Intermittent power steering problem...
Discussion
On an 08 Transit 2.4 Tdci rwd. (I know,the shame 
)
I assume it's the pump failing but want to narrow it down before I take it to see a man tomorrow.
Sometimes it's absolutely fine, and until today I'd have said it was only tight turns at low revs ( even then it was generally just a judder) but its worsening. The belt and fluid levels are fine and I haven't noticed any noise (although I thought there was a couple of days ago, but we were next to an artic...)
Any ideas? It looks like there was a recall and my van has had the bit fitted.
And it's only done 10k

Might sound a bit random but have you checked your tyre pressures? The mother said the PAS was failing on her Passat. I have a look and the fluid etc was fine but the steering was juddery when stationary and didn't feel 100% when manoeuvring slowly. Front tyres were only around 15psi
Yep, it's odd. It started badly this morning, then was absolutely fine for a bit, then broke for an hour or so, and then worked fine for the last few minutes until I needed full lock. I did switch off and back on a few times, which corresponded with each change, but it's a bit perculiar.

If it's occurring when you hit full lock it could be a faulty/sticking pressure relief valve in the pump.When you hit full lock flow stops and the valve opens, perhaps it's getting stuck open and giving no pressure to the rack afterwards until it's got no pressure (when you switch the engine off) where it settles back again.
It's not that consistent, annoyingly. It seemed to be only after a turn or so of lock, so small to medium roundabouts or around campsites, until yesterday. Interesting thought about the valve, I'll have an experiment when we move again.
Thanks for all the suggestions, I wish it was just the tyre pressures
Now, anyone know a good garage near Perpignan?

So you're saying you're too much of a nancy boy to make it back to Blighty without PAS?Thanks for all the suggestions, I wish it was just the tyre pressures

You'll be asking us to come and adjust the mirrors next...
Had a brand new 2002 Astra van with random power steering shutdown. Pretty unnerving and dangerous when it happened mid corner as its much heavier than normal unassisted steering, turning it off and on again got it working again for a bit. It was due to the alternator wiring being loose according to Vauxhall. It happened again so they replaced the alternator. Not sure if an electrical fault would cause the same on a Transit or if Transits have good old purely Hydraulic PAS.
