Got in touch with tuning diesels. They can supply the connectors. They're on their spares page.

Quick question. While the connector was dodgy did you monitor the live hp pressure?
I am fault finding a friend's TD4. Initially problem of misfire and low power pointed to low pressure pump but having driven and monitored, the lp pump seems OK but noisy, the hp pressure leaps about when misfiring, showing higher pressure at idle then returns back.
Attention turns to the pressure sensor on the rail and the connector, hence the question!!

Can’t get any reading showing a faults
Not put the harness on yet but I am convinced it a driveshaft now ! there only 2 months old
But it’s so intermittent my head is done in
When your friends td4 misfires does it vibrate?

Cheap or non OE drive shafts are know to vibrate. This is normally accompanied by the gear stick shaking, especially so at slow speeds while accelerating.

what would be good replacement parts ? And a recommended supplier?
Only GKN or genuine LR (made by GKN) shafts are suitable. GKN shafts are very distinctive, as the inboard joint has 3 large scallops around the perimeter.
There are some reconditioned GKN shafts about too, which some members have used to good effect.

The problem I have is the vibration is so intermittent it’s hard to pinpoint!
The gearstick doesn’t wobble and when it’s ok it’s definitely ok
The prop is off now so not that ?????
What about back shafts or ird could they cause problem like mine

Those are the worst faults .
So it's not the drive shafts, especially is the gear stick doesn't shake.
That's eliminated then.
Not likely.
It is possible you've got an injector going down at random intervals. Have you checked the injector plugs are secure and corrosion free?

Thanks your post are the best
I am now back to thinking it’s the fuel rail pressure wiring? I have the upgrade part ready to fit ,it make sense with the intermittent nature of my fault but my gut says it mechanical
All four injectors done and zero faults in the ecu
Don’t have access to live reading due to living in Cumbria !
I will try the harness this weekend
I see Nodge has already suggested it, but I had something on my wife's late X-TRail that I could have also sworn was a misfire and was actually an inner CV join. The X-Trail is like the Freelander. It uses a tripod joint on the inboard end of each driveshaft. Quite surprising how it could shake the car, but not always. It was intermittent.

I am in a mess with this to be honest
The drive shafts are new new not recon
And it’s so intermittent it’s difficult to believe it’s mechanical if I am making sense?
I been out and about today with no problems the car turns both ways full lock no banging or clunky shafts
And I am sure it’s as a loss of power when it starts
The bloody Cumbria weather is it’s usually nasty self so can’t see me putting the wiring upgrade tomorrow so one more week till I can eliminate that
Thanks for you input
Yeah, I'm in Cumbria too - not much fun right now! Bit better this morning...
What a strange problem though? When we had the driveshaft problem with the X-Trail, there were no bangs or clunks and it steered fine The outboard CV joints were fine, it was just the tripod joint on the inboard end of one of them (Left Hand I think). Not really sure what else to suggest that hasn't already been suggested by everyone else.

I am putting my hope on the wiring
Then driveshafts after that ?
you can’t really see the sleet in picture but my o my it’s cold
