Hi all from a happyish newbie.
Just treated myself to a 2.5 V6 Omega (2000) and am I happy or what !
Its a beast.
The problem I have with it is the speedo dies and ABS and Traction lights come on now and again.
After much surfing I think it might be the nearside rear ABS sensor, but it looks fine. I bought a OBD unit after some advice, but this car hasnt got a OBD socket, Its Tech II only I believe.
Car anyone give me some pointers please, or anyone near SLady bitshorpe who can help?
Many Regards to all Omega owners!

Welcome to the forum ... :)
Unfortunately you have classic indications of an ABS ECU failure, 3 fixes available ...
1. New from VX - Exceedingly expensive
2. Existing one repaired - about £130
3. One from a breaker, must be same engine size/type and model IIRC - and is an unknown item .. cost ?? variable ..
I went for option 2 .. used BBA-Reman worth giving them a call 01634 687222 and was very pleased with the results. Others recommend other repairers .. your choice... :)
Removing/replacing the ECU is not "difficult" .. no special tools needed ... but it is "tricky" due to lack of access.
have a read here .. :)

Hi dave, and welcome to OOF!!
Bought my car from a guy in SLady bitshorpe...small world.
Dunno who is close to you, to be honest. Someone will look at this and say "**** is close, will come and have a look"
Hang around, mate!

Wow, thanks for answering folks, did not expect an answer so quick! This forum is the best I've ever been on! :y
Looks like I have been seen coming then. :-[
I love the car and intend to keep it long enough to be a classic, but if the parts to keep it going are going to cost the earth, its a big no no. :'(
I will attempt the repair myself, as I am a techie, and this fault seems like an intermittent electrical connection somewhere.
It can go for hours with no fault shown, and then a little bump can set it off!
If there are any owners near Scunny, or any meets near by I would love to know please.
With great regards and thanks, Dave

Somewhere on the forum is a "dismantled" ABS ECU photograph .. which shows where the "track" on the PCB fails. I believe it requires specialist soldering equipment due to the small size and heat capacity of the the item and its surrounds.
I'm probably talking rubbish .. but it's something like that .. Mark DTM was, I think, the knowledgeable person that explained it.. :)
I think that even he said it was best to have them professionally repaired, although he used someone else than BBA-Reman

worth PM'ing some of the breakers here, but i believe the replacement needs to come from the same engine / transmission

Can you find the picture? As we have most forms of specialist soldering equipment here - if its simply a case of small scale track repair or replacing some of the "hairline" cables, then we may be able to do something here?
Happy to investigate this further with a bit of help from you guys?

Hi Dave
Heres a pic
As you cna see, there are sets of bond wires that link the main conductors in the moulding to the hybrid PCB of the ecu.
As acan possibly just be seen in the pic, where extra amps are flowing they double up the conductors (pretty standard practive) and in this case, its the supply conductors that come adrift.
They whole lot is in a clear resin conformal coating to.

I tried re-working one using our specialist kit here (designed for such jobs) and had no joy.

What was the problem? Soldering to the ceramic board or the resin?
