I think I have the PDF at home somewhere.
Anyway. If the light goes out after starting the car the sensors are OK which is a good start. It means the chances are that its the target rings have been damaged or rotted away a bit and the pickups cant read them properly. If I go over 80mph in mine, it slings the ABS light on for the same reason. They're part of a first-gen electronic system and the tooth pattern is quite fine, 92 teeth, and this leaves them susceptible to degradation and damage from flying debris. More modern stuff from the next gen tends to be a 44-tooth pattern which are somewhat toughter (and cheaper, Megane rings are on the web for under £2!!)
Rears are well protected on Quadra by the hub assembly so try the fronts first. They are available new from Renault for about £40 last time I asked but I found these while eBay surfing the other week...

They're a press fit on the shaft, but I have very often changed them with a hammer and chisel, a drill-wire-brush and a bit of grease. Clean the face of the sensor with brake cleaner while the shaft is out and pick all the bits of crap stuck to it cos it's magnetic.
