Next step then is checking the wiring to the clutch switch might be chafed against the dash structure/steering column.
Had an issue with a Peugeot 405 where adjusting the steering column pinched the immobiliser/alarm wiring, so would not rule that out
Will check, though the wiring is very short. I checked the new Vx switch with a meter, worked OK. I swopped the switches, and checked the old switch, also OK. I then noticed that by sticking probes against the 2 pins to check continuity, I had bent one of them. I bent it bck as best I could.
I wonder if the original switch had gone in with bent pins, so when the plug was pushed in it did not go on to the pins, but bent one over. And did I inadvertently bend a pin when testing the new switch?
Am I right in saying that the live data should go from active to inactive on pedal depression, like the brake pedal?
