Strange one, and I would have gone straight to all the temperature affected
components like the crank angle sensor and TDC sensor- i.e. all those that
the ecu looks at to reference engine speed and position. First check all
connections at the starter, PSA certainly use a "starter motor is cranking
the engine" feed back to the ECU, and also the engine block earth back to
the battery. Run another in 0AWG if you are at in doubt, or get more than
0.3v between block and battery -ve during cranking. Bear in mind lots on the
Espace is plastic, and it needs a very good ground back to 0v. If this
starts to rise it will cause all sorts of problems, especially when
cranking- as the starter will be earthing back through the ecu and various
other componentry.
That said it should be a relatively simple task for any technition worth
employing to find the fault, as all one would do is hook up the scanner, set
it to live capture, get the engine hot, turn off, try to restart, and see
which input the ecu isnt getting!
Try another Renault garage!

I was going to suggest a fuel problem. Could you have a dicky cut off
solenoid? Is the battery and earthing ok? My Xantia can be a little
reluctant when hot but only to the extent of requiring 5 seconds cranking
which I put down to the intelligent Citroen designers siting the fuel filter
on top of the thermostat housing. A couple of squirts on the priming pump
seems to cure the problem.

He hates his and was lumbered with it as a company car when a colleague
left. Its underpowered and uneconomical. Still, its a useful size for a
family and great for taking stuff to the dump.
Dont want to put anyone off tho...

Its a DCi- common rail injection.

Mat - mine's a 2.2dci Grand Espace. Sounds like your like me - 3 kids
and mother in law camping, skiing etc. I think its great apart from
this problem of starting when hot which I think is a "one off" fault.
It doesn't accelerate as fast as my Peugeot 1.9 Turbo diesel but if I
wanted a sports car I would have bought one. Its really comfortable on
long drives and cruises at 90+ mph (150kph - you can change the units
for continental driving) very comfortably. There is loads of room in
the Grand even with 7 seats in - we used to have 2 Labradors as well.
I know Renault seem to be developing a bit of a reputation for
unreliability but as a concept the car is perfect for our needs. I
just wish we could sort out the starting - hope that helps. Thanks for
your interest.

Thanks Tim for your comprehensive suggestions - as you say, a
competent technician should be able to locate the fault. I'm not a
mechanic and only have a basic knowledge of diesel cars so a lot of
what you have suggested doesn't mean much to me but I will go along to
another Renault garage and see what they say. I really appreciate the
trouble you have gone to to write in such detail. As I said in the
original posting, It's a real worry now every time we go any distance.
All the best
Gareth
