Had this EXACT same problem on my DW8, after going through the basics (glow plugs, injector test etc.), found it was valve clearances closed up. Now starts like new.
I think they are meant to be checked every so often, but was never part of the service on mine. Even a peugeot main dealer missed this and failed to fix.
