Just bought a T reg Omega 2.0 16v GLS, while driving back home the speedo stopped working. The rev counter still works though. As this is my 1st Omega could any give me any advice on how I could solve this?
Thanks.

does the abs light come on?
does abs light come on with ignition?
tried pressing firmly on tacho to see if dash seats better.
-
Yeah ABS light comes on when ignition is first switched on. Tired pressing on firmly still doesn't move.
Thanks

Is the last letter of you VIN a W or X?
-
Its W
-
1998 model then.
These seem prone to ABS ECU failure.
When speedo not working, does the fuel computer still read plausible figures?
-
ABS sensors or ABS Ecu problem..

fast admin :y

its a 99 version prefacelift. It doesn't have a fuel computer fitted.

Its a 1998 car though. Not that it matters, all post 1998 cars seem prone.
One other system on your car I can think of that takes a speed signal is the radio (no servotronic steering on 4 pot, no FC on GLS). Does the volume increase with speed?
-
The radio doesn't work because it needs de-coding. So if it is the abs sensors do I need to replace them all?

The fact that the ABS light isn't on pretty much rules out the sensors.
Are you based near me or Marks_DTM_Calib who are able to plug Tech2 in and try to work out what is going on.
Its possible the instrument panel has failed, but more likely its the ABS ECU :'(
-
Bugger that he'd just bought it and was driving home for the first time though :-[
Hope you get it sorted mate :y
p.s. these boys are good!
-
Sometimes, rarely, Abs sensors cant read..Or if theres an electrical problem..
if Abs ECU is faulty it can be repaired..
-
So does that mean I need a new ECU? I live in the north west of England. Willing to travel
Thanks

Whereabouts in the North West are you? There are a couple of excellent Vauxhall independants in the north west, one of them might be near to you and able to diagnose for you.
-
Nearest member to you with Tech2 is likely to be Marks_DTM in Nottingham, which is probably a bloody long way :(
If you can find someone local to you who knows how to properly diagnose what the computer is telling them, that may be better option.
-
You can send the ABS-ECU to BBA Reman and they will test and repair if required .. 5 day turn-a-round and I was well impressed.
Downside to this is... it's a sod to get at and you have no car for a week .. :(
-
Is the ABS-ECU just part of the ECU? How much am I looking at if I send it to BBA Reman?
Thanks for the help
-
miggy has numerous ECU's (Electronic Control Units) all over the place ..:(
Give BBA-Reman a ring on

For my rebuild of ABS-ECU it was £120 I think on a 5 day turn around ... I was VERY impressed with the service.
I have no link to them other than a very satisfied customer...

if there's any sort of trip computer, can you get an average speed reading?
Does the odometer (mileometer) still add mileage when you drive??
I've had 2 V6 Omega speedos fail on me, one pre-face lift, one Mini face lift, both failed not because of the sensors or the ABS-ECU , but because a component in the driver circuit for the Speedo itself failed...
solution in that instance is to get a new speedo (early cars) or get a new instrument cluster (later cars , of which your is one.. I think)
get one from a scrappy , or fleabay first before getting a new replacement to test the theory...
(or of course, repair the original if you can be bothered and have the skills.. ) I couldn't be arsed, so just changed it out for another...
