Omega General Help / Help please! MOT failure - Emissions! and the rest

« on: 28 February 2011, 22:47:04 »

Welcome to one of the most difficult problems with cars...

Just want to say thanks for everyone who has helped me out so far on here.  Invaluable advice and pointers!!

So onto the topic at hand.  Failed MOT today on a few things:
n/s/f Headlamp Insecure, and also kickup goes to o/s (like a french car).  How did this pass last year?! (dodgey dealer) So I need a n/s Headlight cluster, HID maybe?  My headlights don't match at the moment anyway...  :-/
Both rear coil springs incomplete.  (Was at WIM less than a month ago, shame this wasn't spotted...)
Handbrake stuff and reg plate, but quite straight forward I hope.

And of course EMISSIONS failure being the big one....

CO content is excessive at idle (1.32% [norm is 0.5%]) and at fast idle (~2-4x norm)

HC level is fine at both speeds
Lambda value is fine (this is ratio of CO? to O2 -  ?) at both speeds

Recent relevant work so far:
New Coolant Temp Sensor (Today)
Cleaned plenum, throttle, breathers, intake bridge (and what I could of EGR and ICV) (Thursday)
Cleaned MAF - with carb cleaner (Thursday)
New Spark Plugs (Thursday)
New Air filter (Tuesday)
New Fuel Filter (Tuesday)
Injector Cleaner - Redex (Last weekend? and half a tank since)
Other Service items - Oil + filter change etc (Tuesday)
Coolant flush - but prob not adequate (Monday)
Checked injector wiring on fuel rail (Tuesday) [& will post an wiring info if one doesn't exist ]
Tramp attempt to clean inside cylinders by putting in carb cleaner and turning over (without crank sesor) (Wednesday)
Compression Test - results fine, all around 240-250 (December)
Paperclip Test - no codes stored (Tuesday)
Tried to look around for exhaust leaks from engine but didn't find any.
2-4-6 Lambda sensor wire/connection looks dodgey but haven't looked closer yet.


Also went for long run right before test.

I had a smell of fuel recently, I think it was all the time, but it was right from startup.
Sparks looked like they had been running rich before change.  After change and running for the weekend, they had more black that I would have expected in 3 days, so prob still running rich.  I then changed Coolant Sensor, and I thought the fuel smell had mostly gone while I was doing my pre MOT run.

All spark plugs looked fairly similar before and after change.  So I guess this rules out a single chamber problem. (faulty injector etc)  I also guess it's not bank specific...


So that's the situation.  Don't really know how to approach fixing it.

Reluctant to just throw money at it, like changing MAF / Lambda / Cats blindly in the hope of fixing it.
I do have a free retest in 10 days (current MOT expired on sunday though).  And the guy said I can come back and have emissions checked for free, then book resest for everything else if it's all clear.  Nice of him

Since there are 2 lambda sensors, do they only tweak mix on their respective bank?  ie, if it's global overfuelling, unlikely that both would have failed?
I've read somewhere that you can do a voltage test on lamda sensors?  And also a signal response test?  (seeing how voltage varies as you blip throttle)  Can these tests be done on the Omega?  Any one know how exactly??
Also thinking maybe it's best if I try and get some proper diagnosis done??
I feel like emissions is always an abyss of possibilities!!!

So there's my mess.

Hope I've included all info.
Please feel free to make educated suggestions!  Could do with some pointers on where to start, or possible tests I could do etc!!

Thanks in advance!  You're all amazing!!!

Omega General Help / 3.0 L cams in a 2.5 - Advice please :)

« on: 22 February 2011, 12:32:13 »

Hey guys...

So I've heard that putting cams from the 3.0 into the 2.5 gives increased performance.

1) Is this actually true?  And what are you opinions?

2) Will I need to change ECU map etc or any other work besides just changing the cams.


I'm considering this now as I have to prob do:
Cambelt - (No service history and had the car a year already! altho garage who did major work on engine said it looked fine..  it needs to get done ASAP after MOT)
Rocker Cover - Broken round the oil filler hole, currently being bodged with silicone.
So, if I was going to fit different cams, the time would be soon! (AKA at the same time as all the above)

Thanks in advance.

Omega General Help / Coolant Sensor(s) ?

« on: 28 February 2011, 10:22:36 »

Hi

MOT booked today, and still overfuelling I think.  So (after ripping off air intake, plenum, breathers, cleaning MAF etc the other day)  I think it may be the Coolant Temperature Sensor.  i.e. it's running rich because it thinks it's always cold...?  After reading posts and thinking back, it sometimes doesn't start straight up again when hot after long drive (which confirms this for me)

I read on here that there are actually 2 sensors for the 2.0 - one for ECU, one for temp guage on dash. Is this the same on the V6?

