I've 2 Signums at home; a 2.2DTi Auto and a 3.0CDTi. The gearbox went on the 2.2DTi, but was covered by warranty, so all good. Other than that, the usual boost hoses. Still a solid engine with 120k miles on it.

The 3.0CDTi is to put it simply... crap. EGR, injectors, fuel pump and turbo all replaced in the space of 7k miles (had around 160k miles when I replaced the EGR). Now at 167k it's still causing problems... Pathetic effort from Isuzu there to make a good V6 diesel. My old Vectra 2.2DTi with 200k was pure trouble-free motoring.

My 1.9 CDTi Signum has similar issues, last month the spanner light comes on then the emissions light. Took it in... nothing wrong.

Lights reset but come on intermittently, then last night driving along at 70, went to overtake and no power.

That lasted for about 5 minutes, at which point the engine management light goes off, and all OK... about to drive to work again.. but Vauxhall can't find a fault??

Oh no, after reading all of the previous comments, I hope I am not going to regret buying my Signum.

I have a 2.2 TDi 53 plate Signum, with 86k on the clock. I only bought the car a few days before Christmas and it has already been in the garage all of last week. The crank shaft pulley fell off driving down the road, the problem was the old one was bolted on so tight it took them 3 days to manage to get it off.

Since coming back from the garage, it has developed problems with the power steering, it is very heavy and makes a squeaking noise every now and again.

And now to top it all, the drivers side front seems to make a rattling noise when you start the car, I assumed it was something to do with the suspension or shocks! Does anyone know the code for a power steering pump for my car?

OMG!!! I've just bought 1, then seen your comments, now I'm worried, seems OK, TOUCH wood... I'll replace shocks with spax or something similar if they go wrong, and drive with extra care, can't just afford to change it straight after buying it.

Thanks all for the heads up.

Bought an '04 plate 2.0t with 94k last September, and so far it's been the perfect car.

The service history was quite extensive, all carried out by Vauxhall, and some familiar problems encountered by Signum owners had already been sorted.

It didn't put me off buying the car as it was a great deal, and I'd always wanted a Signum. Have since had a major service and MOT, and only required wear and tear items - three tyres and front discs and pads.

The knocking noise from the suspension described sounds familiar though, and again the garage I use found no obvious faults.

Hopefully will not experience any of the more worrying problems I have read about!

Had the car since Sept 09. It's a Signum Elegance 2.0. Can anyone help me? It keeps cutting out. I drive down the motorway twice a week at 70 mph; it's very scary.

Paid for a 2 year warranty and had an accelerator component fitted 4 weeks ago. Was told this would sort the problem out. It's started to cut out again, losing all power at any speed. The garage I bought it from said they would replace the injectors, but I would have to pay for it. Going to Trading Standards as I don't feel safe driving, as my wife is so nervous, as it could cause a serious accident.

I have had my Signum for two years, it is a 54 plate 2.2 petrol Design model.

Yes, I've had a few issues, had the spanner light last year and the fuel pump was replaced under warranty, those of you who have had X6 fuel pumps, this was probably before the re-design of the part, touch wood the new design replacement shouldn't fail. The boot lock stopped working, again this was a common problem in the original fit part, but again the replacement part has been redesigned to stop dirt getting into it an stopping the ball bearing release in the lock from working. I also had a front spring snap recently, and have had this replaced cheaply at a local Saab independent garage.

But I still love this motor and its ability to eat up the miles in comfort.

Those of you worrying because you've read these reviews after buying a Signum, relax. Yeah things may go wrong, but delve deep into reviews of other cars, and all of them will have a list of problems. I've had a lot of VWs and Fords and they all suffered from their 'regular' faults. Cars are better than they used to be but still not perfect.

Hi all.

I've had a Signum 2.2 DTI 03/04 plate now for 2 years. For the first 3 weeks from purchase it was in Vauxhall as the engine management light kept coming on and the car would just cut out. After 3 weeks and telling me they could not find the problem, I took a Vauxhall mechanic out for a test drive in my own car to show him exactly what happens, sad.

Oh, it turned out the turbo hose needed replacing ideal, fixed.

A month later I was posted to Germany to work, and when I got there, the EM light came on again. I've put up with it for a year and a half again now, and my friend is gonna change my EGR valve for me, hopefully this will cure it.

If the car is OK once this is done, I'm saying goodbye and cutting my losses with a part exchange or something.

I really wish I'd looked at these posts before buying the car for £7500.

I've had quite a few cars, all with their own little problems, but Vauxhall are the worst ever, especially when they can't even tell you what's wrong with one of their own cars.

Thanks, and take care!

Mine too, it was the bearing on the top of the strut.

Hi, I know it's been a while, but did you ever find out what was wrong with your Signum? It sounds exactly the same as my symptoms, but I am not sure where to start. jim_4real@hotmail.com if you can help... Cheers.

I bought a 1.9 Signum Elite in June 2011. Have had nothing but problems with it.

In the 3 months warranty, have had the AA out twice, as the engine went into limp mode, showing a fault on cylinder 3. Was told it was the connector on the injector playing up, but the fault still comes and goes.

Back shock absorber leaked; had to be replaced.

Now as I write this, it is in the garage again, as I have lost power steering on it. Sometimes it works, sometimes not. A new power steering pump with ECU unit is being fitted.

Wish I had never bought it. My old Citroen C5 went on forever, never giving me any problems as bad as I am having with this car.

Present repair is costing in the region of 900 pounds. Will never buy a Vauxhall again.
