dave the builder: Thank you! for your video link and advice. Please may I ask.... the letters MAF have been used in a response to me.  Do you know (or anyone) what MAF is please? Many thanks!!

VXL V6: Thank you so much for explaining to me how to remover the EGR and clean it up. Much easier now with your explanation.
Just a quickie question: You say the flaps may be damaged. So if I take out the EGR to clean it and then find the flaps damaged, can I put it back in while I order and wait for the replacement to arrive (as I don't have another car)? And if the Vectra B 2.0 DTi is same'ish as my engine? then can I find a book or download of my Vectra B 2.0 DTi (or my engine) with explanations on how to fix (like a workshop Haynes book)? I have looked but cannot find.
As I have a PO400 code that means I have a vacuum issue - so that is the EGR yes? So could that just be a withered seal on the EGR maybe? Sorry if it is a daft question
Thank you so much for your kind help.
Broomies Mate: Thank you for your reply. Sadly the breakdown services do not work as they do in the UK. Breakdown in the UK is wonderful compared to here in France which is next to useless. All breakdown do here, apart from helping with a flat tyre, lack of fuel or other very simple issues like that, all they will do is arrive, suck air in through teeth and then tow the vehicle to the nearest garage. Not even to your home even if desperately requested. They just don't try to fix on the side of the road like they do in the UK.  So no good turning to breakdown for help. Breakdown in the UK is fantastic compared to France.....
Andy B: Thank you for posting.  Please may I ask (and please don't laugh at me ) but what is MAF?
Thank you so much for your kind help.
Thank you everyone! What a great Forun and soooo much better than any mechanics I found here in SW France.who really don't seem to know my engine or car. I am sure that is not true for all of them but sadly it is for the ones I have found.
I am so grateful for all the help I receive on this.
Once I have sorted this I will definitely post a report on what happened, how fixed etc....as this may be useful for anyone else in the future.  I also hope all this advice you kind people are offering me will be useful to read for others with same problems.

Thank you everyone for all your very kind replies and assistance. Please accept my apologies for the delay in my reply... (had other problems to deal with called life .
Entwood:  thank you for your description of how the crank sensor works. My partner read your explanation, as did I, but even so my partner understood it (I didn't ) and so, in turn, explained it to me. It all makes sense now and why car is exhibiting such symptoms. It is good to not only know how to fix it but also to understand it. I am learning loads thank you as is my partner.
dave the builder:  Thank you for your help and your video on cleaning the EGR valve. Both my partner and I have watched it. My partner is saying that our car, Omega B 2.2 DTI CDX 2002, is slightly more complicated than the one in the video the Vectra C. Is our engine the same as the Vectra C? Because on ours we have air-con pipes which we would need to remove (as well as some other pipes which partner says he doesn't know what they are). We cannot see our EGR clearly so are not sure which model EGR we have but assume it is a vacuum one?  Would you or anyone know which model engine we have please? Would the VIN number help? I can post that here (is that allowed on the forum?). Is it easier for us to swop the EGR for another one rather than clean it? We were told by a mechanic (who would charge us! so he has a vested interest) that we should NOT touch the EGR (again he quoted thousands of pounds job etc...) as we could completely mess up the engine!
Last but not least thank you ever so much Doctor Gollum for all your help, advice and involvement with this.... will be so pleased once we have managed to sort it. 
I have located the crank sensor and ordered it - 31 euros Bosch. Cannot order a replacement EGR till I am sure which one it is or whether that is daft and should simply clean it.  Mechanic said if it is playing up then better to swop for a new one as it means that the EGR is faulty.....
Really grateful to be able to turn to you guys here on this forum for help and opinion! Thank you all!

Doctor Gollum, Thank you for your reply. Will check out Ebay for the Haynes Manual for Vectra C.
I have located a new Bosch crank sensor for 31 euros. So will replace that unit. The crank sensor currently in car is covered in oil. So I cant see much. I believe the oil is coming from the oil filtre. So I will change the sensor, hopefully it will make the car behave better, then change the oil and the oil filter.  What do you think? Does all that sound correct to you? Can the oil on the sensor stop it from working properly or is that daft? Please let me know what you think.
Also, please may I ask? Can you explain to me how the crank sensor works? I have no idea apart from it is a cable with a three-holed plug that plugs in (that is the wire, the crank sensor cable, that he fiddled with before and it cured it for a long but temporary fix). Would love to understand how it works and causes the EML to come on causing loss of power and stall the engine and also cause the rev counter to misfunction..... Could you, or anyone else, please explain that to me?
Thank you Doctor Gollum, really appreciate your help. Loving my Omega...