I also had a wierd thing going on with my guage...  Sometimes the light would be on, and the temp would flick around, eg from bottom to top!!  then come down again after 2 seconds.
I have recently changed coolant.
It hasn't done this yesterday or the day before.
Could it be poop in coolant that didn't get flushed properly that is cycling round and giving dodgey reading when stuck?  Or more simply a broken sensor?
(If of course there are indeed 2 seperate sensors on the 2.5 L)

Thanks in advance.  Looking to get it sorted as soon as poss today and then put it in for MOT later.  (At least I would then have ruled out some stuff before the emissions test)

Thanks all

Omega General Help / What the hell is this??

« on: 24 February 2011, 01:43:21 »

Hi guys...
Quick question...

Was doing some work on my car today (cleaning air intake / breathers etc) and stumbled across this behind my engine!!
Obviously meant to attach somewhere but the guys who worked on the car right before I got it (mechanics next to dealer) left it loose.  This was a year ago now!  No wonder I've sometimes had a random metallic rattling sound coming through the dash!

(sorry for the picture quality, it was with my phone, which is now several years old!)



Any clues to where this goes? (or what is is?) - I can see one part is attached to the breather system etc, if I remember rightly.  I did this while it was daylight as you can see, and I'm not posting quickly before bed! 
Hopefully I can put it back in the right place tomorrow!

Thanks in advance.

Omega General Help / Snapped airbag connector!! Help please!

« on: 09 February 2011, 15:36:18 »

Hey guys...

Yesterday I fixed the heated seat on pass side.  Today I went to do my drivers seat, and on removing the plugs, I snapped the clip on the yellow airbag connector!
Any tips?  I'm guessing I can't just superglue it?
I'm obviously car-less (barring friends giving me lifts) as I can't plug up the battery again until the airbag is reconnected, otherwise I will get the permanent airbag light on the dash.

Here's a picture of the connector from someone else's thread.  Mine is yellow instead of grey, and has the same purple bit.  It's the clip on the side that has broken off.

http://www.omegaowners.com/forum/YaBB.pl?num=1296819520/0
It's the bottom picture.

Not sure if it's possible to re-wire a new plug.  Perhaps cut the old and solder the wires together to a new one?

Any help greatly appreciated.  Thanks.

Omega General Help / Quick Suspension Purchase question...

« on: 02 February 2011, 15:30:33 »

Hey guys.
My front suspension needs doing before my MOT at begining of March.
Looking at getting stuff ASAP - by tomorrow, and taking down to my mate who has a garage etc.  I've never done suspension before, and he's got the stuff to do tracking and camber too....
That's the plan anyway.   So I have some quotes, and I've read up what I can on the forum.  Please say what you recommend.

The jobs that are "needed" as per Kwit-fit free suspension check (I know, kwik-fit are cowboys...) are:
Front Shocks and n/s wishbone bushes (replace whole arm).  Having done bushes before without a press, I'd rather replace the whole thing!!

Given the prices below etc (which are on trade through a motor factor)  do you suggest I do just the bare min, or both wishbones etc, if so, which ones?  Also should I do springs and droplinks while I'm at it and get the whole lot done....

Shocks - Sachs - £50.99 each
Springs - Sachs - £25.50 each
Wishbone - Qdrive - £36.50 each
Wishbone - "original" (I'm waiting to find out what brand) - £47.95 each
Droplinks - Lemforder - £13.25 each (these are the official ones right?)
Droplinks - Qdrive - £6.50 each

Also quote through unipart: (not trade and don't know brands)
Shocks £50 each
Springs £47 each
Wishbone £48 each "probably Firstline" (not good right?)
Droplinks £16.16 each

All not including VAT of course at 20%


What do you guys think?  opinions?
Thanks in advance

Newbie Welcome Area / Hey guys. (another post called newbie?)

« on: 19 January 2011, 11:20:33 »

Hey everyone.

I've been recommended to join this forum my a friend of mine. (Impact Pete).  I've actually read this forum a few times before and its been a great help when working on my car.  So thank you all!  Hopefully now I can contribute back and get more linked in with you guys!

Mine is a 2.5 V6 CDX Pre-facelift (mini-FL I believe) Saloon from 1999 in red and MANUAL
(I also used to own another pre-FL 2.5 CD saloon, and I'm a big fan of Omegas!)
I've done a few bits of work on both cars, as well as a work on other cars (also own a Polo at the moment).  I don't like paying over the odds for repairs and services and I've got more free time than money! (unemployed at the moment)
Oh and I don't have a garage, only a quiet car park.

Don't really know what else to put on here!  So thanks for all the help so far, and looking forward to being a part of this forum.

Julian
