ok ill check that but why the brake lights affect the hdc light
'cause the brake-light switch is connected to both the brake-lights ..
and to hdc/tc part of the controlling computer ..
i.e. the switch has three wires ..
1 .. is a 12v supply feed
2 .. goes via the brake-lights to earth
3 .. goes to the computer box
( diagram in manual is downstairs .. can't remember if box is the egine 'ecu'
( or another black-box computing thingy .. as be another in the cab area
also where is the hdc switch located or do you mean on the gear selector
i mean the hdc switch which is either on the gear-selector itself
or down by the gear selector gaiter on the .. er .. mounting ring thing ?
be an offhand suggestion ..
as i'm not sure what could be disturbed when a clutch change is done ..
i.e. what wiring or plug/socket connections ..
