What did they do?
Fit a new EGR?
EGR clean?
Reset fault codes?

He reset it, I had already driven in 4th @60 for quite a while which was apparently enough, advised to chuck some redex through it and stick to shell optimax
I would think you will be back to see Sam again soon. 
You might be right.... that might help the DPF, but not the EGR..I would think you will be back to see Sam again soon.
Sounds like a code reset....
So @KevinW ... keep us posted it if comes back. =]
Lol..
Prob EGR related...
Time for a good clean me thinks.

DPF light came on briefly the other day, I think it was trying to Regen but it didn't complete, then it went and this came back on, it's not had a long run for a few weeks, and I've been trying to stick to V power fuel since its last showing, trying to get it pushed into a guy I know as I'm going Scotland on Wednesday night

So van went in this morning, typically the light went off this morning also, plugged in, error read "insufficient flow to EGR" advice was to put another bottle of redex through it and go for a long drive, if it returns get it above 3k revs for 20-30mins. So I'm in Scotland now 
and the lights came back on!!

Have a look at ARCHOIL, its said to be very good for dpf etc.
Archoil AR6400-D MAX Professional Engine, Turbo, DPF & CAT Cleaner Concentrate For PD and CR Fuel systems
There is also an additive for regular use which is said to be better than the old RedX.
I Can't fully vouch for it as I haven't been using it long enough, only time will tell.

Same here (egr) reset mine and it came on again showing insufficient flow was going to take it out and clean it but found Amazon had valeo on there, it’s was £209 bargain ! Fiddly to to change nuts , torx and spline and small top up of coolant . The old is really caked gonna strip it down and clean it for next time
awesome . . . . can you please post some pics of the old caked up one . . . . . ?
Removing the EGR is the only way to fully clean it.
Fuel additives just dont work IMHO . . . .
posted this before, just for an idea of how bad the EGR can get . . . .

Had my van 3 mths and yep I am guilty of doing short journeys to/from work inbetween weekends away. It does regen which I guess is accepted but last week my orange engine light came on (emissions). Panicky I took it for a run in higher revs(!) and a longer weekend run. Lights been off all week (phew). Not sure whether to forget it or get it scanned/checked? Have some long trips to scotland planned and I like to worry!
Soot, Oil and unburnt Diesel from the exhaust starts sticking to the inside walls of the EGR and the valve-plate itself which starts to limit the movement. after a while the soot builds up to the point where the valve cant open or close fully. After that the soot builds to completely block the flow of gasses (extreme case).
The ECU monitors the pressure differential across the EGR using manifold, turbo, up stream temp/pressure sensors. Some newer EGR`s from other manufactures have a position feedback sensors too.
a lot of manufactures are now trying to do self-cleaning movement cycles at the start and end of a run (an attempt to scrap off some soot from the valve itself). They command the EGR to go 0%-100% a few times . . . . you can hear it some times after shutting down the engine and listening for a minute . . . . . it sounds like a throttle plate/body sound.
The EGR cooler is a component used to lower the temperature of the exhaust gases that are recirculated by the EGR system. The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions.
