Vauxhall Vectra abs/traction control lights & speedo fault

Car: Vauxhall Vectra
Variant: 2.0 litre GLS estate auto
Model Year: 1999
Categories: Leaks & Noises
driving along and speedo stopped working,ABS & Traction control lights came on.RAC & locaol independent Vauxhall garage cannot find fault on diagnostics computer. It is intermittent fault but a pain in the backside.Could it be ABS sensor,wheel speed sensor or body control module causing this?
Slight noise from rear wheel(possible wheel bearing needs replacing?)could this be the cause?

sounds like vehicle speed sensor vss fault if car doesnt know its speed screws up all sorts of sensor inputs,check location of sensor some vss are on abs rings some on gearbox sensor check plugs for coroision etc.may not show up on diag computor as car prob thinks its stopped.has abs/tcs memory been read for faults? if light on fault should be logged

Had it checked by four different diagnostic computers...none registered a fault anywhere.Would Speed sensor affect ABS etc?Been quoted £400+ to supply and fit new ABS sensor,dont want to do that if its something else.

Daft question....but where do I find this?

the wiring for the sensors on the front wheels is attached to the suspension legs but can detach and rub against the tyres so look behind the front wheels and follow the wiring to the back of the wheels
