Tried ADSL/ADSL2/ADSL2+ modes, no significant difference.

Yeah, thought it wouldn't. There's a line fault there, and changing modulation won't fix it.

Me too but it filled some time while waiting for Openreach to arrive.

What kind of SFI bod doesn�t do UG ??

He did UG work, ran out of time to complete the job.

Ah, OK, so he has retained the job for today then hopefully.

Did not retain job: "ran out of time, would of retained job but am on loan and back to my local area tomorrow".
I am trying to find out when the fault will be worked on again so that I can attend.

Openreach have not turned up today. ISP said that I have to make another appointment.
OR are booked for Thu 21 Jun PM.

OR engineer turned up early and ran some tests before I arrived.
He identified a split pair and has moved the line to a spare pair.
Downstream sync is now excellent.

DSL mode: ADSL2+
Line attenuation (dB): D/U 40.0 23.1
Connection speed (kbps): D/U 7979 888
SNR margin (dB): D/U 6.0 11.9
Power (dBm): D/U 0.0 12.8

Many thanks to all those who offered advice.

No worries, the connection speed is great for the line attenuation.
