Can anyone please help? The ABS warning light is showing on my 1999 Mk2 1.8iS. There is a current being generated by the wheel sensors both front & rear when I jack up the car & spin the wheels. So I don't think it's a sensor issue.
I haven't got access to any diagnostic tools & I'm also not sure which diagnostic series is used, (OBD1, 2 & so on). I admit to being a bit thick where electronics are concerned!

Your car is not OBD compliant, so you’re wasting your time there.
However you can use the onboard diagnostics to identify the fault - highly likely to be a sensor. Don’t have the details to hand but involves putting ECU into a fault code mode using the underbonnet diag connector, then read off the blink codes on the dash.
The code will indentify individual sensor (or other problem).
On the presumption it’s a sensor (I reckon it will be), from experience - if you want to make life easiest for yourself, then buy a complete hub with sensor from a breaker. There are LOTS of suitable cars in breakers!
If you try remove a sensor from a hub, it will almost certainly snap and then you'll be stuffed, and end up removing the hub anyway. Hence my suggestion of getting a hub and known working sensor (makes it an easy bolt off, bolt-on replacement. The sensor cable can then be fed up through the wheel arch to the connector in the car.
Went through the exact same rigmarole on my 1999 car.
Get thee to google and dig out the fault code list, it’s definitely out there.

Thank you Snotrag. I have had a quick look at Google & a previous Pistonhead link popped up, the contributor there measured the resistance in the front sensors, one was off the scale & he thought replacing that one would cure his problem. The ABS unit has it's own ECU in the passenger footwell apparently, this cannot be read via the diagnostic plug under the bonnet. I will let you know how I get on (or not)!
