So my problem seems to have been resolved. It was a weird one as i had zero noise on the line from silent phone test and multiple line tests. Broadband was passing tests. My only issue appeared to be severe erroring on the line. Been put on a new port on the cab, new phone socket (OR Master socket 5c) and wires were reseated at the top of the pole. There was odd errors on the line since but DLM has kicked in put me on a 9SNR target and the errors seem to have gone down to a point where i get less than 50 errors over the week on my line. DLM took me off interleave and put me back on fast so nice low pings again.
However i still saw some packet loss on the line annoyingly. So been playing and i have discovered it appears some WAN IP addresses i am assigned seem to get packet loss. The WAN IP i had after the engineer visit was fine and no packet loss until DLM kicked in and made its changes and resynced me. I was getting 10% packet loss give or take when it did this.
So i've left my Vigor 130 in sync and just dropped PPoE session till i get a new WAN IP every time and tested. It was strange because not all connections would have packet loss. For example i could play a online game but have zero packet loss but on teamspeak see about 10% packet loss which made me sound robotic at times. So im currently on a WAN IP that's getting zero packet loss from anything i can see. I've informed Plusnet of this but they seem uninterested.
Anyway this is my connection now. That Red blimp is when i tried to see if i could drop my SNR but at -50, 9SNR is all i can get. Not bad because i'm in sync at 74Mbit/s anyway.
So i'm happy for the time being. I just don't understand how i can get packet loss on some WAN IP's on totally the same settings.
So this was my connection stats after 2-3 days after the engineer visit.

And the WAN IPs i tested:
80.189.69.99 - around 10% packet loss
143.159.102.151 - around 1-2% packet loss
143.159.102.227 - around 3-4% packet loss
83.216.154.59 - No packet loss
80.189.69.115 - No packet loss yet.
So it's strange how i experienced different levels of packet loss then no packet loss on different WAN IPs. But that's what i got atm from recording the IPs. Had more than this but did not record them.
