Well i took it back to the garage and asked them to check the glow plugs (although i was convinced it couldn't be, because they were changed late last year)
If this engine (The XRAD) is similar to the XUD (1.7 & !.9) engine then the last offerings from Peugeot chewed up the glow plugs much quicker than the early engines.
This is because they incorporated a much longer post-start glow timer and so they are on for 5 or 6 times longer than previously.
There could be a microswitch on the throttle quadrant on the pump that cuts out the post-glow when you open the throttle sufficiently (saves instant glow plug death) and if you move the cam around so that the switch is permanently 'made' you can cancel out the post glow and (at least) quadruple the life of the plugs
You won't notice any difference to how the engine sounds or performs.[/code]
