    Vehicle : Vauxhall Signum

    Trim : Elite

    Engine : 1.9 CDTI 150. Manual

    Year : 2006

    Question Off to look at a 3.0 cdti Siggy - any advise?

    Im going to be looking at a couple of Signum 3.0 v6 CDTIs this weekend and next. Both are facelift 2005/6 models, manual. One has 80+k on the clock and the other has 107k on the clock.

    What should I be checking and looking out for in the mechanical, electrical and interior. Is there anything specific to the 3.0CDTI engine that I need to take into consideration?

    There doesn't seem to be many problems reported about this engine so I am hoping/assuming its very reliable and pretty much bomb proof.

    Thanks in advance for any info.

    As with all Vectra based bodies, check the suspension throughly (springs, shocks, and ARB)

    With the engine :
    Check the revs on idle and then allow to warm for about 10 minutes
    Switch the Air Con on
    Switch the engine off and check the engine oil level (as it should be checked when warm)
    Restart the engine, then take the car for a drive at 50mph, and set the Cruise Control, of about 5 miles
    Whilst doing this you can check all the switches work and that the Air Con has gone cold

    Cambelts on these are due at 100k I think, so the one with 107k on the clock should have proof that it has been changed.
