Signum 1.9 CDTI 150 ( runs lumpy when cold only on idle ?? )

[Longtallhowie]

Can anyone tell me if I need to be concerned about my Signum 1.9 cdti 150 54 plate, When I start up from cold it ticks over quite lumpy for while then it is fine , ticks over smooth when I have only driven about 1 mile or so, when cold it doesn't drive lumpy just on tick over about 750 - 800 rpm. My warranty runs out 1st Sept 07 so would take it in to get check out if you think there might be a problem??

we're in the middle of this with ours right now...VX have so far told us to rev it to over 1500rpm when it's started, and that should cure it.. should you worry.. yes.. take it in and get them to look at it..

keep us informed on how you get on..

Just dropped in the veccy to my dealer, symptoms were rough idle when starting from cold and some lumpiness on tick over when warm,

No fault found, but there is a TIF report for this problem, (i did have a print out and could have given the info word for word- But the wife putting through the shredder this afternoon !!!)

Its to do with the common rail notgetting nough volts on LOW rpm, once rev'd over 1200 the alternator kicks in and pushes higher volts through the system which should stop the lumpy tick over,

It been to warm the last few days to really give it a test, its common on the cdti 150 ! so I'm told