Doctor Gollum:  Thank you so much for your kind reply. Yes the original registration plate was V002 - how did you know?!!! . Any idea please where I can get hold of an early Vectra C manual? If it is the loom as well, do you mean by the loom all the wiring that connects into the engine block? How on earth could I find which wire is playing up in that case? Worried!!!

dave the builder : Thanking you too for your kind reply. I am sorry but I have no idea whether my EGR is electric or vac type.  I have asked a friendly English mechanic about 3 weeks ago but as yet have had no reply from him. How can I find out? If I wanted or needed to change the EGR then I would need to know this to get the correct model. I do know that about 2 years ago the friendly English mechanic put the car on his diagnostic computer (not a very sophisticated one maybe), the fault came back as a vacuum leak. Does that help me to find out? Why would there be a leak? Would that be a hole in the EGR or a rubber perished maybe?
I only have one car (my omega which I love) and in the middle of countryside here in France. No one here to help me (except you guys .  So, how difficult is it to remove the EGR and then to at least have a look, hopefully try to clean it up, and then replace it - as I can't be stuck without a car and no transport.  Are there any descriptions and maybe with photos on here on how to do this on my car please? Or can you explain please?
Local garage is friendly but no use as telling me they need to change the electric diesel pump and 2000 euros please and diesel specialist wants me to leave an open cheque. So I have to sort this myself - well my partner really who has some ideas and will do the actual mechanic stuff - but I type quicker than him .
Thanking you both dave the builder and Doctor Gollum

I have been searching all day for this fault.  Now on the forum I find it may be the crank sensor and also how to replace/fix it!
Found here:
http://www.omegaowners.com/forum/index.php?topic=99451.0
and how to fix it here:
http://www.omegaowners.com/forum/index.php?topic=90640.msg1155585#msg1155585
All seems to be correct as the symptoms I had before starting 2 years ago were EML suddenly and loss of power. I was staying at a friend's house so her mechanic came and said he fixed it, charged me 75 euros, had not fixed it. So I got back home 90kms and my partner next day put his hand in blindly (where the mechanic had told me the fault lay) and fiddled with what he thinks is the crank sensor cable. Anyhow his blind fiddling with the cable fixed it for a good long while. Then it started to play up again finally leading to the problems described above in first post above here.
Local garage gave me the following codes:
P1335, P1125, P1631, P0725, P0400.
Local garage then sent me to a diesel specialist who wanted to charge me 58 euros for the computer code check, and a further 81 euros per hour till it was fixed. Diesel specialist said it could  take several days till it was fixed and could not give me a quote as he may need to order parts and see if it fixed it or not, and if not keep ordering parts till it was fixed. Hence 2000 euros bill plus possible.
I have since reading all this on the forum found the crankshaft sensor to buy online (27 euros plus 11 euros delivery charges coming from UK to France) and using the description of replacement here: http://www.omegaowners.com/forum/index.php?topic=90640.msg1155585#msg1155585
can try to fix it (a royal we - my partner will have to try lol..).
But this description where to find the crankshaft sensor etc....will this be good for my Omega 2.2 DTI CDX year 2002 (or 1999 as explained above)?
Dont have and can't find a manual for this car - if could then my partner would have looked for himself to find the issue.
Hoping you guys can advise me?
Does my EGR valve also need replacing?
Thank you all for reading. I love my Omega!

Omega General Help / Is the problem my EGR Valve? or something else?

« on: 28 June 2020, 13:53:38 »

I have a Vauxhall Omega 2.2 DTI CDX year 2002 Saloon (or could be 1999 as the first reg on logbook says april 2002 but the original reg starts with a V so could be 1999 showroom then first reg in 2002 private plates?).
Anyway, I hope you guys can help me please?
The symptoms: loss of power when driving/ going uphill, EML comes on and off, revs counter drops to zero for a few seconds but still drives, then comes back on just like EML going on and off, sometimes engine cuts out completely like a stall (usually at the worst place on the road ), leave it switched off for a few minutes then restart and all okay till next time some kms down the road. Seems to drive much better when cooler weather but when hot weather (30C or over for example) it is much much worse. When I stop if it has been playing up then sometimes white/blueish smoke coming out of the exhaust. Do I need to change my EGR valve? if yes, which one is it as I see many models of EGR valve on car parts sites for my car. How can I know which one to order please?
Please forgive my maybe amateurish description as I am not a knowledgeable mechanic but the local garage wants to charge me 2000 euros to fix it! (maybe they see a woman and assume stuff? or maybe, as I am in France, they see an English woman which is even worse!).... So I thought the best thing is to come and ask you guys as you have always been so helpful and knowledgeable in the past - help please!!!! I love my Omega!

Omega General Help / Re: Oil leak

« on: 14 August 2019, 20:39:05 »

Thank you ever so much Addy and First Boy for your replies. So anyone have any ideas where this oil leak is coming from? Also have to add that it only has 3 glow plugs instead of 4. But always started before no problem and not cold weather. Plus have some (not a lot) white smoke when starting followed by a little black smoke and then gone - no smoke. Can it be dirty injectors causing the smoke when starting? Should I pour in injector cleaning fluid? Thanks for all your advice with this. This is such a great and friendly forum site

Omega General Help / Oil leak

« on: 14 August 2019, 16:41:35 »

Hi guys, I have a 2002 Omega diesel, 2.2L manual saloon CDX model. My Omega has been difficult starting for the past month. Last month I topped up my oil. Computer has been saying check oil level which I finally did today. I found oil level was down to minimum which means around one litre of oil has gone in past month (i dont do much distance driving). When I opened bonnet today to check oil I saw there is an oil leak on left hand side of engine block. From where could this be coming? The oil pump? Please help? Thanking you all.....

