I’m sure Lord Opti can help... We all know he’s a closet “canal boat fuel” fan :-X :D

Based on god awful Vectra-C, surely better options out there?

What to look out for etc.
Crank pulley failure on the 120 bhp lump.
Inlet sooting up causing a rough idle and sticking EGR valve (not necessarily in that order) 150 lump.
DPF clogging if fitted. Also check it still has one if it should... '56 on iirc

Auto box is horrific, especially in snow.

Otherwise, a roomy 4/5 seater with a reasonable boot. Later cars follow Vectra for spec. Elite has full leather, heated front seats and Nav. Middle rear seat is a token effort 40/20/40 split, so not great if you regularly carry three in the back. ;)

If you find a Vectra C with the travel assistant, you’ve found a unicorn and you could flog it on the owners forum for silly money! Increadibly rare to find it in a Vectra and as the Signum version base doesn’t fit so it’s not an easy upgrade. Signum is only really a 41/2 seater anyway so travel assistant makes little difference


On all the 1.9s the water pump is weak link, it weeps, bearings rust and eventually fails. Imperative the water pump has been changed with the timing belt.

DPFs were only fitted to estates and autos look on plate on drivers door pillar, bottom left, iirc, 0.50 means DPF fitted, 1.20 means no DPF

AF40 auto box is bullet prof and as long as you don’t act like a tit no problems in any weather, never had a problem with my AF40 and it’s got well over 250bhp running through it.

M32 manual 6 speed that is the manual option on ALL the 1.9s and is very weak. Upgraded internals available, around £400 and a days work at a specialist.

Everything else to look for is like every eurobox of the time

Does the travel assistant hand you beers from the back seat? Scantily clad nubile female? No? Then who'd spec that..  :D

Having put a mere 196k miles on one of the 150 bhp ones:

Manual - Can suffer DMF issues and the M32 box can have a bearing issue, that said mine was on original clutch and had one flywheel under warranty at circa 50k miles. There is a modified M32 end plate which was released circa 2012 ish, this can be retrofitted and has larger bearings and improved oiling.

Inlet, well mine was original, it was a bit crudded up and would have benefited from a clean/replacement but was not causing any issues, it had been fitted with the brass pivots for the actuator rod which means it never suffered the issue where the rod popped off.

EGR, I had a spare which I kept clean and swapped them over at every service, never had any issues as a result (and its easy to change and clean).

It did have two new injectors and one glow plug.

Never had any issues with the DPF (they are no worse than any other DPF fitted vehicle), the pressure sensor pipe did split (but its easy to fix with a bit of fuel hose)

I found it a pretty good engine

I read, when the signum was first released, that it was meant to be a car that you were driven in, as opposed to a drivers car. WTF Vauxhall got that idea from, I'll never know. Hence the travel assistant. A box of tricks that sat between the rear seats with a fridge, for you cold drinks, and other various compartments to make your journey more comfortable.

They could stick, I never had that issue and there was a modified manifold fitted after around 2006/7 ish (which I expect helped).

Unlike the Bavarians, they didn't suffer ingress of the flaps

My early facelift was booked in for it's second manifold in 5 months when I wrote it off ::)

Might be a more reliable engine if you're doing mostly motorway work...  :-\

Thankyou all!

It's an option at the moment, Looking for something for Mrs VXL as a daily run-around, with few longer trips thrown in each month and something capable of having the Dog cage in the boot when we go on Holidays / days out.

Basically she sold her Sharan over a year ago as we knew it would need a bit spent on it at the next MOT and as all series II Sharan/Alhambra/Galaxy vehicles are now reaching 'rust the chassis rails / floorpan / sills' age it wasn't really worth investing any more money in, we also had my eldest son and now my stepdaughter reaching 17 within 12 months of each other so we just bought a 'throwaway' Corsa C 1.2 SXi for them to learn in and seemed sensible for Mrs VXL to use it instead of the Sharan....  Roll on 12 or so months and the eldest Son passed his test and has a Fiesta and the Stepdaughter is well on her way to passing her test and has a Corsa D 1.2.... So we only have my younger son who relies on us for transport. The Dog also travels on the back seat of my Omega using a harness when we go out but ideally is better in the cage in an estate / hatchback than the back seat with a strap really.

We've been looking at Astra Estate's - mainly 1.6's (which after Terry's issues i've lost interest in) and 1.7DTi's which all seem to have racked up the miles and you struggle to get anything other than base spec..... Signum seems to offer a bit more kit and comfort (Plenty of Design and Elite spec machines out there) and the 1.9CDTi engine for a lot less money.

