hi all , driving home tonight the speedo on our facelift v6 just stopped, then the TC ,ABS warning lights come on , after a couple of miles it cleared itself, speedo back to normal warning lights off ......... then back on again . any ideas ? cheers all.

Very well known problem .. the ABS electronics need repairing ... couple of places do it

BBA-Reman being one .. around £130 when I had mine done 7 years ago ..

Yep abs ecu b*ggered, classic symptoms I'm afraid.

As said either go for repaired one, or good one from a breaker (needs to be same year/spec motor ideally or a chat with Tech2 required) - don't go to Vx (last I heard was £700 for part!)

Damn awkward job to swap it over due to lack of space, but diy doable (many on here have swapped them, myself included)
Howto in Maintenance section.

Before condemming it, what age is car?

If its pre 1998, its probably more likely to be sensor or reluctor ring (latter is rare on Omega). If someone nearby has a code reader capable of reading abs unit, worth checking whats stored.

OP clearly states "facelift V6"

Specsavers. I too should look like a speccy foreeyes. But thats gay

Still worth popping on a local member's code reader.  Pissing in the wind though, but this may just be that one that isn't the ECU.

thanks all for the info , going to check out the rear sensors first at the weekend , then see what happens , car is too good to throw away , looks great , sounds lovely,drives great , but dont wanna spend loads on it , got good history with it aswell , so i wanna keep it tho wife wants something elso ...... not on my watch , cheers all

If you don't want to spend too much on it get a second hand ECU which will cost about £35

well the problem didnt get looked into over the weekend as iam now on crutches due to knee injury , but everything is now back to normal speedo, tc, abs ,i know its gonna need looking at and will sort it , but thanks for all the advice .

If its intermittent it points even more at the ECU ... the "fault" seems to be temperature related, and I mean the temp of the ECU internals ..

On mine it started as; it would work for 10 minutes, then fail for an hour then start working again.
Slowly and surely it got worse, work for 5 minutes, not work for a couple of hours - and as most trips are less than 2 hours it was, effectively, not working

The failure is a detached bondwire fom the ECU housing to the hybrid PCB and hence why they can be intermittent.

I always use this company:

As they are cheaper but the service and quality is equaly as good (lifetime warranty on the repair to)
