Vauxhall Signum 3.0Cdti Auto V6

[Msd0115]

Hi all, this may be a long shot but my Signum 3.0 cdti auto revs but is fairly gutless and isn't pulling as it should. I'll get the odd surge of power then it drops and then returns and judders here and there. Had this issue before but it was the fuel filter sludged up. This was replaced and worked a treat after that for a few weeks, but the symptoms have returned. Appreciate any help cheers

If you have let the fuel level in the tank drop low it may have dredged up a load of gunk that has blocked the filter again. I was told not to let the fuel level drop below 1/4 full for that reason.

Agree with Shoota: my Saab definitely runs better when it has a decent amount of fuel in it, and I never let it drop below 1/4 full.

Worth checking the pipes on the turbo and the intercooler ( look or feel for splits ).

Thanks very much i'll bear that mind, appreciate the quick response from you both, cheers.
