Hi

I have been told I need a new Inlet Manifold Kit (PartNo: 555 625 19) for my Vectra (55 reg, 2.2 petrol, automatic).

The garage (a national chain) ordered it 2 months ago but could give no time scale on delivery as it was a special order item that needed to be made.

I gave them longer than I should have before chasing them up but I called them this week. They were upfront in saying they had forgotten to chase it up with the supplier but in any event they now use a different supplier.

The new supplier wants the full cost of the part upfront, but they cannot give a timescale on it until its ordered. It could be days or months and no way to know, until I hand over the money (around £400).

I know the car is ten years old but they are saying this is a fairly common fault and it is quite a common cart. This situation seems ridiculous to me, surely there is a better way than this. I would like to avoid the main dealer if possible.

The car is in good condition and I am happy to spend the money on it to keep it going


Any suggestions?
 
Obtain a second hand part is an option but I'd always be concerned about faults with the replacement...

Cant believe anything for a 2002 Vectra is made to order though, I think someone's having you on personally, what dealer group is it, you say it's a national chain? The 2.2 lump is pretty common and GM usually have a pretty good parts network. What is the actual part that needs replacing? An inlet manifold 'kit' seems an odd one, assuming it's a complex 'variable length' manifold design it will have numerous component parts but the parts inside the manifold that move (the only bit that can really stop working) should be simple to replace and readily available? There will be a vacuum operated solenoid or an electronic actuator that bolts on to the manifold one assumes...
 
I am not particularly handy under a bonnet. Is it something I can do myself, or should I really find someone who defiantly knows what they are doing.

The garage I mentioned won't use a part from somewhere else.

The fault has been present for a while, Engine fault light comes on if I put my foot down. Fuel economy has dropped too. The problem I had was the fault code was not being stored so garage had no idea what it was.

I eventually bought a diagnose kit and grabbed the code when it was live: P1112 (which I think is swirl flaps).


The garage says the replacement is a kit which is £780 fitted.


edit: Garage is Kwikfit

Dont use Kwikfit, they're not mechanics - they're fitters.

Take it to a proper garage, get a proper diagnosis then buy the part from a scrappy if they cant source it
 
Where u live?

Telford, Shropshire

It is not just one of there little garages that do brakes and tires, it is big service centre that does do engine work and it was their specialist who looked it. You may be right though, trouble is knowing who you can rely on. I can ask about though.

There's plenty of us on here pretty local to you, I'm sure someone will have a recommendation.
 
What is the fault with the car ?

I can get trade prices at Vauxhall if you need a part.

Edit - Read your post above, P1112 can also be the MAF sensor did the garage do any diagnostic on the inlet system ?

On the top of the inlet manifold is a connecting bar that connects the swirl flaps to the actuator. These tend to wear and fall off after a while. Have a look and see if it is off. You might get away with refitting it for a temp fix if it's off.

The inlet is not hard to change just a bit tricky and you need to be careful using a torque wrench as its plastic and can be easily cracked if over tightened.

You can change just the swirl flaps and actuator. If the inlet is ok it can be re-used. Most garages would rather just bolt in a new complete manifold as its a bit less effort.

The tech said he needed to see it because it could be more than one thing. Once he looked at it, he said I would have to replace the whole unit.

I don't think it fully broken as the light only comes on with heavy acceleration and I have been managing for some time.

What is the trade price on these?
 
I will find out Monday.

This is what the Vauxhall TIS says about code P1112 (Known issues). The flaps, Actuator and control link can all be replaced and do not require the inlet manifold to be replaced.

Field Remedy: 2233
Subject: Engine Z22YH - Engine malfunction controllamp illuminates, trouble code P1112 (64) stored
Models: Engines: Option:

Complaint: Engine malfunction controllamp illuminates, trouble code P1112 (64) stored.
Cause: Swirl flaps on the air intake manifold sticks.
Production: Introduction of improved swirl flaps in production as of engine-no.:11674296 (03.07.07).

I had this years ago on a deisel vectra as said above if you take off the engine cover you will see the bar back top of the engine, it connects across all 4 flaps but only 1 is motorised so when the plastic wears it pops off and they stay closed, just change the link if you can get one and try that
 
The Kwik fit giy is either at it or no more of a specialist than I am

You've got some good pointers here for starting checks, other than that take it somewhere reputable

Kwij fit are generally OK for tyres, maybe exhausts and mot's - not much else
 
I would be grateful if anyone has any garages to recommend around Telford.

A colleague recommended someone in Brosley but its a bit out of way. I live in St Georges so Oakengates, Trench etc are ideal. Wellington is fine too as it is well connected.
