Omega General Help / Re: Elite sunroof opens

« on: 06 April 2009, 13:21:12 »

I had to fix the mower at the weekend!!!

I still cannot see how to get into the mechanism to clean.  I guess I'm missing something simple somewhere.

How do you get 'in' to access the parts?  (I don't have Haynes and find the Vauxhall system not very friendly).

Thanks again, Steve

I was going to have another go at this over the weekend.  Any advice how to get past the palstic (without breaking it) to clean behind?

Cheers

In 5 mins I took off the control knob (5 seconds) and then ....?  I took this photo - what comes off next?  The illuminated part seems securely fixed in place - more help needed I'm afraid. I fiddled to remove the illuminated ring but was afraid of breaking it.

I've done that many times.

I read on here (somewhere) that some parts could e removed and some other part cleaned.  And Iwas looking for guidance on what to remove and what to clean.

I have seen a fix on this forum to clean part of the sunroof pre-selector to stop it spontaneously opening.

Mine eased up a day or so ago and I'd like to fix this.

Could someone direct me to the instructions - thanks

Omega General Help / Re: EML is ON - been using 'Super' fuel

« on: 03 April 2009, 21:39:17 »

Hi Steve,

It's the post-cat Lambda sensor we're talking about moving. At the moment you have one Lambda sensor for mixture control immediately after the exhaust manifold - before any of the cats. That stays where it is.

You have a second lambda sensor for cat monitoring after a small pre-cat in the elbow of the downpipe. They you have the main catalytic converter, and then the rest of the exhaust.

The pre-cat gets tired and causes the P0430 and P0440. What we are proposing is to relocate the monitoring lamdba sensor further back behind the main catalytic converter so it is in cleaner exhaust gas even if the pre-cat is not working.

I have wondered if there's an electronic solution to the problem. It's less simple than it seems because, from what I have seen about cat monitoring systems, they do expect activity from the post-cat lambdas during some parts of their efficiency monitoring cycle. If they just saw no activity at all, they would raise a lambda sensor fault.

Kevin

Thanks for responding so quickly  That is much clearer now (I wasn't adequatley familiar enough with the topology).

So, Marks DTM said it was easy to weld a boss etc - how can this be done (and how much)?  It is not easy for me.

I'll try to make one answer to the comments  from a number of your answers above:

a) for me (I'm an electronics engineer) to drill and tap is a mission - not easy at all  

b) If the exhaust is drilled and tapped after the 2nd cat then this will be next to the exisiting 2nd lambda sensor (if I understand correctly).  So why not just connect the wires from the front lambda sensor in a parallel with the existing one already there behind the second cat?

c) to stop the the EML beign illuminated I want the lambda sensor to be seeing a 'clean' exhaust - don't I?


Thanks for you time

Could I just rewire the front section lambda cable to be in parallel with the rear rear one?  This would be much easier than all that drilling, welding, tapping etc?

Cheers

Pedal trick  - that's a good idea (I feel I should have thought of that - but didn't); got code 0420 this evening - so that is the pre cat isn't it?

The EML light went out yesterday (~1/3 tank gone) BTW.

Omega General Help / EML is ON - been using 'Super' fuel

« on: 09 February 2009, 23:22:48 »

My engine light came on a couple of months ago and the fault was one of the pre-cats (advice taken from on this forum) and reading the code.  I've been fillng up with 'super' fuel - again as the advice from this forum is regarding the benefit of extra detergents in it.

I've put quite a few tankfuls through now and it seems that every time I fill up the EML comes on after a day or so and then goes off  about 1/2 of the way through the tankful.

This is not what I'd expect; I expected that once the cleaning was done and the EML light extinguished then it would remain so.

Not sure if this is relavent but the car feels smoother since the use of the alternative fuel.  I still only get about 22mpg on my 18 mile daily commute of mixed side roads and dual carriageway/motorway.  I'm sure it was nearer 28mpg last summer (maybe just warmer weather)?

Thanks for the input.

I find my Omega is prone to 'tramlining' which is aggrevated by incorrect tyre pressures - this is easy (and cheap) to check for.
