SEVERAL LIGHTS STARTED FLASHING ON THE DASHBOARD INCLUDING THE STOP SIGN AND THE SPEEDO WOULD NOT WORK.
WE TOOK IT TO OUR SMALL INDEPENDENT LOCAL GARAGE WHO COULD NOT LINK IT UP WITH THEIR LAPTOP PROGRAM.
WE THEN TOOK IT TO OUR MAIN PEUGEOT DEALER WHO SAID THAT FOR 65 POUNDS THEY WOULD LOOK AT IT WHICH WE PAID.
THEY TOLD US THAT IT WAS A PROBLEM NEEDING AN ABS CCU AND HAVE QUOTED 638 POUNDS INCLUDING LABOUR TO FIT.
possibly... its possible that on this model the speedo is run from the ABS sensors on the road wheels. i would have the sensors checked individually first by a reputable garage or vehicle electrician to make sure they are good and the respective wiring. only then could you point directly at the ABS control unit.
