Title: Intermittent ABS light
Post by: alexw80 on 01 July 2013, 17:04:33

Been getting an intermittent ABS light on my dash now for some time. First started a few years ago, but only showed up once every 6 months or so. Now it's becoming slightly more regular. Switch the car off then back on again and it clears, so thinking it might just be a connection somewhere that's causing it. Anyone know what it might be and how to fix it?

More than likely an Abs sensor breaking down,it'll need to go on a code reader though to be sure which one is playing up :y

Does it ever take out the speedometer with it?

If so, it might be the ECU failing, which is probably the most common ABS fault we see with the Omega.

Op didn't mention any other "happenings" which is why I went the sensor route :y

IMO sensor issue, although symptoms started like that when the abs ecu packed up on the old Elite Estate.  A visit to a Tech2 should confirm ;)

No speedo issue, not at the moment anyway.

If it is the ABS sensor breaking down how easy is it to replace and roughly what would it cost?

There are four sensors,one for each wheel,quite easy to change but you need Tech2 or equivalent to diagnose which sensor(or anything else) is flagging the fault

Yes, not worth touching anything until you've been able to read the codes from the ABS ECU to find out what it's not happy about. :y

Got a mate of mine who's got a diagnostic system, will see if he's got a spare few mins to plug it in and see what's what.

I had exactly the same intermittent ABS light problem on my old 2.0 estate.  Someone suggested replacing the brake light switch which I did (what an awkward contortionist job it was) and the ABS light never came on again so could be worth trying.

Rather than "hopefully" replacing parts, why not get the codes read to pinpoint the fault :y
