mmmm decision time ...  a used hub with ABS sensor will be £25-£30 and will require a geo setup after (£90) as well as being an unknown in terms of bearing condition etc etc.

A new ABS sensor from "reputable" vauxhall sources is around £80,

http://www.vauxhallsuperstore.co.uk/product/Sensor_90509421

a cheaper source http://www.genuinepartsearch.co.uk/ is £55 but I've never heard of them so an unknown in terms of quality and genuineness....

methinks a call to the stealers tomorrow and see what they say ...

[TheBoy]

Or see if one of the breakers can get sensor off in one piece?  Foreskin earwarmers are more likely, but you may be lucky?

I've stuck a request in the wanted section .. have to see what comes up in a day or so .. otherwise its a visit to the stealers methinks ...

Hi Entwood, sorry fault is not cured. My first Omega ABS fault I assumed was ECU, bought used ABS.ECU unit (£150) from Steve Brown, fitted it Haynes, involving unscrewing all hydraulic pipes, no cure. So removed ABS.ECU, returned for refund, refitted original. Replaced NS front sensor by replacing hub, no change. In despair, looke at rear sensors, they were OK. Then spotted crack in NS rear eluctor ring, allowing it to slide along drive shaft. Glued ring to shaft, fault cured. Pic follows.

On a Citroen CX, my ABS fault was a frayed front sensor cable. On a Senator I had a rear sensor fail. On older cars ABS is a mixed blessing.

Here's the ring:

Worth checking, but yet to see a failed ABS reluctor ring on an Omega.

Now Rovers....  ....well, its finding one that doesn't have a failed ring!

Incidentally, normally when the ring splits, even if you can secure it, the ECU often gets grumpy with the inconsistent signal it gets, which has 2 possible outcomes - ABS light on and ABS disabled (the better result), or the ABS mis-detetcting lockup under any braking, losing all braking to that wheel (surprisingly scary the first couple of times it happens )

[terry paget]

Not tempted to use the socket method to carefully record current camber setting; then fit a used hub and sensor assembly and see if it cures the fault? If it does then carefully set the camber with the socket method. If not, refit the original hub and think again.

[Entwood]

Thought about that .. but with the sensor showing infinite ohms .. open circuit from the socket itself I doubt it can be anything else .. so its actually cheaper to fit a new sensor than to go used hub + geo ... so unless a breaker comes up with just a sensor .....

[/quote]Mine was fine with ring glued in place. A year later in an icy snap I put some typemetal pigs in the boot to improve traction, filled up with fuel, drove off garage forecourt and both rear springs broke, damaging both driveshaft gaiters. I then changed both springs and driveshafts, thus replacing split reluctor ring.

I agree fault must be in n/s front sensor. Could be in sensor itself, more likely to be a frayed cable, on a front wheel sensor subject to constant flexing. It's worth slicing open the cable and checking continuity near the sensor by sticking needles through the insulation of both leads. If you have continuity, the break is between there and the socket. Locate it, repair it, and job is done. I did that on my Citroen.

[Entwood]

Ordered a sensor from Stealers ... £70 + the dreaded   but he did say he'd give me "some" discount when I pick it up and pay ! None in stock so won't be in until Monday... gives me a couple more days to squirt plusgas at it I suppose

[terry paget]

When I removed my front sensor, the retaining screw came out OK, but the sensor was well and truly stuck in the hole in the hub. Wiggling the retaining screw end only succeeded in breaking it off. I then picked and drilled the sensor to death, slow business. What I should have done is remove the disc and bash it out with a socket.

It's worth checking that cable first!

[Entwood]

Stuck "my" version of how I changed the ECU up in the test section... hope I've not missed anything out !!

Well done, Entwood. I didn't say it was easy, but I found it much easier than unscrewing all the brake pipes from the ABS unit before removing it, screwing them all back afterwards, then bleeding all the brake circuits. I was not aware of the complications introduced by the LPG kit, glad you overcame them.

[Entwood]

Picked up the new sensor today .. listed at £69.00 + VAT = £82.80 .. didn't need to flash the Autobahnstormers card and ask for a discount .. came up automatically with the reg number ... Mr N R******** Autobahnstormers .. £51.02 + VAT =£61.23  .. now that's a decent discount. 

Looking at the forecast it won't get changed until Wednesday or Thursday .. not something I'm going to do in the pouring rain !!
