This is weird... totally stumped me and my dad... I will post what is happening here and see what you guys think...
2.0 HDI 2003 (so hydraulic clutch I guess)
I remapped it ages ago, never had any clutch issues.
Last weekend I changed the drivers side driveshaft and also the starter motor.
Then I drove 80 or so miles, some abuse some not, no issues. Then the fun started...
After cornering (round a bouts mainly) the clutch will start slipping badly in 3rd, 4th and 5th then after driving down the road (straight) for a bit it gets much better although can slip a tiny bit still.
So,
clutch never slips on cold engine
clutch slips a bit when hot, been running for a good 60 minutes
clutch slips badly after a roundabout (happened 5+ times)
Any ideas? cars only done 70k. Tried parking up with handbrake, putting it in 4th revving to 1500 and dumping clutch and stalls immediately.
Is there anything in the hydraulic system that could cause this?!
Thanks !

What are your symptoms for slipping when cornering?

Just after (not on) a roundabout if I accelerate in 4th or something it will slip a lot when it gets to around 2,000 RPM (sometimes it will slip to 3,000+) but then after going along a straight road for a while it will slip very little/not at all even if I try (5th, 2,000RPM, up a slight hill)
Seems like a co-incidence (the roundabout thing) but it is re-produced every time
Seems a bit odd. Going to have a look at the slave cylinder in a bit to see if everything looks right there...

Sounds like it could be diff related. Try turning on full lock in a car park.

Seems ok on a full-lock. Its also perfectly fine until the cars been driven over an hour... I'm just going to put this down to being a 'weird one' until the problem gets worse (and therefore more easily diagnosable). Could a crappy driveshaft in any way cause this as its the only thing I changed recently? (I can't think of a way with my understanding of driveshafts and how they work but I'm no expert)...

Check it's been seated back into the box right, did you refill the box with oil? Any leaks

I think so. We double checked it all, and the driveshaft is snug in the intermediate bearing with the bolts tightened down. I am guessing if it wasnt in the gearbox properly it wouldn't be sat right in the intermediate bearing which it is. No leaks from the gearbox (first thing I checked haha).
Also tightened down the hub nut a bit more, but that seems fine now. This was on the same day as doing the driveshaft anyway.
Thanks for your help all... It is probably just the clutch is at the very beginning of wearing down and I'm in denial. That or a transmission/hydraulic problem which wouldn't be a lot better anyway.
Drove it today, got it to 82c water 90c oil and no slippage what so ever. Its very weird.

Well as always I always like to post back the result. It was infact a worn clutch disc. New kit fitted all sorted!

Note: Slipping, if it happens, around 2000 rpm for a diesel would be the expected point. Clutch slip is related to torque not power. Torque on a diesel is usually increasing very quickly indeed between 1700 and 2200 rpm so between that range is when slip will occur.
NOTE: BHP = (torque x rpm) / 5252.
