i have just bought a renault with tyre fault lights showing for no reason. i made an old (blown) fuse into a connector by soldering on 2 wires (one to each pin) then fitted an in line fuse/fuse holder and a small push switch,just under the ashtray by the diagnostic plug between those 2 wires, in series....now all i have to do is pull out the ashtray,start the car,press the switch to break the circuit,car stops running, remove keycard, press switch again to connect circuit,replace ashtray and re-start the car....display re-sets....i was going to put the switch somewhere more accessible,but...hitting it by accident and turning off all power at 70 in the fast lane would not be a good idea. i have to do this about 2 times a week,but it is cheap and effective(fuseholder +switch £4 at carspares) it is fuse 2 on my laguna, marked as "alim uch". i do check the tyres each time in case the crap system DID find a real fault!!!
