Looks like it is a problem because the engine runs 'cold' (all the time)

I had noticed that. The car does take an age to warm up in the morning. I can drive for 30 minutes to work and by the time I arrive it's only about a quarter up the temp. guage. Just after it was serviced it was warming up in no time, but then a few days later, back to a very slow warm up and then the check light coming on.

Didn't Volvo just redesign the EGR valve and start sending the dealers new ones (23 January)?

Was the EGR valve definitely replaced when you first got the code at 5K miles?

What Roy Mc said above is correct - Volvo HQ issued an updated EGR valve and cooler when this issue was identified as a widespread problem, in late 2014. But then in early January 2014, they realised that the updated EGR valves were also giving problems, so they are now using a second updated EGR valve (the updated EGR cooler is still good, my dealer tells me).

Following up on an earlier question. The change on my car has not led to any improvement in performance or economy. I thought it may have done at first but I think that is because I wanted it to. In reality it has had no obvious effect other than the light has gone off and the tortoise is now back in hibernation.

Same here - having done a couple of hundred miles of mixed driving since the EGR & cooler replacement, economy seems to be exactly the same as it was before, and performance is the same too. Which is as it should be.

When I collected the car from the dealer, I thought the throttle response felt a little different but that could have been due to a) spending the previous day in a courtesy car, and b) the ECU re-adapting after the update for the new EGR valve and clearing of previous codes.

I don't get the tortoise as I don't have the smart display ...

Can I just ask, does this light only come on at start-up, or does it appear while driving?

Mine came on while driving. Went off again a few days later on start-up. Car had already been booked in for the replacement parts by the time the light went off again though.

+1, mine came on originally while driving. Stayed for a couple of days, went off by itself then reappeared and stayed on until fixed.

There's no way for me to answer this really as I never saw the "before and after", I keep banging on about how poor Harratts are in Leeds, they did the swap so for all I know they may have just cleaned it. I wouldn't put it past them!
