Hi I hope someone might have seen this before.
C4 Grand Picasso 2007
I put cruise control on and after 2 seconds the cruise control goes to off and the speed location flashes with the two lines.
No errors recorded in the log
Help!
C4 cruise control fault

Re: C4 cruise control fault
Could well be a faulty brake switch, I believe there was a modified switch/harness for early model C4 picassos. It may not show up as a fault as it may just think the brake is being pressed when its not being pressed so cutting off the CC.
Re: C4 cruise control fault
I had put the modified loom and brake switch in as we had the gearbox jumping from auto to manual. Which this fixed and the cc worked
I wonder if the new switch could have failed in 2 years though