Based on god awful Vectra-C, surely better options out there?

'It's not my car'  ;D - I will only drive it occasionally, my role is to change the oil and filter and blow the tyres up!

Crank pulley failure on the 120 bhp lump.
Inlet sooting up causing a rough idle and sticking EGR valve (not necessarily in that order) 150 lump.
DPF clogging if fitted. Also check it still has one if it should... '56 on iirc
Auto box is horrific, especially in snow.
Otherwise, a roomy 4/5 seater with a reasonable boot. Later cars follow Vectra for spec. Elite has full leather, heated front seats and Nav. Middle rear seat is a token effort 40/20/40 split, so not great if you regularly carry three in the back. ;)

120BHP - is that not the 2.2DTi? That was the common problem with all 2.2 DTi's along with the auxbelt tensioner failing - Been there - three times with Omega DTI's  :-[
Inlet sooting up, EGR valve - well it's a canal boat fuel so pretty much the norm - MDTM seems to have the solution to the EGR problem, would probably acquire another EGR and follow his method   :y
Yep, would only be looking at a manual, Mrs VXL likes archaic technology, hence why she married me.  ::)
Stuff 'em - two of them can drive themselves, well one, but t'other one getting close!

On all the 1.9s the water pump is weak link, it weeps, bearings rust and eventually fails. Imperative the water pump has been changed with the timing belt.
…...
M32 manual 6 speed that is the manual option on ALL the 1.9s and is very weak. Upgraded internals available, around £400 and a days work at a specialist.

Well it would be getting a full service by Serek soon after purchase no doubt so hopefully waterpump can be ticked off, as i'm getting / feeling older life is easier to take the thing to Serek and i'll just do the usual Oil and filter changes inbetween  :D

Gearbox.... well, I guess that's luck of the drawer, although most used car dealers will give you a three month engine and gearbox warranty...  :-\

It did have two new injectors and one glow plug.

Never had any issues with the DPF (they are no worse than any other DPF fitted vehicle), the pressure sensor pipe did split (but its easy to fix with a bit of fuel hose)

Glow plug replacement quite common on higher mileage canal boat engines I've found  :y
Injectors doesn't sound so great as I imagine they are rather expensive.  ???
DPF - Ok, well if it's no worse or better than any other then no room to complain I guess.
Pipe splitting - well, 2.2DTi's were forever splitting vac pipes etc so I guess nothing new there..  :y

120BHP - is that not the 2.2DTi?
They did a 120bhp 8v common rails diesel as well as a 120bhp and 150bhp 16v common rail

Badge colour and oil filler location are two ways to immediately identify

Of course if it’s only for short runs with the odd long one and you want toys I know where £1600 will get you an 06 2.8 v6 turbo petrol Signum  :D  :y

Facelift cars only have three diesel options... 1.9 120 8v, 1.9 150 16v and 3.0 190 v6

Not going to get into an argument about specs etc, but I know that I am right for 2006 on as I was looking at new Vectras at the time and the Signum was bundled in with the Vectra in the brochures... Which I binned when I cleared my room out last year.

My experience of the 1.9 150 16v lump in both manual (30k) and auto (15k) guises was less than positive, hence all the Vectra Cs I have subsequently owned were deliberately 1.8 petrols which I will defend to the end of days.

The Signum is a Vectra C estate with a funky rear seat and slightly smaller boot.

For the needs you suggest, facelift will be perfect, especially in Design or Elite specs and with whichever engine you can find looks best in Moonstone grey metallic or Reubens Red 8)

Shop around and buy on condition regardless of engine  :y

Incidentally all have 100k cambelt, except the V6* which are  chain driven

*I know the 3.2 is belt driven, but early cars only, and I have nowhere suggested buying a preface lift Vectra C of any shape ::)

Cool, thanks for that  :y

Think we are looking for a facelift around 56/06 upwards, with the 150BHP Engine in Design or Elite trim (I really need to get a brochure to get a grip on the specs.

Cambelt is easy to do, you change the water pump as a matter of course with the cambelt kit (as you should do) then you don't get issues.

If you got a 150 I may well have a pile of spares you are welcome to (I expect it includes a clean spare EGR to)

My wife had a 1.9 cdti Signum Elite 2007 from almost new to 85000 miles in 5 years. Problems were the clutch damper which is a 2 part thing. We had 2 of these under warranty. It had spring and shock absorber issues (like Vectra) but was a great car.
