Hands up...I'm guilty of not visiting for some time, mainly because my 2.2 facelift Meega has been fine and I've had no problems. I have now.

It's a Sept 200 (X Reg) 2.2 CD Auto (Silver)

After having the exhaust centre section (yes, the one with the CAT) replaced last week, I now have the engine management light permanently on and low power, almost feels like a blockage but it doesn't clear when I rev. The professional supply & fitting company (a National company) claim they have no idea why the light is on but have told me it should clear in a week or two?

Any ideas what the cause may be?

PS. The CAT section was replaced not because the CAT was duff but because there was a leak around the small flexible section near the joint with the second half of the system.

Many thanks for reading this and a bigger thanks if you have any possible suggestions re the cause.

hmmm, why didn't they just change flexi bit, rather than whole lot?

Many thanks for the response. Why didn't they change the 'flexi' section? Mr Fitter said it can't be changed - has to be the whole section?? cost of £300

Thanks for the info re the fault codes - the exhaust centre have no code reading equipment so I suppose I'll have to take it to a Vauxhall dealership to find out , then take it back to the exhaust centre to prove my point.....I've sorta totally lost any confidence in their 'repair' process- the best bit is that they also broke an exhaust stud from the downpipe and are reluctant to repair or replace it saying that three bolts will do the job just as well. All in all it was a peach of a job...not!!


Cheers again

Go back and tell them to replace the broken stud as 3 will not do just as well.You should be able to do a paper clip test to find out why the eml is on, if they have buggerd up the sensor in the exshust then they should replace that as well.They broke they fix it.  

[bigall]

paper clip test cannot be done on 2.2 requires a tech2. See if you can find a decent auto electrician who has one or at least the capability of reading codes from your car. Vxall prices are steep. Fight for that bolt replacement as ffcgary1 said they broke it they fixed it. The flexi joint can be changed - mine was at a cost of £90

If you need Tech2 work, I'm not too far, and much cheaper than dealer. Or try Marks_DTM in Nottingham after the weekend, possibly even closer?

...that is very interesting as I had my exhaust starting to blow around the flexie. Tried to get just the flexie but could not source one, so where did you get yours from? At the moment I had welded a flexie off a VW Golf, seems to do the job, but would like to complete the job properly.

Any decent garage/works would replace any broken stud or repair damage. Problem is not many owners see the overall bodes done and they get away with it.

With the light coming on I would think the sensor has been damaged either when they replaced the flexie or the wires are damaged.

my flexi was suppled and fitted by an exhaust and cat fitter in Ormskirk Lancs.

Plenty of flexi suppliers on net . This looks useful http://www.camskill.co.uk/products.php?plid=m15b409s1411p0

Contact  numbers on website . and nearly in Scotland

note that flexi replacement is determined bythe state of the exhaust each side of the flexi - need something to weld to.

Thank you all for your support and advice.
I shall be booking the car back in for remedial work, ie new bolt (they claim they will have to replace the mainfold!!!  but my sympathy level is low to non existant right now) and to sort out the engine management light that is now permamnently on resulting in my Meega running with greatly reduced power.

When I left hem last week they suggested that I drive the car for a week or two and see if it settles down (ie, the engine management light goes off again) but it seems clear this is not going to happen. I have done over 600 miles in the last week and the car sound terrible, especially when started from cold, has no power and frankly I just don't want to drive it whilst it is in this sorry state. I will tell the 'exhaust specialist' who did the job all about the lambda sensor codes, possible wires shorting etc and leave it for them to sort out. However, I have the feeling that they will do all they possibly can to 'cover their tracks' and I have concerns that they may simply take out the EM warning lamp....or am I being a pessimist here?

I'll post an update as things develop for the benefit of any other member who may have similar problems.

Chin up mate, if it's a national chain they have a responsibility to make sure the work is carried out correctly. I know you can sometimes feel a bit of a twonk going back time and time again but keep going back until they have sorted it! If you've got concerns about their work, stand, wait and watch them do it right.

The car came out of the factory with four studs for a reason, it should leave their garage with four. Not many things are over-engineered these days! Your hard earned money, your car, don't let them bodge it. Often think it would be nice to have the facilities, time and expertise to do yourself but alas, is not always the case.

Call me optimistic but I don't think there's too many large garages that would take that much of a risk by completely screwing up the job after a customer has highlighted problems, with the increasing threat of bad press and compensation culture!?!

Rant over

Hi Davladd22, many thanks for the supportive comments. I have even considered having a tech 2 diagnostic done to tell the exhaust specialsts what is wrong but Vauxhall main dealer wants £70 to plug it in and tell me the fault code. My plan is to simply book the car back in for the stud and engine light to be sorted out. I'll keep you posted.

My Meega is feeling real poorly right now.....

A bit of an update on the situation - having needed the car lately I wanted to get some idea of the fault codes causing the EM lighrt to stay on (before I take it back to the exhaust centre who caused the light to come on) I have now purchased an OBD2 reader that gives me the following five fault codes (yes, five)

130 = O2 sensor circuit malfunction (bank 1 sensor 1)
135 = O2 sensor hester circuit malfunction (bank 1 sensor 1)
170 = Fuel trim malfunction (bank 10
500 = Vehicle Speed sensor malfunction
1405 =  DPFE sensor upstream Hose off or plugged.

I understand that fault codes 130 and 135 will be directly related to the work they carried out (cat section of exhaust replaced and both O2 sensors had to be removed and placed in new exhaust) but I'm not sure how the others would be related unless wiring has been fouled during the exhaust adjustments. Any ideas wouyld be very welcome as I expect to have denials and a battle of words at the exhaust centrewhen I take my Meega back.

By the way, the car still has the EM light on - it has been on permanently since they changed the exhaust (never been on before in the 10 months I've owned the car) and it runs with a noticeable loss of power...when I press the accelerator very little happens unless you floor it and even then it's reluctant.

Does it start first time (hot or cold)?

[TheBoy]

i'm guessing they have damaged wiring to lamda or sensor itself.  the trim is related.

other may disappear when lamda fixed

Hi, thanks for reading my blurb...yes almost always.....say 9 out of 10 times.

I shall be booking it in again tomorrow - I needed to know what fault code(s) were displayed before they have it back.....just in case they try to fob me off again. call me cup half full but......
