Very useful thanks.
I have to go to Bicester this afternoon, so I wonder if TB is around and prepared to plug in and give it a once over?
I'll drop him a PM too to see if he is able.
Thanks
Nathan

Question.......did the new codes appear immediately after the work was done or some time after?
The definitions are as follows:
P0170 - Fuel trim malfunction (Bank 1)
P0173 - Fuel trim malfunction (Bank 2)
Now, this can be affected by the exhaust!
Also, worth checking fuel filter, inlet system for airleaks etc.
Did the new codes appear immediately after the work was done or some time after?
I'm not sure, but the new exhaust hasn't been on that long (2 months) so I'd consider "some time after" to be as good as immediate. I don't know how long the error message has been ther because my EML buld went IMMEDIATELY when the exhaust was changed and lambda sensors moved and I only became aware when the "service" light showed for a while.
Now, this can be affected by the exhaust!
Bugger.
Are there any other symptoms or ways of checking?

I don't have the true definition, but I'm told they're to do with fuel trim.
There's a bit of history to this one...
I used to get 0420 & 0430 which was a notification that the difference between the readings at the 1st lambda sensor and the 2nd was not cleaned enough which indicated that the "pre-cats" were a bit tired. This is very common on the 2.6 and 3.2 litre engines.
I then had a stainless (quiet) cat-back exhaust made and whilst they built it thay added 2 new lambda sensor bosses behind the main cats and moved the secondary sensors further back so that both the pre-cat and the main cats were cleaning the air between the two sensors on both sides.
This has cured the 0420 & 0430 codes which is some success, but now I'm getting these two new codes 0170 & 0173. Someone (above) has said that this is to do with lambda sensor or fuel trim issues, and after doing a search on here on "0173" I have seen evidence to confirm, but I'm now a bit lost. :-/

Fuel trim codes are generated when the ECU can't compensate the fuel / air ratio against the readings the Lambdas are giving.
When are the codes generated? Cold start or normal operating temperature?
Best person to speak to would be Kevin Wood.
Thanks Andy; I've sent him a PM, let's see what advice he can add.

No, I had 0420 and 0430 before. That code cleared when I moved the secondary (further back pair) lambda sensors back behind the main cats rather than between the pre-cats and the main cats.
I had to replace one of the lambda sensors as it was rusted into the thread so I just left it in there and cut the wire and put a new one into the new boss behind the main cat when I had the custom "cat-back" exhaust made.

0170 & 0173
I used to get the old chestnut 0420 code and then moved the secondary lambda sensors to behind the main CATs which has resolved that, but now I have the 0170 & 0173.
Why? Are these for the front lambda sensors or something?
What do I try now?

2.5 TD is a good car, but what about a 2.6 with LPG perhaps?
If you're considering a 2.6 in the 1st place then you are looking at a relatively new car, but you're concerned about running costs so be careful of the March 2001 deadline.
Cars registered after March 2001 will soon cost quite a bit more to tax for the road annually.

What is the root cause of the fuse blowing?
Good question; I now have a two level plan of action:
- 1) A load of fuses from Halfrauds in the glove compartment
2) Wait for Weds to work it out and let me know
Quote
Check fuse 15, (feed to instruments) my omega blows this fuse randomly, still trying to find out why.

RAC man: Mmmm, I'm stumped. I’ve checked everything that is in the manual and I've spoken with the Technical Department, but they haven't got any ideas either. My time is up now (1 hour) so I'll have to tow you home.
Me: OK; so you're sure all the fuses are ok then?
RAC Man: Yep they're all fine. That’s what I don't understand. All the earth's and the battery voltages are perfect. All the fuses are intact. Your indicators work, the green lights on the dash come on when the indicators flash; it doesn't make any sense to me.
Me: OK, as long as you're sure it isn't a fuse then I guess I'll have to go online to the omega Owners Forum as a 1st shout and see if they have any ideas. Failing that I'll have to go to a garage. Bugger!
I’ve just been outside to check fuse 15 as per Weds’s advice above^. Bang on! 1st fuse I pulled and it is burnt out.
I suppose I should have checked the fuses myself. At least they were there in 15 minutes and tried their[/i] best; bless them.
Cheers Weds, good man!

It sounds very electrical!
all voltages seemed ok

I was driving along this afternoon and the car just died instantly.
I coasted to a halt and tried to start, but no go.
Symptoms:
RAC came out, tried all fuses in dash and near battery. Retested and reconnected all earths, including those under the battery.
Any ideas?
I coasted to a halt and tried to start, but no go.
Symptoms:
- Dash lights come on when the main beam lights are switched on.
- Indicators work and the little green lights work on the dash when they flash. The same for hazard lights.
- Stereo works as does the colour sat-nav screen.
- When I turn the ignition on there are no dash lights coming on that would normally come on when the ignition is switched on (Ignition, ABS, EML etc.)
- Engine turns, but does not fire (similar to the crank sensor symptoms), but there are no lights on the dash that you'd expect.
