 This question is for one of my 3.2's.  Lumpy tick over, EML on, so with the help of Dr G, the dodgy ECU was swapped from the other 3.2  and vice versa to confirm that a fault is present PO150, O2 sensor had been changed with a new Bosch sensor before the ECU change around. So currently running the 3.2 on a 2.6 ECU and running great...but I've been trying to get the faulty ECU repaired,and have sent it to a couple of companies, who big themselves up, but can't help. So is there any one here that may have had a positive result recently for an engine ECU repair? Also there are a couple of used ones on ebay, but minus the chip and transponder ring, so basically £150's worth of door stop!

I’ve used AP-Reman and www.ecutesting.com, both with success, but for ABS Pump module repairs, not engine ECU. 
As these two pop up in a search, I’m guessing that maybe you’ve enquired with these already though.

Thanks for the heads up, I haven't tried this company, but will fill in their online request form, and see where we go with it. Apparently it's been suggested that I send the ECU directly to Bosch in Germany, but that comes with the risk of it going missing in their system/ language probs. If only the people that are breaking the cars do the job correctly, and remove the relevant parts

I have a 2003 3.2 which about 10 years ago apparantly fried the ECU due to an electrical surge or spike from the battery(?), and I had more lights on the dash than a Christmas tree.
Spoke to a couple of places that repair ECU's (one was in Derby I recollect), and I sent it to them but it was returned as unrepairable.
I decided to take the plunge and bought a used one from Ebay off a Police 3.2, complete with the transponders ring and key fob chips.
A former VX auto electrician with I presume a Tech2 etc reprogrammed it to my own 3.2, retaining my original key fob chips and transponder ring, and it has been fine ever since.
An option to consider if you know anyone with the ability and means to do it...?

Thanks for the info, I'll bear that in mind if the repair option fails, which seems likely at the moment. But the car runs fine on the 2.6 ECU which I bought off a guy on ebay, who sensibly had the chip and transponder with the ECU. But  I'm a bit twitchy on paying another£150 for an ECU on its own from an ebay scrapyard seller so there's no real rush to solve the issue, just trying to avoid the so called repair companies, who make claims that lead no where.

Ideally if you do get a replacement ECU, get the security code with it - that gives options around pairing it to immobiliser.

 I have just sent the faulty Ecu away for an assessment/repair, and also purchased another complete 3.2 Ecu from another reliable contact, so hopefully that will be the problem solved Thanks to all for the advice and interest, and now thinking that I might try and locate a 3.0 Ecu..just in case!

I've yet to see a 2.5/3.0l one fail, although they are ageing a lot now, so who knows. But where do you stop?

Seen a couple of wonky 3.2 ones, in one case defo caused by a shitty charger spiking it.  Seen a couple of 4 pot ones fail as well, can't remember which variant.  Seen a couple of transmission ones fail as well.  But in general, Omega ECUs are pretty bombproof aside from the post 1998 V6 ABS one.

I was surprised that the 3.2 kicked up at 107k, but the other 3.2 running a remap and now showing 251k never misses a beat. However, I agree and that it is where do you stop? and because of the age of the cars, this issue just highlighted that it might be worth putting one in the spares shed, and the 3.0 Ecu's are cheaper, and there seems to be a few more around at the moment. Also my driving days are slowly diminishing, and although I think that I'm still the oldest boy racer in town, my eyesight and creaking joints, tell me I'm not! But keeping the three cars on the road and fighting the EV pressure, is a sort of two fingers up and something I will never do! So I can't really make the cars future proof, but just keep them in use until have to give them up.
