Specifically... These ones.
I'll be testing for intermitent cables on the extruder after the current print finishes, but it'd be great if someone with more experience could point me towards other possible causes.
Oh and I have indeed done a PID Autotune.
Cheers 
That is most definitely a bad connection. I would heat up the nozzle and and just grab the cabling at different points and slowly move them around to see if those dips occur from cable movement. You could have a short/open anywhere from the thermistor bead alll the way back to the connector on the motherboard.
Hmmm,
Haven't been able to replicate the drop by jiggling, pulling or just generally shaking things.
More testing....
Managed to print one small calibration cube, but it's since gone straight back to hell.
Getting Repetier errors now.
Thoughts anyone?
I had a similar problem. I ended up taking the wire wrap off the wire bundle and found a small cut in my wiring. It was from the wire bundle rubbing against the metal angle brace along the side. It was difficult to repeat by moving the wiring unless it was positioned just right. After I found the cut, I soldered the wires together and put heat shrink over the splice. I haven't had the issue since.
She's dead Jim.
Oh well, it's a good excuse to save up for an OrdBot Hadron
Not that you shouldn't save for an Ordbot but couldn't you just order an E3D?
Already done!
Probably have to replace the extruder motor and fan as well, I think they might be dying(overdriving fan etc etc)

Perfect excuse to upgrade to a Bulldog XL
Why the hell didn't I think of that?!
In that case throwing the current carriage out is probably on the cards too.
Hmmmm, what would you say the total cost of replacing said carriage would be? The printable version, of course.
Are you talking about one of the one's I designed? That is a quick and easy print and you wouldn't be the first person I have had to send one out to. You'll never look back and that carriage will accept the regular Bulldog also (if your looking to save a buck). I would seriously recommend the XL though. Even without the 1/32 stepper it pretty much eliminates Moire.
You looking for linear bearings

Or Stock SD Rods and carriage

Yeah I guess the ones you designed would suit!
I must admit I've not really done enough research into the replacement parts to know what's what.
I think I'd like to throw out the original rails etc etc so I'll have to look into Lawsy's replacements as well.
It'd be awesome if you could send said part to me, if it's not too much trouble.
Shall I get in touch when I've actually got some money?

So the first one in the above post works with lawsy's linear bearing conversion. You use the Lawsy's parts for the Y-axis and Mine for the X-axis. It is just a little more user friendly with the Bulldog and E3d.
Let me know when your ready.
Right! Thanks mate, I'll be in touch in a few weeks
