Can anyone help me? My 1.9 Signum is losing power every now and again, but no lights come on. When it stops, I wait for a few seconds and it starts again. I think it might be the fuel filter, but not sure. Can anyone help?

I have a Signum 2.2 petrol - I think it's a 55/56 plate (can't tell you as I haven't had it long and it's with Vauxhall at the minute).
This was the best car I have owned until the warning light came on (car with spanner through it). I will be driving and suddenly it slows down, no matter how much power I'm trying to give - and then it suddenly cuts out. I have 2 daughters and I also drive my very small nieces around. Driving this car has now become very scary for me.
I like to go out places - but now I only dare drive to and from school.
Vauxhall, first of all are conning you know what's, and have called me saying they can't find a problem - so I'm paying over £100 just for them to look at it and say "we don't know"... I thought these were professionals???
Anyways - can anyone at all help me out?
As I said, I'm driving and then the car slows, cuts out completely and refuses to budge for ten minutes, and then will repeat.
Please help - I don't have a lot of money and Vauxhall have treated me like crap, and I don't know what's happening to it.

My neighbour had the exact same problem with her 2.2i Signum. It would cut out and not start again for 10 - 15 minutes. Turns out the oil was so low the car was cutting out to protect the engine. I hope Vauxhall have checked this for you, but I would defo check your oil level.

Hi, I have a Vauxhall Signum 2.0T 2004, which has done 86k, and recently had a problem while driving. The car started to judder like it was struggling for fuel, and also cut out when stopping. It loses all power while it is doing this too. Not sure what the problem is, but the engine warning light has just came on too. Would appreciate any help and advice.
Many thanks, Lee

I had the same problem. Mine was the vacuum pump on the brakes, because I noticed when this happened, that the brakes got very hard.

Hi Emma, sorry for the delay, however I have only just seen your post today. You have a known Vauxhall problem & it is either the fuel pressure regulator or the petrol pump. I had several of each replaced due to this fault, & the problem is now sorted. You should go to Vauxhall direct & ask for a subsidy as this is a known issue. Good luck!

I have Signum 2.2 petrol, It goes 30mph and then loses power, and then works again for about 5 minutes. Then does it again. Any ideas, and how much would it cost to fix?

Hi all. I have a 55 reg Signum 3.0 CDTi. It's awful; the electrics are terrible, my central locking is completely broke, my boot doesn't work after changing the button and mechanism, and it's now got a fault for the DPF, and the car keeps juddering when accelerating. And if I push it too hard, it goes into limp mode and I lose the turbo. Anybody know how to resolve any of these problems, or know if anybody wants to buy one as spares or repairs? Cheers guys.

Hi, I have a 2.2 Elegance CDTi. It's nothing but trouble. We tow a caravan, and on the way down the turbo cuts out and we have to stop and restart the car.
My warning lights come on saying need new bulbs, I have had a new steering rack, and many other things. I need a new car.

I had the same problem with my 3.0 V6 diesel Vectra C. It was found that one injector was faulty, and after an expensive replacement, everything was fine and back to normal. You can buy second hand injectors on eBay for around £45 each, and if you are willing to spend an extra £25, you can have them rebuilt and tested by post. Much cheaper than the new Denso injector at £300+.

Hi all. I recently purchased a Vauxhall Signum 1.9 CDTi 150 BHP on an 06 plate.
In the first week of ownership, it was a great car; very fast and responsive, but had a slight whistle on the revs on starting. Then the symbol came on in speed clock area, a car with spanner, so it went to our local garage and it had 4 new injectors and DPF filter, very costly. It came out and a few days later the light was back on with no code. Seems like the turbo is not working now as there's no power kick in at 2.5 thousand revs, and the whistle has stopped, so have purchased another turbo and got a full service kit including cambelt and tensioner. I'm hoping this solves its problems as it has cost a lot so far, and I'm thinking of giving in if it comes on again after this, as I can no longer fund any more parts.
