I have a 2006 sri cdti (150) and it has suddenly developed a accelerating probelm.
it starts no problem and idles fine.
but when i set off , it is lacking power accelerating untill the revs slowly reach 2500.
then it picks up.
whilst idling, when you rev it slightly it doesn't want to rev smoothly and feels like it is missing a little.
even when warmed up the initial acceleration is way underpower until it seams , when the turbo kicks in???
not too up on these cdti engines!
any help or ideas would be appreciated, before i take it to the garage to be checked.
thanks

Sounds like an EGR problem from experience with a car with EGR problems. Go to dealer and get the codes read.
|
|
|
Hi,
no codes displayed, the car runs as normal in every other way.
Since been told it is possibly fuel starvation , till the turbo comes in.
blocked fuel filter??
bad fuel??
it all seems to be happening since i filled up at ASDA.
even though i initialy did 130 miles the next day all OK.
I will have to have it looked at over the holidays......thank gooness for the wifes
little matiz to run around in!!!!

is this the eight valve or the sixteen valve engine, if sixteen then the swirl flap acctuator rod comes of, easily seen if you know where to look, but either way it may be a warranty job assuming that you have done less than 60k i know its not what you want to here over the christmas period but traet it as a bonus you can have a few beers lol
|
|
It's the 150PS he says so must be 16v?
|
|
well spotted, i wondered how long it would take to spot my deliberate mistake !!!!!!!
|

|

Hi, thanks for the reply,
it has unfortunatly done 61,500 miles........sods law!!!
i took it for a small run this afternoon and the symbol of the car with the spanner lit up.
i have read the book and this on diesel cars it says is a sign for possibly the fuel filter/water in the filter.....
swirl flap actuator?? can you elabirate on this???? is it something i could check??

You can check the actuator by looking under the plastic engine cover. In the gulley there is the actuator, I've seen one moving under Tech II control, but I guess it would also move if the engine was revved.
If you look closely you should be able to tell if it's broke or not.
Good luck, after mine was fixed I asked how much out of warranty, something like £800 was mentioned...
|
|
as above, just below/behind the glowplugs, steel rod with plastic cups which fit over the balls on the flaps, could even be the egr valve itself maybe worth a call in to the dealers finding what the code is and ask vauxhall for a contribution
|
cheers for the help.
i will have to bite the bullet and take it in.
it ran today but would not pull untill the turbo kicked in over 2000 revs.
then, when the enging/car symbol came on.....it wouldnt pull , even past these revs.
as tho the management was restricting the reving.??
but before this it ran smoothly, but just wouldnt pull in the lower rev range.
time to take it in on saturday..........
|
The turbo will kick in (or should) straight away but as turbos use exhaust gases there is some lag. Modern diesels with turbos have little lag.
If the engine management light is on then the car is probably in limp home mode.
What does the DPF warning look like on a Vauxhall 1.9 diesel? Could it be the DPF?
|
|
you dont get a seperate light for dpf the glowplug light should flash to warn you that the dpf needs a regeneration assuming that the latest software has been loaded into the engine ecu
|
once again , thanks for the advice.
the engine warning light that came on, was the symbol of the car with the spanner.
This according to the handbook , (for diesel cars) is a possible sign of water present in the fuel filter .so i am going to change the filter first thing on saturday.
for a vauxhall one at £21-00 , it is the first point of call i think.
I am not too sure if this would cause the management system to reduce the preformance of the engine...??
And i will also chech out the swirl acctuator....
merry xmas day!!!
regards

basically its in limp mode and the light is telling you this is the case just incase you had not noticed, if there is water in the filter "unlikely" you just need to drain it "there is a drain tap on the bottom of the filter, you will struggle to change the filter anyway" drain the filter a bit not totally empty it, save your money, spend it on a diagnostic check and ask them for the codes, but i suspect that it will either be a egr fault or the flaps/swirl fault ask the dealers to do a sps update "ecu update" and ask for a forced regen of the dpf, Regards TB

Hi,
just had the engine cover off.
and you were right topbloke.....
the swirl flap bar with the black caps on is not connected to 3 of the holes.
it looks loose , except for the first 1 or 2 on the passenger side...
thanks for the advice......i will have to see if vauxhall will be willing to stump up some of the cost , as it is only 1,500miles out of warrante......who knows,
can only try, if not i will try and source out another garage.
have one or two good alternatives localy.
thanks for all your help

hi again,
with a bit more digging and looking closer......
the swirl valve bar across the engine was disconnected from one of the points.
anjd this point was moving when reving and engine turned off....
but after re connecting this, the bar doesn't move when engine reved or turned off
so as you advised.. i think the swirl vvs are stuck......
will have to get prices tomorrow if possible.
thanks again....

the flaps are controled by a motor slung under the manifold not surprised you cant move it

hello have been reading your posts about lacking acceleration on 1.9cdti. and the swirl valve being loose . mine is the same , what was the outcome do you know how much to fix the problem . my car still drives fine when warm though. thanks

Hello have been reading your posts on 1.9cdti lacking acceleration.
I have recently brough one and it does the same only when cold though then the car and spanner light goes off and its fine . I looked and the swirl flap rod is completly off , i(t is the one on top of the inlet?) with 4 black plugs . do you know if it just pushes back in or is it a costly repair Thanks Rob
My car is an 04 sri 150 cdti only 55,000 on clock

the rods jump of for two reasons either excessive wear (plastic on plastic plus general debris that floating about) or because the swirl flaps get all gummed up either way its a new manifold, if its a 150 then it will be 16v, the 8v has no swirl, Regards TB

not that i am aware of, most of them are within warranty which yours is unless its done more than 60k, ? somebody may be doing a fix for them perhaps, i should get my finger out and corner the market with a repair kit lol

hello sorry to keep asking questions but you seem well informed .
So is my car still in warranty even though it is over 3 years old i thought it was 3 years or 60,000
cheers rob

Your warranty should run out in 2009 according the year you put in the subject line !
Edited by Pugugly on 03/01/2009 at 22:28

hello.
have got a price to fix problem - new manifold and vauxhall said do cambelt at same time £879 inc vat NICE
|
Hi,
thought i would let you know, i have had mine fixed now.
got it back yesterday. new inlet manifold (wich incorporates the swirl vv's etc)
actuator and bots and bobs.
The EGR vv needed cleaning aswell (so the said) cause they couldn't get it running properly after the new inlet manifold/actuator was replaced.
cost was £680-00 ouch!!!
manfiold £200 actuator motor £140 labour 3.5h £260 and the bits and bobs!!
OH and plus the £75 diagnostic .
Not a nice xmas present!
Running like new again..........
Not too sure SPILS if you need a cam belt yet..... advised me, to do at 100,000mls / 10yr
The bar on the top of the block behind the glow plugs , can be popped back onto the plastic posts of the swirl vv's . As i had to do this with mine before it was fixed.Mine had come off.
They had one in for the same fault as mine when i picked mine up......
08 Vectra 10,000 miles.........showed me the manifold.....caked up with soot and carp
The reason they gave me for this happening was, it has been driven too lightly!! around town all it's life....
The technician's advice was to make sure I give it , in his words.... A GOOD THRASHING
Don't drive it softly all the time. give it a good going through the rev range!
This stops it sooting up and gives it a clean out.......
Looking at this manifold, I couldn't see why they couldn't clean it, and just replace the actuator/motor. It only gets sooted up and all the swirl flaps stick. He demonstrated how it all worked with this one and they were working ......just needed a good clean.
But i bet they replaced the manifold.
But basicaly.......cannot gaurantee it will not happen again......
Hope you get it sorted......