Doctor Gollum  Thank you!!!!  I have found it the manual online free download! So now I have the Vectra 02 to 05 owners workshop manual for the engine of my car and the Haynes service and repair manual 94 to 99 (free download) for all the other stuff! Absolutely brilliant!  Thank you so much Doctor Gollum for all your help and special thanks also to Chazza12 and everyone else whose names not mentioned here on this post but who kindly gave also your kind assistance to me.

Doctor Gollum Thank you very much for your reply explaining all that to me. I understand now why that link was removed. Great and thanks for explaining. The O2 to 05 Vectra workshop manual will be good for my Omega engine which is great. Where on earth can I find please a manual for the rest of my Omega though as you said I need one for the rest of it. I have looked online and cant find one anywhere. Do you have any ideas please? Also my car is now driving fine without me having touched the swirl valves. Go figure?
Why on earth it would suddenly be okay I have absolutely no idea!! Can the swirl valves have just rid themselves of the crud that was on them? Any ideas? Thank you so much for all your help very gratefully received...Oh by the way Doctor Gollum and everyone I just came on to this forum and saw that my above post which I wrote and thought I had posted had not in fact be posted due to the fact that my session had time expired...I didnt realise this then but luckily I kept a copy of what I posted so was able to do a copy and post of this so didnt need to retype it all. But wanted to explain why so long before my reply - thanks again Doctor Gollum.

Since my last post of a couple of minutes ago I have searched Mr Google. Ended up in ebay. Looking I can see that there are lots of Workshop manuals for the Vectra including DTI 2.2cc for the years 2002 to 2005 but not for 1999 to 2002 with DTI 2.2cc. The only thing I can find for 99 to 02 is the service and repair (which you kindly sent me in links) but really I prefer the workshop manual. So will the 02 to 05 workshop manual be okay for my DTI 2.2cc Omega year 2001?
Another quick question is this and again I apologise up front for the perhaps stupidity of my question. On the back of the vehicle and its log book it says it is a DTI. However today I saw on the drivers door internal that it also says CDX. Does this mean that my Omega is really a CDTI or just a DTI or what does CDX mean please? Thank you all for your help.

Thank you ever so much for your helpful replies. Firstly I need to apologise for not replying till now. I havent been on the site due to too much to do with other stuff and not enough time. I have looked at the links and thanks again for all of that. First question to Chazza12 is why was the link you sent removed by Admin please? I am asking as I would hate to do something wrong on the site inadvertently through sheer ignorance of any rules here so any explanation would be great to let me know so I dont make any mistakes myself. As for the other links, I have looked at previous manuals Haynes now on line through your links and found one which is 99 to 02 for the Vectra including diesel 2.2cc. However this is the repair and maintenance manual. What I am really after is a workshop manual for my vehicle so if there is a workshop manual for a Vectra that will be good for my Omega 2.2cc DTI year 2001 then that would be fantastic. Anyone know please. I am happy to pay for a manual or download or if anyone has one they dont want and would like to sell?  Just to add here....suddenly my Omega is not playing up. I have done nothing to it since I last wrote on here. But out of the blue it is driving fine. It is crazy I know but that is what is happening. The only difference that although very wet due to lots of rain the weather has warmed up a couple of degrees. Can the swirl valves be affected by the temperature? I realise this may be a very silly question so please dont all laugh at me at once but I cannot come up with anything else that has changed to make it drive fine now? Thank you to every one - you have all be so helpful and I love this forum very much. A great place to turn for guidance and advice and a great community spirit of helping out. Thank you!!

Chazza12 Thanks ever so much for the link to the Vectra Manual. Probably a silly question this for you but this is for a Vectra 2005 to 2008.  My Omega is 2001. Will it still be okay for my vehicle? Thanks ever so much for letting me know.

Thank you all again for your replies. Yes I have read and understood all the replies and checked out the links to you tube and other link to relevant stuff on this site posted last March 2017. I didnt know that the Vectra manual will cover my car engine. That is great to know. I want to get the manual before I do anything. Is this like a proper workshop manual? Where can I obtain it buy it? That would be so great to have the manual. Please if anyone knows where I can buy this please let me know or download it please? I will certainly get stuck in and have no objection to that but wanted to explain that I am pretty ignorant but learning....thank you all so much. Thanks for answering my questions too as I have a much better understanding now of what is going on. Ignorance may be bliss but learning is much more exciting and useful!!
