSL installed for the first time - there was no noticeable improvement to the synch rate, so I'm going to assume the data extension is not the cause of my problem.
Looking at the modem stats, the FEC error count is ridiculous, working out at around 1300 FEC errors per second. Is this even possible? Could the HG612 be misreporting?
I'm using Version 3.0.5306.33566 of the HG612 Modem logs stats viewer & settings editor and Device Information from my modem shows this:
Product type EchoLife HG612
Device ID 1C1D67-21530315408K18040672
Hardware version VER.B
Software version V100R001C01B030SP06
Firmware version A2pv6C038m.d24j
Batch number BC1P6.030.A2pv6C038m.d24j
System up time 5 days 20 hours 59 minutes 51 seconds
I have an engineer booked for Monday 1st September, and let's hope he can actually fix this!

I wouln't worry too much about the BTW speed test showing red.
A lot of users are seeing that at the moment.

As you have a fairly high DS Interleaving depth, you would be unlikely to see an instant improvement in sync speeds.
It can often take many days for DLM to relent whenever there is a reduction in error counts, but it does react far quicker when a previously clean connection starts to see large increases in errors.
The deciding factor would be if error counts reduced dramatically when running directly from the faceplate (preferably via a microfilter plugged into the main test socket).
Sustained error count reductions could eventually lead to increased sync speeds.

That doesn't look too bad for your current Interleaving depth.
Do you have any graphs from when connected directly to the faceplate & are the error counts you do see fairly consistent 24/7 or are there any patterns to when they increase/decrease

:fingers: for 1st September.
It may be useful to harvest/graph your stats 24/7 for a few days if possible.
As happened during engineer visits over many months of trying to track down my connection's intermittent fault, the connection may be fine when tested, resulting in LTOK (Line Tests O.K.), in which case the 'fault' (if indeed there is one) will be closed and/or there is some risk that you will be charged for the visit.
Graphical evidence of genuine 'faults' may assist in ensuring BTOR, via Plusnet, actually pursue a resolution.
As your connection appears fairly stable, i.e. it doesn't resync numerous times on a daily basis, the 'fault' may simply be interference somehwere in the 'D' side cable from the cabinet or even from within your house (Plasma TV, fridge, LED or flourescent lighting, mains power cables etc. etc. etc.
There's not much difference between Line & Signal attenuation values for your connection, so although it can't be ruled out, it doesn't appear to be due to particularly high levels of crosstalk.
My connection now suffers from increased crosstalk over its 1100m or so of D side cable & these are my stats:-
