Vw powerboat with 3.0tdi v6 with vcds codes need help with a fix

[stuartmvw225]

Hi I own a VW 3.0 TDI V6 Boat with engine code BSP ( Same as BKS in VW Touareg ) I need a genius !! ( please treat as a car the boat makes no difference)
basic history is only owned for 3 months and it was always hard to start after it had been left for 48hrs + , once started it will start on the button all day long .( doesn't use glow plugs) .
one afternoon whilst on boat it just stopped as if key had been turned off - hasn't started since .
A mate loaned me his VCDS LEAD and LAPTOP and this is what faults are stored but I don't know what they mean or what is likely to be wrong can you help ? ( couldn't down load pictures of vcds screens taken on my mobile as files too large so typed out info

I have cleared the faults by using VCDS and as soon as the ignition is switched on they all come straight back

Can any body help in anyway or explain what to check or if based near Essex can you come and take a look ( VW Marine dealers not easy to obtain ) , please treat this fault as a car the boat makes no difference .
pulling my hair out now

many thanks in advance for any help / advice given

Welcome to VWAF

With the 2.7 TDI V6 P1195 or P1281 indicate a wiring loom problem. I suspect (but cannot be sure) that you've got something similar.

P3348 also suggests wiring see this link on the Ross Tech Wiki for more info >>> 19804/P3348/013128 - Ross-Tech Wiki
